Forage fiber is a crucial component of livestock diets, providing essential nutrients and facilitating proper digestion. However, the level of undegraded forage fiber in these diets has been a topic of debate among animal nutritionists and researchers. Undegraded forage fiber refers to the portion of fiber that remains intact in the digestive tract without being broken down by rumen microbes. In recent years, there has been growing interest in the potential benefits of lower undegraded forage fiber levels in livestock diets. This article explores the rationale behind this trend and evaluates its implications for animal health and performance.

The Role of Forage Fiber: Before delving into the debate over undegraded forage fiber levels, it is essential to understand the role of forage fiber in livestock nutrition. Forage fiber encompasses both structural carbohydrates, such as cellulose and hemicellulose, and nonstructural carbohydrates, including pectins and lignin. These fibers provide bulk to the diet, promoting rumen motility and stimulating saliva production. Furthermore, microbial fermentation of forage fiber produces volatile fatty acids (VFAs), which serve as a significant energy source for ruminants.

Undegraded Forage Fiber: While microbial fermentation is essential for breaking down complex carbohydrates in the rumen, not all fiber undergoes this process. Some portions of forage fiber remain undegraded and pass through the rumen to the lower digestive tract, where they contribute to fecal bulk and promote hindgut fermentation. However, high levels of undegraded fiber may reduce nutrient digestibility and hinder overall feed efficiency in livestock.

Benefits of Lower Undegraded Forage Fiber: Advocates for lower undegraded forage fiber levels argue that reducing the amount of indigestible fiber in livestock diets can enhance nutrient utilization and improve animal performance. By optimizing the balance between degradable and undegradable fiber, producers can maximize feed efficiency without compromising digestive health. Furthermore, lower undegraded fiber levels may lead to reduced fecal output and improved manure management on farms.

Considerations for Implementation: While reducing undegraded forage fiber levels holds promise for optimizing livestock diets, several factors must be considered when implementing this approach. Firstly, producers must carefully select forage sources with favorable fiber characteristics, such as high digestibility and low lignin content. Additionally, dietary formulations should be tailored to meet the specific nutritional requirements of different livestock species and production stages. Regular monitoring of animal performance and digestive health indicators is essential to ensure that adjustments can be made as needed.

In conclusion, the debate over undegraded forage fiber levels in livestock diets highlights the complex interplay between dietary components, digestive physiology, and animal performance. While lower undegraded fiber levels may offer potential benefits in terms of nutrient utilization and feed efficiency, careful consideration must be given to factors such as forage selection, dietary formulation, and monitoring protocols. Ultimately, a balanced approach that takes into account the unique needs of individual livestock operations is essential for optimizing animal health and productivity.

In recent years, there has been growing interest in re-evaluating traditional practices in animal husbandry, particularly concerning the separation of calves from their mothers shortly after birth. A mounting body of evidence suggests that extending the duration of maternal care can have profound benefits for both the welfare of calves and the productivity of dairy and beef operations.

Traditionally, dairy and beef farming practices have involved early separation of calves from their mothers, often within hours or days of birth. This separation is primarily driven by the need to maximize milk production for human consumption and to facilitate management practices such as individual calf feeding and disease prevention.

However, research has increasingly shown that early separation can have negative consequences for both cows and calves. Calves experience stress and distress upon separation from their mothers, disrupting the natural bonding process and hindering their emotional and social development. Moreover, maternal care plays a crucial role in providing calves with essential nutrients, antibodies, and immune factors present in colostrum and milk, which are vital for their health and growth.

In response to these findings, some farmers and researchers have begun exploring alternative management practices that allow calves to remain with their mothers for a more extended period. This approach, often referred to as dam-rearing or cow-calf contact, involves keeping calves with their mothers for several weeks or even months after birth.

The benefits of extended maternal care for calves are manifold. Firstly, it promotes better physical health and growth. Calves that have access to their mother’s milk for a more extended period tend to experience fewer health issues, such as diarrhea and respiratory infections, and exhibit improved growth rates compared to artificially-reared counterparts.

Furthermore, extended maternal care supports the development of natural behaviors and social skills in calves. By allowing them to interact with their mothers and other herd members, calves learn essential social cues, establish hierarchies, and develop coping mechanisms that are crucial for their long-term well-being.

From an economic standpoint, there are also potential benefits to keeping calves with their mothers for longer. While there may be initial challenges in terms of management practices and milk production, the long-term gains in calf health and productivity, as well as potential improvements in cow fertility and longevity, can contribute to overall farm profitability.

In addition to the welfare and economic advantages, extending maternal care aligns with evolving consumer preferences for more ethical and sustainable farming practices. Consumers are increasingly concerned about the well-being of farm animals and are willing to support systems that prioritize animal welfare, including allowing calves to remain with their mothers for extended periods.

However, transitioning to extended maternal care practices requires careful planning and consideration of various factors, including herd management, infrastructure, and labor requirements. Farmers may need to invest in facilities that support cow-calf contact, such as spacious pens with shelter and adequate feeding areas, as well as develop protocols for monitoring cow and calf health and behavior.

In conclusion, there is growing recognition of the benefits of keeping calves with their mothers for longer periods in dairy and beef production systems. By prioritizing the welfare of calves and promoting natural behaviors, extended maternal care not only enhances calf health and productivity but also aligns with consumer preferences for more ethical and sustainable farming practices. As the agricultural industry continues to evolve, re-evaluating traditional practices and embracing innovative approaches to animal husbandry will be essential for building a more resilient and humane food system.

Dairy owners in the United States confront various obstacles in the calm milk market, including the possibility of declining profitability. As milk prices remain variable, dairy farmers may achieve profitability by focusing more on management, animal genetics, nutrition programs, and general efficiency.

Dairy farmers should explore selling carbon credits in 2024 and beyond, since they have been shown in study to reduce enteric methane while increasing milk output and feed efficiency. This initiative is already in place, with participating dairy farmers receiving compensation for reducing enteric methane while improving the sustainability of their operations. On-farm replacement heifer stocks should be reviewed on a regular basis, since having too many heifers takes up valuable facility space and depletes feed stockpile. An increasingly common strategy is to breed future dairy replacement heifers from heifers and first-lactation animals, whose genetic composition is statistically superior to that of older cows.

Maximizing farm-raised feedstuffs is critical for dairy farmers, since high-producing herds thrive on diets with forage levels of 60% or higher. High-oleic soybeans may be utilized as an on-farm protein source since they have a better fatty acid profile than normal soybeans do. Research has shown that feeding high-oleic soybeans may increase milk fat by 0.2 units when compared to normal soybean feeding.

Maximizing milk solids to promote energy-corrected milk (ECM) may result in a good return on investment while maintaining milk volume. Supplementing methionine hydroxy analog (MHA) and/or bypassing palm fat may increase butterfat percentages on-farm by 0.3-0.5%. Moving ahead, increased profitability targets will be aligned with maximum butterfat synthesis.

Cow grouping may enhance health, increase productivity, and generate cash above feed expenses. The advantages of correct grouping include a decreased frequency of metabolic diseases, cheaper feed costs, better reproduction, higher lifetime milk output, and optimal parlor flow. Grouping tactics based on parity and stage of lactation may assist dairy farmers in navigating these hurdles and achieving future profitability.

There are various ways that may be used to improve dairy operations. These include lowering feed shrink, improving feed bunk management, developing close-up dry cow diets, enhancing herd reproduction, and incorporating organic trace minerals.

Reducing feed shrink entails limiting losses at critical control points such as feed ingredient processing, storage, mixing and feeding, feed bunk management, and weather-related disruptions. Proper silage face management and frequent dry matter determination analysis on wet forages may also assist to prevent shrinkage.

Increasing feed bunk management entails creating a timetable that corresponds to the milking schedule, supplying new feed when cows return to the parlor, and arranging more push-ups throughout the day. Maintaining a uniform distribution of feed over the feedline guarantees that all cows may eat at their preferred place. Time-lapse cameras may be used to track regular chores and keep cows from running out of fodder.

During the transition phase, close-up dry cow meals reduce metabolic issues while increasing cow comfort by giving enough room for laying down and eating while limiting pen movements. Manage the feed bunk by adjusting intakes and utilizing only high-quality forages with sufficient fiber. Implement daily cow-level monitoring to check for changes in body temperature, activity, and eating behavior.

Continue to increase herd reproduction by employing systematic breeding programs and/or wearable technology to boost heat detection efficiency, first service, 21-day pregnancy rate, labor demand, and overall reproductive success. Using organic trace minerals may help optimize herd genetic potential, resulting in greater efficiency advantages such as higher milk supply, better reproductive performance, better hoof health, and a lower somatic cell count.

Successful dairy businesses are based on a trusted team of advisers that collaborate with farmers to offer something of value to the table. A successful team establishes objectives on a regular basis, communicates a vision, maintains priorities, and keeps each other responsible for achieving them. The farm manager/producer should facilitate and own the strategy, with the assistance of each team member’s area of expertise.

Developing a culture of continuous improvement on the farm is critical to success. Setting and setting down objectives for profitable improvements in the next year might help you track your progress over time. Contact your local Hubbard Feeds dairy salesperson for more information on these suggested adjustments.

In an era where wearable technology has become increasingly ubiquitous, it’s not just humans who are benefiting from fitness trackers – even cows are getting in on the action. With advancements in sensor technology and data analytics, farmers are turning to wearable devices to monitor the health, behavior, and productivity of their bovine companions.

Traditionally, livestock management has relied on visual observation and manual record-keeping to assess the well-being of cattle. However, these methods can be time-consuming, labor-intensive, and often provide limited insights into individual animal health and performance.

Enter fitness trackers for cows – innovative devices designed to collect real-time data on various aspects of bovine physiology and behavior. These wearable gadgets, typically attached to a cow’s ear tag or collar, are equipped with sensors that monitor parameters such as activity levels, rumination patterns, and even body temperature.

One of the primary benefits of cow fitness trackers is the ability to detect early signs of health problems or distress. Changes in activity levels or rumination patterns can indicate issues such as illness, stress, or discomfort, allowing farmers to intervene promptly and provide appropriate care. This proactive approach not only improves animal welfare but also helps prevent disease outbreaks and reduce veterinary costs.

Moreover, fitness trackers can provide valuable insights into the behavior and productivity of individual cows. By analyzing data on activity patterns and feeding behavior, farmers can identify high-performing animals, optimize feeding strategies, and even detect estrus or reproductive cycles more accurately. This data-driven approach to livestock management enables farmers to make informed decisions that enhance herd health and maximize productivity.

In addition to health and productivity monitoring, cow fitness trackers offer benefits in terms of herd management and resource allocation. By tracking the location of individual cows within a herd, farmers can identify social dynamics, monitor grazing patterns, and optimize pasture utilization. This information can inform decisions related to herd grouping, breeding strategies, and resource allocation, ultimately improving overall farm efficiency.

Furthermore, the data collected by fitness trackers can be integrated with farm management software systems, enabling farmers to access real-time analytics and insights from anywhere, using their smartphones or computers. This digitization of livestock management not only streamlines data collection and analysis but also facilitates data-driven decision-making and long-term performance monitoring.

While the adoption of cow fitness trackers represents a significant advancement in livestock management, there are challenges to consider, including cost, data privacy concerns, and technological barriers. However, as the technology continues to evolve and become more affordable, the benefits of real-time monitoring and data-driven decision-making are likely to outweigh these challenges.

In conclusion, cow fitness trackers offer a glimpse into the future of livestock management, where data-driven insights and wearable technology converge to optimize animal welfare, productivity, and farm efficiency. By embracing innovation and leveraging the power of data analytics, farmers can moo-ve towards a more sustainable and resilient agricultural future.

In a recent study published in the Journal of Animal Behavior, researchers have uncovered fascinating insights into the social dynamics of young cattle, particularly focusing on the performance of calves when housed in pairs.

Traditionally, livestock management practices often involve keeping animals in large groups or individually, with minimal consideration given to the potential benefits of pairing. However, this study suggests that pairing young calves may have significant advantages for their well-being and development.

The research team conducted experiments in which they observed the behavior and performance of calves housed both individually and in pairs. They monitored various parameters such as feeding behavior, growth rates, and social interactions to assess the impact of pairing on calf welfare and productivity.

Surprisingly, the findings revealed that calves housed in pairs exhibited several positive outcomes compared to those kept individually. One notable observation was the enhanced social interaction between paired calves. They engaged in more play behavior, such as running and butting heads, which are essential for developing social skills and establishing hierarchies within the group.

Moreover, paired calves demonstrated improved feeding efficiency. By sharing a living space, they seemed to stimulate each other to eat more frequently and consume larger quantities of feed. This resulted in better growth rates and overall development compared to their solitary counterparts.

The study also highlighted the psychological benefits of pairing for young calves. Being social animals, cattle thrive on companionship, and pairing provides them with the opportunity for social interaction and mutual support, reducing stress levels and promoting a sense of security.

These findings have significant implications for the management of young cattle in agricultural settings. Incorporating pair housing into livestock management practices could potentially improve calf welfare, enhance productivity, and contribute to more sustainable and ethical farming practices.

However, it’s essential to note that the success of pair housing largely depends on various factors such as space availability, social dynamics within the group, and management strategies. Further research is needed to explore optimal housing arrangements and address potential challenges associated with implementing pair housing on a larger scale.

In conclusion, the study sheds light on the importance of considering social dynamics in livestock management and highlights the potential benefits of pairing young calves. By promoting social interaction and improving welfare, pair housing offers a promising approach to enhancing the well-being and productivity of cattle in agricultural systems.

The January Dairy Margin Coverage (DMC) revenue above feed costs was computed at $8.48/cwt, resulting in indemnity payments of $761.56 per million pounds enrolled in the 2024 program. In 2023, eligible producers received indemnity payments for 11 out of 12 months, with an average monthly payout of $2.80 per cwt. The DMC program was approved in the 2018 farm bill to provide farmers with protection when the gap between the all-milk price and the average feed price falls below the producer-selected margin threshold. The FSA Administrator, Zach Ducheneaux, emphasized that DMC is a critical risk management instrument for dairy enterprises to financially withstand the multiple uncertainties that negatively effect milk market pricing. Gregg Doud, president and CEO of the National Milk Producers Federation (NMPF), invites every dairy farmer to seriously consider signing up for DMC, noting the program’s permanent inclusion of updated production records as well as current low producer margins.

Winson Agriculture, a UK-based agtech startup, has created an AI-powered bovine hoof monitor that can detect small temperature changes in cows’ feet or legs. The technology, financed by the British government, is being developed in collaboration with the Agri-EPI Centre and software company Rhyze Softworks. Elevated temperature is an early indicator of infection, appearing before the disease’s obvious symptoms. Early identification would enable dairy farmers to begin treatment right away, avoiding the economic and welfare consequences of lameness.

The Agri-EPI Centre is contributing R&D expertise and a 200-head herd at the Dairy Development Centre in South West England to test and enhance the tool, which is still in the prototype stage. The Hoof Monitor is affixed to the cows’ feet and can detect temperature changes in individual legs and feet, which distinguishes it from other monitoring technologies such as mobility scoring, accelerometer-based precision technology, and camera and AI-based visual gait analysis. Artificial intelligence is utilized to automate processes, eliminating the need for manual locomotion scoring.

Testing at the Dairy Development Centre is scheduled to continue until May 2024, when the system will be relocated to a bigger commercial dairy unit to examine its real-world capabilities. If everything goes well, early users may be able to test the technology by 2025.

Lameness costs the British dairy sector around £53.5 million per year, ranking second only to mastitis in terms of economic damage. The monitoring technology might help to reduce production inefficiencies and carbon emissions per liter of milk produced, hence boosting sustainability.

According to CattleFax, the beef-on-dairy program is predicted to reach 4 million to 5 million head in the United States, accounting for around 15% of total cattle harvest by 2026. This program is becoming more important for farmers, vets, and the industry, as the sexed-and-beef type of production becomes the norm. Veterinarians play an important role in assisting dairy farmers with the transition to this program, which will be critical to their long-term success.

The sexed-and-beef approach focuses on lowering heifer inventories by utilizing sex semen on a producer’s top heifers and cows, while maximizing returns in the remaining cows by combining beef genetics to generate a high-quality beef-cross. Most dairy producers have farms that fall into one of two categories: maintaining their present herd size with a commensurate cull rate, or increasing their cow herds internally to optimum growth via planned mating.

Veterans may help farmers make choices about beef-on-dairy production by understanding how many heifers each dairy farm needs and emphasizing health and reproductive practices to prevent heifer and cow mortality. Partnering with a genetics business or other specialist may assist in determining and achieving the optimal number of heifers for each farm.

Reducing heifer non-completion is critical since the majority of losses are caused by health or reproductive issues, as well as mortality. Stillbirth risk, cull risk, reproductive failure risk, and culling risk in pregnant heifers are all factors that contribute to this proportion being low.

In conclusion, the beef-on-dairy initiative is becoming more important to dairy farmers, veterinarians, and the industry. By understanding the two situations and using the sexed-and-beef paradigm, veterinarians may assist dairy farmers in making educated choices about beef-on-dairy production.

The article examines the significance of genetics in dairy production, with an emphasis on employing top genetics for replacement breeding and optimizing genetic development and herd health. It highlights the need of identifying top animals in the herd to optimize genetic advancement in heifer production and drive profitability, removing unfavorable characteristics from the herd, and producing high-value beef calves. The average cost of raising a heifer today ranges between $2,000 and $4,000, making it more crucial than ever for farmers to focus on profitable matings.

Heifers are regarded the most elite genetic animals on dairy farms, and utilizing sexed semen in them results in a greater return on investment. Genomics testing may assist farmers in selecting the finest animals, whether heifers, first-lactation or second-lactation cows, to get sexed semen. However, this procedure may be difficult to manage, and a breeding plan can guide farm staff on what to do when withdrawing an animal for insemination.

Step #3: Select the best semen product to help farms meet their short- and long-term business objectives. To lower expenses and increase beef-x-dairy profits, use sex-sorted semen that maximizes genetic improvement, health, fertility, and heifer ratios. Producers should choose the top 40% or so of the herd’s heifers for sexing, with the other 60% receiving beef semen. Semen purity is an essential factor in choosing the number of heifer matings to conduct, and genomic testing may assist identify people who have inherited genes that cause abortions or poor health.

Step 4: Recognize and exploit the characteristics that provide value to the chosen beef sire. Increase the value of beef-x-dairy profit by selecting sires that prioritize fertility, pricing, growth, efficiency, and yield. Everyone in the production chain has their own opinion on what makes a good beef sire, and dairy farmers want their cows to conceive, therefore fertility is the most important attribute.

According to Hockett, outdated inventory is no longer an issue in beef-x-dairy, since research demonstrates that conception rates in Holstein dairy cows are identical whether Angus or Holstein sires are employed. To meet demand, genetics firms must maintain low stockpiles. Sidestep discounts for different breeds, such as Charolais, Limousin, and Wagyu, may assist producers in establishing the value of beef-on-dairy calves and maintaining it over time in the business.

Optimizing dairy cow nutrition is crucial for ensuring herd health, milk production, and farm profitability. One often-overlooked aspect of feeding management is providing cows with access to well-mixed feed. This article delves into the importance of well-mixed feed for dairy cows and its impact on overall herd performance.

The Significance of Well-Mixed Feed: Well-mixed feed refers to a balanced blend of ingredients, including grains, forages, minerals, and supplements, thoroughly combined to provide consistent nutrition to dairy cows. Ensuring feed is properly mixed is essential for promoting rumen health, maximizing nutrient utilization, and minimizing feed wastage. When cows have access to uniform feed, they are more likely to consume a balanced diet, leading to improved milk production, reproductive performance, and overall well-being.

Benefits of Well-Mixed Feed Access:

1. Improved Nutrient Intake: Cows are selective feeders and tend to prefer certain ingredients over others. With well-mixed feed, cows have access to a uniform ration, ensuring they consume essential nutrients in the correct proportions for optimal health and performance.
2. Enhanced Rumen Function: The rumen, a fermentation chamber in the cow’s stomach, relies on a consistent diet to maintain microbial balance and fermentation efficiency. Well-mixed feed promotes rumen stability, reducing the risk of acidosis and other digestive disorders.
3. Increased Milk Production: Consistent access to a balanced diet translates to higher milk yields. Well-mixed feed provides cows with the energy, protein, and vitamins necessary for peak lactation performance, ultimately boosting farm profitability.
4. Reduced Feed Waste: Inconsistently mixed feed can lead to segregation of ingredients, resulting in cows picking and choosing certain components while ignoring others. This selective feeding behavior increases feed wastage and compromises nutritional intake. Well-mixed feed minimizes sorting behavior, reducing feed losses and improving feed efficiency.

Strategies for Ensuring Well-Mixed Feed:

1. Utilize Proper Mixing Equipment: Invest in high-quality feed mixing equipment capable of thoroughly blending ingredients to achieve uniformity.
2. Monitor Mixing Procedures: Train staff to follow standardized mixing protocols, ensuring consistent feed quality and nutrient distribution.
3. Conduct Regular Feed Analysis: Periodically test feed samples to verify nutrient content and assess mixing accuracy. Adjust formulations as needed to meet herd requirements.
4. Implement Feed Bunk Management: Manage feed delivery and access to encourage consistent intake among cows, minimizing competition and bullying at the feed bunk.

Providing dairy cows with access to well-mixed feed is a fundamental aspect of modern dairy farming. By prioritizing feed quality and consistency, farmers can optimize herd nutrition, health, and productivity. Investing in proper mixing equipment, adhering to mixing protocols, and monitoring feed quality are essential steps toward achieving well-mixed rations. Ultimately, ensuring cows receive a balanced diet translates to improved milk production, profitability, and sustainability for dairy operations.

The use of gene editing in cattle has resulted in bovine viral diarrhea (BVDV) resistance. This study, undertaken by USDA researchers and the University of Nebraska, intended to lower a calf’s vulnerability to BVDV. BVDV is a difficult cow illness that harms animal health by weakening the gastrointestinal tract, respiratory system, and reproductive function. It may also be a quiet plague, since sick animals can transfer it to their herd members while seeming healthy.

The researchers employed CRISPR/Cas9 gene editing technology to modify six amino acids in the CD46 gene, which is the site inside the cell where the virus cleaves and enters to infect and multiply in a new host animal. They utilized cloned Gir cow embryos and transferred modified cells to part of them, leaving the other half unedited and serving as “wild-type” controls. Eight embryos of each variety were transplanted into cows.

Of the resulting fetuses, one edited and one unedited fetus were collected at 100 days to assess BVDV resistance in cells from many bodily systems. Ultimately, one full-term pregnancy emerged from an altered embryo, and the calf was delivered by cesarean section at 285 days gestation.

The research discovered that the altered calf was considerably less susceptible to BVDV in a laboratory environment than the unedited fetus. Live tissue samples revealed that the altered calf had a much lower BVDV susceptibility in the three cell types studied – skin fibroblasts, lymphocytes, and monocytes – than the unedited control calf.

The research also found that although gene editing did not completely protect the calf from BVDV, it did greatly increase its capacity to tolerate the viral onslaught. The commercial use of such technology has yet to emerge, but the capacity to help cattle fight BVDV has potentially far-reaching consequences.

A Penn State study discovered that supplementing high-producing dairy cows with the botanical extract capsicum oleoresin, derived from chili peppers, or a combination of that extract and clove oil resulted in the animals using feed energy more efficiently and emitting less methane from their largest stomach. The cow would use the available energy on body weight increase rather than milk production or milk components.

The data imply that supplementing with this botanical combination may have a good physiological and environmental impact. The researchers understood that botanicals had the ability to alter fermentation in the dairy cow’s biggest stomach, known as the rumen. In a nearly two-decade-long attempt to boost milk output and minimize environmental emissions from dairy farms, they have experimented with supplementing the diet of high-performing dairy cows with anything from seaweed to garlic and oregano oils to synthetic chemicals.

Methane, a strong greenhouse gas produced by cows’ belching, is the product of fermentation in the cow’s rumen. This technique enables the animal to eat and use fibrous meals and waste that are indigestible to humans or other agricultural animals with simple stomachs. The combination of capsicum oleoresin and clove oil reduced methane output and intensity in the study’s cows by 11%, with the effect being most noticeable in first-lactation cows.

Botanicals, also known as phytonutrients, are plant-derived bioactive chemicals that have antimicrobial activities against bacteria, protozoa, and fungus. Studies on non-ruminant species have demonstrated that phytonutrients may cause particular gastrointestinal and immune responses in animals. Various botanicals containing active compounds such as eugenol, cinnamaldehyde, allicin, and capsaicin may stimulate immunological responses, decrease oxidative stress, and impact insulin secretion and function.

In a 10-week study at the Penn State Dairy Barns, 48 Holstein cows were randomly allocated to one of three food regimens. The research discovered that cows supplied with capsicum oleoresin or a mixture of capsicum oleoresin and clove oil used energy more efficiently.

Virginia Tech researchers are deciphering cow vocalizations using acoustic data and machine learning, with the goal of improving animal welfare and lowering methane emissions via precision livestock farming. James Chen, an animal data sciences researcher and assistant professor, is utilizing a $650,000 grant from the USDA’s National Institute of Food and Agriculture to create an acoustic, data-driven tool for analyzing cow vocalizations for indicators of stress or sickness.

Cows convey their feelings via vocalization, and we must pay attention to what they are saying. Sound data may be obtained from cows individually and constantly, making it superior than video or other techniques of observing cows’ emotions and health. By combining auditory data with biological and visual clues, we may be more objective in our analysis of behavior.

Chen and his co-investigator, Virginia Cooperative Extension dairy scientist and associate professor Gonzalo Ferreira, want to gather audio data from cows, calves, and beef cattle on the grassland. They will next use machine learning to evaluate and categorize hundreds of audio data points, as well as interpret cow vocalizations like mooing, munching, and burping for indicators of stress or disease.

Chen and Ferreira are especially interested in discovering the vocal patterns used by cows to indicate discomfort. By monitoring the frequency, amplitude, and length of cow moos and vocalizations and matching the sound data with saliva cortisol samples, scientists may determine if cows are under no stress, moderate stress, or severe stress, and begin to interpret their “language.”

The collected data will be made accessible via an open-source, web-based tool for scientists, producers, and the general public. The ultimate objective is to use this methodology on a broader scale, creating a public dataset to guide legislation and laws.

Mastitis, a pervasive ailment among dairy cattle, poses a significant threat to both animal welfare and farm profitability. However, advancements in precision treatment strategies have emerged as a beacon of hope for dairy farmers striving to mitigate losses associated with this affliction.

Mastitis, characterized by inflammation of the udder tissue, not only compromises milk quality but also leads to decreased milk production, increased veterinary costs, and potential culling of affected animals. Consequently, addressing mastitis promptly and effectively is paramount for dairy operations.

Traditionally, mastitis treatment involved broad-spectrum antibiotics administered to the entire herd or affected animals based on visual symptoms. However, such an approach often resulted in overuse of antibiotics, contributing to antimicrobial resistance and increasing treatment costs. Moreover, indiscriminate antibiotic use raised concerns regarding milk residue and food safety.

Enter precision treatment methods, which offer a more targeted and efficient approach to mastitis management. These methods leverage technological innovations such as on-farm diagnostic tools, data analytics, and herd management software to identify mastitis cases accurately and tailor treatment plans accordingly.

One notable example is the utilization of milk somatic cell count (SCC) as a diagnostic tool. Elevated SCC levels indicate the presence of mastitis, enabling early detection of subclinical cases before visible symptoms manifest. By regularly monitoring SCC levels, dairy farmers can identify affected animals promptly, allowing for timely intervention to prevent the spread of infection and minimize production losses.

Additionally, advancements in microbial testing have facilitated the identification of the causative pathogens behind mastitis cases. Armed with this knowledge, veterinarians can prescribe targeted antimicrobial therapies, thereby optimizing treatment efficacy while reducing the risk of antibiotic resistance development.

Furthermore, the integration of data analytics and artificial intelligence into herd management systems has revolutionized mastitis prevention and control. These technologies analyze vast amounts of data, including individual cow health records, environmental factors, and milking practices, to identify potential risk factors contributing to mastitis outbreaks. By proactively addressing these factors, such as optimizing cow comfort or adjusting milking procedures, farmers can reduce the likelihood of mastitis occurrence and minimize associated losses.

Beyond treatment and prevention, precision methods also encompass strategic decision-making regarding the culling of chronically infected animals. By accurately assessing the cost-benefit ratio of retaining or removing affected cows from the herd, farmers can optimize long-term profitability while maintaining herd health and productivity.

In conclusion, precision treatment methods represent a paradigm shift in mastitis management, offering dairy farmers a more accurate, cost-effective, and sustainable approach to curbing losses associated with this prevalent ailment. By embracing these innovations and integrating them into their management practices, dairy operations can safeguard animal welfare, enhance milk quality, and bolster profitability in the face of mastitis challenges.

6. Feedback Integration into Decision-Making: Integrate feedback into the decision-making process to ensure that team members’ voices are heard and valued. Whether soliciting input on farm strategies, process improvements, or resource allocation, involving the team in decision-making fosters a sense of ownership and commitment to shared goals.
7. Continuous Improvement Loop: Establish a continuous improvement loop where feedback is actively sought, implemented, and reassessed. By regularly evaluating the effectiveness of feedback mechanisms and adjusting strategies as needed, the team can adapt and evolve in response to changing dynamics and challenges.

In conclusion, harnessing feedback as a tool for growth and development is essential for building a strong and cohesive team on the dairy farm. By prioritizing open communication, recognition, and continuous improvement, dairy farm operations can empower team members to excel individually and collectively, ultimately driving success in an ever-evolving industry.

According to the USDA’s most current Cattle report, the number of dairy heifers available to replace older cows leaving the US dairy herd has decreased by over 15% over the previous six years, hitting a 20-year low. This reduction may impede any major increase in domestic milk output during the next several years. The growing cost of raising dairy heifer calves has far outpaced gains in heifer values in recent years, prompting dairy farmers to lower their heifer replacement inventories, mostly by breeding more dairy heifers and cows to beef bulls.

In recent years, most farms have lost money raising dairy heifers, with expenditures ranging from $600 to $900 per animal. To better manage on-farm heifer inventories, dairy producers have begun to use beef semen on a section of their dairy herd, reducing the number of replacement heifers while also generating extra cash from beef sales.

The disparity between raising expenses and selling value has resulted in a lengthy and steady fall in replacement heifers in recent years. While some variation in the population of replacement heifers is unavoidable due to market and economic pressures, an adequate inventory is vital to the continuation of U.S. milk supply and the industry’s capacity to grow.

The sharp decline in heifer supplies remained mostly ignored until lately, when dairy producers sought to purchase now-scarce replacements. As a consequence, dairy replacement costs have risen to an eight-year high, with USDA statistics and auction market estimates ranging from $1,890 to $2,800 per cow. Given the scarcity of replacements, these elevated prices are likely to remain in place for the foreseeable future.

Dairy calves are born with little to no immune protection, thus they need high-quality colostrum for passive immunity transmission. Passive immunity transfer occurs when a calf absorbs IgGs from colostrum; generally, 4 liters of high-quality colostrum (Brix% > 22) is given during the first four hours after birth. There are four types of passive transmission of immunity: outstanding, good, fair, and poor. A recent research in the Journal of Dairy Science compared calf health indicators and average daily gain (ADG) to these classifications.

The trial included roughly 3400 calves from a single farm that were given 4 liters of high-quality colostrum via an esophageal tube feeder within 30 minutes of delivery. The calves were then kept in solitary pens for the first few days of life before being transferred to group enclosures of ten animals at three weeks old. The findings revealed that 4.8% had poor passive transfer of immunity, 29.5% had fair, 28.3% had good, and 37.4% had exceptional.

The research also discovered that variables such as the dam’s lactation number, the individual employee giving the colostrum, and the ease of calving all had an impact on passive immunity transmission. Calves born to moms in their third or later lactation exhibited less passive transmission of immunity. Cows having dystocia and requiring help during birth had calves with reduced passive immunity transfer.

Good management techniques are critical for dairy cattle because unique personnel might influence passive transmission of immunity. Employee training and frequent procedural checks are crucial. Dystocia may be avoided by mating cows to bulls with a high calving ease score and ensuring heifers have the appropriate size and maturity when they calve. Animals should calve at a body condition score of 3.5 to ensure they have enough weight to drop before entering a negative energy balance and producing milk.

Colostrum is only considered high-quality if it is free of excessive germs. Colostrum should be collected in a sanitary container and supplied from a properly sterilized bottle. If not given quickly, the bacteria concentration of the colostrum will increase every 20 minutes, endangering the calf’s health. To establish a productive cow, a professionally educated person should give high-quality colostrum within a few hours after delivery.

No one can predict the future. But, thanks to data management tools, we can reflect on where we’ve been and use industry-leading insights to guide where we want to go. Reviewing your dairy’s data routinely will help you understand your farm’s complete picture.

While analyzing the data, ask questions and reflect on your goals. Are you reaching them? What changes have you made, and how does the data reflect those changes? Are any common challenges highlighted in the data?

“Numbers in a table are great, and looking at a graph can help visualize precisely what is happening on your dairy,” says Taliah Danzinger, senior manager of dairy intelligence at VAS. “Using those graphs to look at data collected over an extended period, 18 months to two years, can highlight seasonal or annual trends.”

Here’s a look at how to get the most from your data to inform your future.

From the past into the future

One way to make an informed decision about the future is to look to the past. Is there a challenge that happens every year on your farm? Do you have a similar issue that occurs every spring?

Data management tools, like HealthVAL and Reproduction Insights in DairyComp, allow you to pull graphs easily for various timeframes to zero in on your herd’s health and reproduction performance. Once you can see the data, catching those seasonal and yearly trends becomes easier.

Then, understanding what caused those trends can help you better predict what may occur in the future and prepare for it. What may have influenced the trend? Have you made any recent changes in management, facilities or protocols? Changes in feed?

“When discussing seasonality and yearly trends, most think of heat stress and its effects. While this is a common example, there are other influences,” says Danzinger. “In many cases, there is a logical explanation that can be solved with changes to management.”

For example, a farm experiences more ketosis events each year around September. During this time, they transition to new crop corn silage in the ration. The dairy can potentially mitigate this issue by being more intentional with silage inventory and carryover.

With the right tools, you can pinpoint trends in your dairy’s data, implement effective management changes and consequently enhance herd health and profitability. This proactive approach allows for better control and mitigation of recurring trends in the future.

Don’t underestimate calf and heifer data

The data you collect on your calves and heifers, like illnesses and management, can help you analyze and anticipate lifetime and production potential.

“We have so much to gain from tracking data on our calves and heifers, and it has never been easier,” says Danzinger. “With mobile cowside technology, or in this case, calfside, we can capture data on the fly and use it for long-term tracking.”

You can use data from birth through the heifer stage in a variety of ways, including:

• Setting goals for how many health events are acceptable for a calf and creating a plan to reach that goal.
• Managing inventory to determine who is best to keep in the herd based on performance data.
• Building a breeding program around the data that influences breeding, including market prices for calves and heifers, culling rate in the herd, and desired age at first calving.
• Assessing first lactation performance to evaluate how calfhood events influence lactation production and potential.
• Prepare for a successful year (and future)

Without interpretation and analysis, data is just numbers. It can only work for us if we work with it. The key? Intentionality. Setting aside time to review your data routinely and make connections is the start of implementing good data stewardship and management practices throughout the year.

“How your data in different management areas of the farm connects tells the story behind the numbers,” says Danzinger. “Without understanding that story, it is difficult to continue your dairy’s success or build and improve upon its challenges.”

The past explains where we have been and where we are today, but it can also inform us of what is to come. Keeping an inventory of your management changes can help you interpret their effect on your dairy’s performance based on trends in the data.

All these things play into the story behind your data, and if you’re intentional about reviewing it with your team and connecting the dots, you can set yourself up for a solid future.

“The best way to take advantage of your data is to lean on the people surrounding your dairy, your management team, trusted advisors and data experts, and the tools built to make data management easier,” says Danzinger.

Researchers at the University of Guelph are looking at the link between a cow’s personality and her milking ability. Dr. Trevor DeVries, a professor in the Department of Animal Biosciences at Ontario Agricultural College (OAC), has conducted a number of studies on the various character and temperament traits of dairy cows and how they affect their behavior and production in automated milking systems (AMS). The significance of this study rests in knowing how various personalities affect milk output in cows.

To assess personality in a cow, researchers transfer them to a new enclosure and study their behavior for 10 minutes. They next introduce an item that the cow has never seen before, such as a yoga ball, and observe their behavior for another 10 minutes. Finally, they bring a new individual inside the pen for an extra ten minutes. The time spent on each kind of behavior is divided by the overall length of the test, yielding a percentage of test time.

A Principal Component Analysis is used to identify cows with similar habits and group them together. A recent research by Dr. DeVries and PhD student Anna Schwanke found that cows with high boldness and activeness adapted better to the AMS soon after calving, but cows with low activeness and high boldness fared better in terms of milk supply and milking activity in early lactation.

Dr. DeVries and MSc student Sabina Czachor also investigated the relationships between dams’ personality qualities and their offspring, finding favorable links between active dams and exploratory-active heifers or active dams and brave heifers. This information might be utilized to choose a certain kind of cow or to adjust management to adapt or shape personalities.

Effective training is essential for workers to understand what has to be done and how to execute it, which is a fundamental need of every firm. Richard Stup, who has been working with farmers on staff development for over 20 years, believes that training is an essential component of managing a well-led team. Training is vital for new workers and team members who may be taking on new or increased responsibilities.

To create a positive training experience, farm owners should choose the best individual to teach them, taking into account their work expertise, passion in the task, and willingness to assist a newcomer. Farm owners should also break down linguistic barriers to deliver training that is actually effective.

Good training begins with the trainer’s preparation, which includes giving out the justification (why) for the task and defining what the employee wants to be able to perform after the training is over. Active, engaging options include practicing the activity in a controlled setting, discussing it with someone else, or selecting the best option from a list of possibilities.

When it comes time for training, Stup suggests using the “tell, show, do, review” cycle. Explain to the employee what they will learn and why it is essential, teach them what to do, and have them complete an assignment that demonstrates what they learned. Evaluate if they learned the assignment well enough and, if so, congratulate them. If not, praise the things that went well while providing criticism on the areas that were missed. Repeat the process until they have a firm handle on the whole work.

Investing in effective training can benefit both workers and the company in the long term, since doing the task correctly saves time and effort compared to an untrained person missing critical stages and needing to be redirected.

A research undertaken by AFBI in Northern Ireland looked at the advantages of autonomous milking systems and their influence on milking, yield, and concentrate consumption. The research believed that cows with high energy needs, such as those in early lactation or high producing, were not ingesting adequate concentrates for maintenance and productivity. To address this issue, some farmers are constructing out-of-parlour feeders that allow for more concentrate ingestion. However, it is critical to determine if feeding more concentrate via out-of-parlour feeders would have a negative influence on robot visit frequency.

The trial housed 48 cows with one milking robot and two out-of-parlour feeding. The PMR, which included 80% grass silage and 20% wholecrop, plus a 2kg concentrate mix per cow, was given once daily. The cows were divided into two groups: ‘robot high’ animals, which got 80% of their increased concentrate diet at the milking robot feeding station and 20% via out-of-parlour feeders. The second group, ‘robot low’ cows, got 20% of their supplemental concentrate from the milking robot feeding station and 80% from out-of-parlour feeders. These extra concentrate volumes were allocated on a feed-to-yield basis, although a minimum of 1kg per cow per day was always provided via the milking robot feeding station.

The research looked at how concentrate allocation affected trips to the milking robot and out-of-parlour feeders, as well as concentrate and PMR consumption, milk output, and laying time. The frequency of successful and failed milking trips did not change across groups. However, visit rates to out-of-parlour feeders varied, with ‘robot high’ cows visiting the feeders 8.01 times less per week than ‘robot low’ cows.

The study discovered that when cows were given the majority of their concentrate ration in out-of-parlour feeders, milking frequency was unaffected, yield was unaffected, and cows who received the majority of their concentrate within the milking robot did not have a higher number of unsuccessful milking visits. As a result, the laying time was unaffected.

Interestingly, cows having a greater allocation inside the out-of-parlour feeders visited them more often, indicating that cows may vary their visits as required to meet their energy needs. Milk output was consistent independent of feed allocation patterns, although cows with larger allocations inside the milking robot left more concentrate unconsumed, which is a source of worry.

In terms of PMR intake, cows fed more concentrate in the milking robot had lower PMR intakes in week 1 than those fed more concentrate in the out-of-parlor feeder, but the benefits did not last longer.

Farmers should ensure that cows do not get too much concentrate feed from the milking robot.

The United States Department of Agriculture (USDA) has announced loan interest rates for February 2024, effective the beginning of the month. The Farm Service Agency (FSA) strives to help agricultural farmers improve their operations, purchase required equipment, and manage cash flow issues. The USDA’s loan programs are designed to suit the different requirements of farmers, including veterans and those just starting out. The rates for February 2024 include farm operating loans at 5.125%, farm ownership loans at 5.375%, special rates for joint financing at 3.375%, down payment loans at 1.500%, and emergency loans to offset real losses at 3.750%. The USDA also works with commercial lenders to provide guaranteed loans, giving farmers another option for securing financing at reasonable rates. The FSA’s endeavor to shorten the loan application process using online resources and a streamlined paper application is part of a larger push to improve customer service and operational efficiency.

Precision feed management is dependent on the quality of a farm’s homegrown forages, since they determine the composition of the diet. A dairy may use a high-forage diet to improve cow health and income over feed cost (IOFC). Maximizing IOFC is critical for correctly feeding cows, since grain cannot entirely compensate for the nutritional gap caused by inadequate forage quality. To establish a solid fodder foundation, farmers should harvest at the appropriate stage and store them properly.

According to a Penn State Extension research, the capacity to manage fodder quality and inventory was the most important predictor of profitability among dairy farms evaluated. Crops should be harvested at the peak of their ripeness. Farms should aim for high-quality feed from every acre rather than entering a cropping season with the expectation of knowing which areas would produce poorly or provide low-quality feed.

Hunch maturity is one of the most important factors influencing corn silage quality, therefore it is critical to regularly monitor total plant dry matter and kernel maturity. To produce high-quality feed, consider cut length, cutting height, and kernel processing score during harvest. Maturity is also important for hay crops, especially at the initial cutting, since it influences fiber digestibility.

Start with heaps that are adequately sized for daily clearance and keep various feeds or quality levels in separate storage areas. Consider storage density and ensure that piles are adequately covered to exclude oxygen. A research-backed inoculant could be an excellent option.

Feedout is a vital stage because it entails reintroducing oxygen into fermented, stable feed. Samples should be obtained upon ensiling to determine what you’re beginning with, and then again while feeding. Forage quality is determined by providing the appropriate quality to the appropriate animals, which is accomplished by precision feeding.

Succession planning is a crucial aspect of any business, and dairy farming is no exception. For family-owned dairy farms, creating a well-thought-out succession plan is essential for ensuring the smooth transition of operations from one generation to the next. In this article, we will explore the importance of succession planning for dairy farmers and provide insights into creating effective strategies for a successful transfer of leadership and ownership.

The Significance of Succession Planning in Dairy Farming:

1. Preserving Legacy: Succession planning is vital for preserving the legacy of a dairy farm. Many family-owned farms have a rich history and deep-rooted connections to the community. A well-executed succession plan ensures that the values, traditions, and hard work invested by the previous generation are carried forward.
2. Sustainable Business Continuity: Dairy farming is not just a job; it’s a way of life. Effective succession planning ensures the seamless continuity of the business, preventing disruptions in daily operations. This is crucial for maintaining a sustainable and profitable dairy farm for years to come.
3. Financial Stability: Succession planning involves careful financial considerations. By addressing issues related to ownership, taxation, and estate planning, dairy farmers can mitigate potential financial challenges during the transition. This helps in maintaining the financial stability of the farm and ensuring its prosperity in the long run.

Key Steps in Creating a Succession Plan for Dairy Farmers:

1. Start Early and Communicate: Begin the succession planning process well in advance. Open and honest communication among family members is key. Discuss individual goals, aspirations, and expectations to ensure everyone is on the same page. Starting early allows for a smooth transition and minimizes conflicts.
2. Identify and Develop Successors: Identify potential successors within the family who are interested and qualified to take on leadership roles. Provide opportunities for them to gain hands-on experience and gradually take on more responsibilities. Training and mentoring are crucial for preparing the next generation of dairy farmers.
3. Legal and Financial Considerations: Consult with legal and financial experts to address ownership structure, tax implications, and estate planning. Establishing a clear legal framework ensures a smooth transfer of assets and minimizes the risk of disputes. Financial planning is essential to secure the economic stability of the farm.
4. Document the Plan: Formalize the succession plan in writing. This document should outline the roles and responsibilities of each family member, the timeline for the transition, and any other relevant details. Having a written plan helps in avoiding misunderstandings and provides a clear roadmap for the future.
5. Regularly Review and Adjust: The agricultural industry is dynamic, and circumstances may change over time. Regularly review the succession plan to ensure its relevance and make adjustments as needed. This flexibility is crucial for adapting to evolving market conditions, family dynamics, and individual aspirations.

Conclusion:

Succession planning is a critical aspect of securing the future of family-owned dairy farms. By starting early, communicating openly, and addressing legal and financial considerations, dairy farmers can ensure a smooth transition of leadership and preserve their farming legacy. A well-executed succession plan not only safeguards the continuity of the business but also contributes to the long-term success and sustainability of the dairy farm for generations to come.

Bovaer, a feed component, has been authorized in Canada to minimize methane emissions from beef and dairy cattle. Bovaer neutralizes methane in the rumen, which is produced when bacteria degrade feed, releasing hydrogen and CO2. Dsm-firmenich, a Dutch business, aims to make the product accessible in Canada within a few weeks. Bovaer has already been authorized in many regions throughout the globe, including Europe, Brazil, and Australia.

Using the substance, Canadian livestock feeders may lower methane emissions by up to 45 percent on average. For dairy cows, Bovaer may cut methane emissions by 30% on average, possibly decreasing the entire greenhouse gas footprint per liter of milk by 10 to 15%. Canadian study has shown a little improvement in feed efficiency but no change in cattle growth rate.

The approval follows the CFIA’s approval of the active component in Bovaer, 3-Nitrooxypropanol (3NOP). The Canadian Cattle Association’s president, Nathan Phinney, is delighted with the regulatory avenue available for new feed components that lower methane emissions, helping the industry reach its 2030 emissions target.

According to a CCA/National Cattle Feeders’ Association announcement, 3NOP has shown no deleterious effects on the rumen microbial community when given to cattle. The Canadian beef sector plans to cut primary production greenhouse gas (GHG) emissions intensity by 33% by 2030, whereas Dairy Farmers of Canada aspires for net zero emissions by 2050.

Enteric methane emissions from cattle account for 3.3% of Canada’s total GHG emissions. The product has been authorized in over 50 nations, but not yet in the United States.

Over the last five years, the amount of purebred dairy cows traveling through feedlots has declined dramatically. Dairies currently account for around 23% of total fed steers and heifers in the United States, with numerous factors contributing to this increase. One of the most significant impediments is the terrible drought that has covered most of the Midwest, forcing herd cutbacks in the cattle business. With the traditional cattle herd presently in liquidation, feeder calf prices have risen, causing a supply and demand imbalance between the beef sector and feedlots. Dairy farmers have helped fill the pipeline by producing beef-on-dairy calves and profited handsomely in the process.

Beef-on-dairy cross animals operate effectively in the beef supply chain system due to their uniformity. Dairy producers may supply premium meat to the pipeline while still making a sizable profit. To do so, however, farmers and feedlots must breed and feed these animals effectively. As the number of beef-on-dairy animals in the feedlot system increases, feedlots are looking for two crucial pieces of information to assist these crossbred cattle thrive:

1. Health Records: Buyers want to see that the animals they are acquiring have been well-cared for. Feedlots are specifically searching for beef-on-dairy animals that have had colostrum, been vaccinated, and have been subjected to the least amount of stress. Knowing when and what immunizations or medications were administered, as well as information on any health occurrences, is very useful data to provide. Feedlots can make better treatment options and comprehend a given animal’s performance indicators if they know its health state before it reaches the facility.

2. Nutrition Records: Moving a beef-on-dairy calf to the feedlot may be a traumatic experience. Halfa suggests that dairy farmers offer nutritional information to feedlots for beef-on-dairy calves sold after weaning. Providing feedlots with past diet information as well as the date the animal was weaned are two good pieces of information to provide.

Communication, traceability, and measurement are other important considerations. Communication and a well-established connection will always be required when selling cattle to purchasers. Dairy farmers excel at delivering timely and correct information, which not only provides purchasers with vital information but also opens doors to increased market access and the farm’s reputation for producing high-quality animals. Understanding the parameters for how these animals should be treated and fed in feedlots will assist increase the value of the animals delivered to market.

Beef-on-dairy is a procedure in which cattle are crossbred with dairy and beef cows to create a better grade beef calf. This approach blends dairy and beef cow qualities, with the goal of extracting characteristics from the beef breed and producing a higher-quality, higher-yielding product.

Sex-sorted semen has gained popularity in dairy herds, enabling farmers to genetically progress heifer calfs more quickly. This has resulted in a more diverse income for farmers while also teaching them about customer expectations and the requirements of the cattle market. The animals participating in this approach spend less time on feed, resulting in faster calves in and out, while packers profit from a more consistent product comparable to straight beef calfs.

Producers have found this approach to be economically advantageous since they pay the same amount but get more value out of the calf. This greater value results in more meat, marbling, and yield, making the calf more desirable. Crossbred calfs are more enticing because they have the size and marbling of a dairy ribeye.

These farmers get tremendous value, since they receive a $200 calf instead of $50 for plain dairy. This reduces costs for higher-quality products because they provide a better return on investment. Furthermore, the availability of these items has expanded, resulting in a more competitive pricing of beef products that are more accessible to the general public.

In conclusion, beef-on-dairy is a process in which cattle are crossbred with dairy and beef cows to generate a higher-quality, higher-yielding beef calf. This approach has grown in favor among ranchers and other industry participants, with producers benefiting from expanded economic opportunities and access to high-quality goods.

Harper Adams University researchers investigated the effects of dietary crude protein content and supplementing a low crude protein diet with dietary starch or rumen-protected Met (RPMet) on dairy cow performance, metabolism, and nitrogen use efficiency when fed red clover and grass-based silage. The research included 56 Holstein Friesian dairy cows that were randomly assigned to one of four diets throughout a 14-week feeding period. The diets were designed to provide comparable metabolisable protein content, with crude protein concentrations of 175 g/kg dry matter (CON), 150 g/kg dry matter (LP), or LP supplemented with extra barley as a source of starch (+64 g/kg dry matter; LPS) or RPMet (+0.3 g/100 g MP; LPM).

Following the 14-week feeding period, 20 cows (5 per treatment) were given the same diets for an additional 6 days, and total urine output and faecal samples were collected. The researchers discovered that dietary treatment had no effect on dry matter consumption, but there was a diet-week interaction, with intake greatest in cows given LPS in week 4 and CON in weeks 9 and 14.

The research discovered that lowering the crude protein content of red clover and grass silage-based diets from 175 to 150 g/kg DM while maintaining MP supply did not effect performance, but did decrease urinary nitrogen excretion and increase nitrogen usage efficiency. Supplementing with extra starch or RPMet had minimal impact.

Further details of the study can be found here.

In the dynamic and challenging world of the dairy industry, leadership extends far beyond managing operations and making decisions. A successful dairy leader is one who recognizes the pivotal role that relationships play in the overall success of the farm or dairy business. From fostering trust with team members to building connections with suppliers and stakeholders, effective dairy leadership is deeply intertwined with the quality of relationships established.

Building Trust with Team Members:

Dairy farming is a collaborative effort that involves the dedication and hard work of a team. The foundation of a thriving dairy operation lies in the trust established between the leader and the team. Leaders who prioritize open communication, provide support, and create a positive work environment cultivate a culture of trust. This trust is essential for smooth operations, increased productivity, and the overall well-being of the workforce.

Effective Communication in Dairy Operations:

Communication breakdowns can have significant consequences in the dairy industry, where precision and timing are critical. Dairy leaders must excel in both giving clear instructions and actively listening to the insights and concerns of their team members. A leader’s ability to communicate effectively ensures that everyone is on the same page, reducing the likelihood of errors and fostering a cohesive work environment.

Collaboration with Suppliers and Stakeholders:

The success of a dairy operation is not limited to what happens within the farm gates. Leaders in the dairy industry must also cultivate strong relationships with suppliers, veterinarians, and other stakeholders. Collaborative partnerships ensure a reliable supply chain, access to quality resources, and a supportive network that contributes to the sustainability and growth of the dairy business.

Adapting to Change and Market Dynamics:

Dairy farming is subject to various external factors, including market fluctuations, regulatory changes, and environmental considerations. Leaders who understand the importance of relationships can navigate these challenges more effectively. By staying connected with industry experts, peers, and relevant organizations, dairy leaders can adapt to changing circumstances, implement best practices, and position their operations for long-term success.

Empathy and Employee Well-being:

Dairy farming is often a demanding and physically intensive occupation. Leaders who prioritize relationships with their team members understand the importance of empathy and employee well-being. Providing support, recognizing accomplishments, and addressing challenges with compassion contribute to a positive work culture, enhancing job satisfaction and retention within the dairy workforce.

Inspiring a Sustainable Vision:

Leadership in the dairy industry extends beyond day-to-day operations; it involves envisioning a sustainable future. Leaders who forge strong relationships within the community and industry can inspire collective efforts toward sustainable practices. By fostering connections with environmental organizations, policymakers, and consumers, dairy leaders can contribute to the industry’s positive image and long-term viability.

In the intricate tapestry of dairy leadership, relationships form the backbone of success. From building trust within the team to collaborating with external partners, effective dairy leadership hinges on the quality of connections forged. As the dairy industry continues to evolve, leaders who prioritize and nurture relationships will find themselves better equipped to navigate challenges, inspire innovation, and ensure the long-term prosperity of their dairy operations.

Silage inoculants play a crucial role in the ensiling process, aiding in the preservation of forage quality and preventing undesirable fermentation. However, dairy farmers often find themselves with leftover silage inoculants after the ensiling season. This article explores the practical considerations associated with using leftover silage inoculants, addressing questions regarding their efficacy, storage, and potential benefits.

1. Understanding Silage Inoculants

   Silage inoculants are formulations containing beneficial microorganisms, such as lactic acid bacteria, that enhance the fermentation process during ensiling. They contribute to improved nutrient retention, reduced dry matter losses, and the prevention of spoilage.

2. Shelf Life and Storage

   Leftover silage inoculants can have a limited shelf life, and their effectiveness may diminish over time. Proper storage is crucial to maintain the viability of the microorganisms. Keep the inoculants in a cool, dark place and away from direct sunlight. Check the manufacturer’s guidelines for specific storage recommendations, as some inoculants may require refrigeration.

3. Testing Viability

   Before using leftover silage inoculants, conduct a viability test to assess the microbial activity. This can be done by culturing a small sample to determine if the desired microorganisms are still active. If the inoculant has lost its efficacy, using it may not provide the intended benefits during ensiling.

4. Mixing with Fresh Inoculants

   Combining leftover silage inoculants with fresh inoculants is a common practice. This hybrid approach can help maximize the microbial population and ensure the dominance of beneficial bacteria in the ensiling process. However, it’s essential to consider compatibility and avoid mixing different types of inoculants unless recommended by the manufacturer.

5. Targeting Specific Forages

   Certain forages may benefit from specific types of silage inoculants. If you have leftover inoculants designed for specific crops or conditions, consider using them for similar forages during the next ensiling season. Matching the inoculant to the forage type enhances its effectiveness.

6. Cost-Benefit Analysis

   Evaluate the cost-effectiveness of using leftover silage inoculants. If the cost of testing, storing, and mixing the inoculants outweighs the potential benefits, it may be more economical to invest in fresh inoculants for optimal ensiling outcomes.

7. Manufacturer Recommendations

   Always consult the manufacturer’s guidelines for using leftover silage inoculants. They may provide specific recommendations for testing viability, storage conditions, and compatibility with other products.

While using leftover silage inoculants is a practical approach to reduce waste and maximize resources, it requires careful consideration of factors such as shelf life, storage conditions, and compatibility. Conducting viability tests and following manufacturer recommendations are essential steps in ensuring that the inoculants contribute effectively to the ensiling process. By making informed decisions, dairy farmers can optimize the use of leftover silage inoculants and enhance the overall quality of their silage.

Mycotoxins are toxic substances produced by certain fungi that can contaminate various crops, including those commonly fed to dairy cows. The presence of mycotoxins in the feed can have detrimental effects on the health and productivity of dairy cattle. This article aims to provide an overview of mycotoxins, their sources, and the potential impact on dairy cows.

What are Mycotoxins?

Mycotoxins are secondary metabolites produced by molds such as Aspergillus, Fusarium, and Penicillium. These fungi can grow on crops both in the field and during storage, especially when conditions are conducive to fungal growth, such as high humidity and temperature fluctuations. The mycotoxins produced can persist through the processing of feed and ultimately end up in the rations fed to dairy cows.

Common Mycotoxins Affecting Dairy Cows

Several mycotoxins can affect dairy cattle, with some of the most prevalent ones being aflatoxins, deoxynivalenol (DON), zearalenone, ochratoxin A, and fumonisins. Each mycotoxin has specific toxic effects, and the severity of these effects depends on factors such as the concentration of the mycotoxin, duration of exposure, and the overall health of the animals.

Impact on Dairy Cow Health

1. Reduced Feed Intake: Mycotoxin-contaminated feed often has an unpalatable taste and odor, leading to a reduction in feed intake. This can result in poor nutrition and decreased milk production.
2. Immunosuppression: Some mycotoxins, such as aflatoxins and DON, can suppress the immune system, making cows more susceptible to diseases.
3. Reproductive Issues: Mycotoxins like zearalenone can cause reproductive problems in dairy cows, including infertility and abnormal estrous cycles.
4. Milk Contamination: Certain mycotoxins, like aflatoxins, can contaminate the milk produced by dairy cows. This poses a risk to both animal and human health, as these toxins can enter the human food chain.

Management Strategies

1. Feed Testing: Regularly testing feed for mycotoxin contamination is crucial. This allows farmers to identify contaminated batches and take corrective measures.
2. Quality Feed: Ensuring the quality of the feed by proper storage and handling practices can help minimize fungal growth and mycotoxin production.
3. Mycotoxin Binders: Including mycotoxin binders in the feed can help mitigate the negative effects of mycotoxins by binding to the toxins and preventing their absorption in the digestive system.
4. Diverse Feed Sources: Using a variety of feed sources can reduce the risk of mycotoxin exposure, as different crops may be susceptible to different types of fungi.

Understanding the impact of mycotoxins on dairy cows is essential for maintaining herd health and ensuring the production of safe and high-quality milk. Implementing effective management strategies and regularly monitoring feed for mycotoxin contamination are critical steps in mitigating the risks associated with these toxic substances. By prioritizing the health of dairy cows, farmers can safeguard both animal welfare and the economic sustainability of their operations.

Dairy calf nutrition plays a pivotal role in determining the future health and productivity of dairy cows. The traditional approach to calf rearing has focused on meeting immediate growth targets, but there is a growing recognition of the long-term benefits that come from a more holistic and nuanced approach to calf nutrition. This article explores the key aspects of re-evaluating dairy calf nutrition to ensure sustained well-being and enhanced productivity in the long run.

1. Early Life Nutrition: Setting the Foundation

   Early nutrition is critical for the development of a healthy and productive dairy cow. Providing colostrum rich in antibodies within the first few hours of life is essential for a strong immune system. Additionally, formulating a balanced milk replacer or transitioning to a well-balanced solid diet should be done with careful consideration of nutrient requirements to support optimal growth and development.

2. Transitioning to Solid Feed: Balancing Growth and Gut Health

   The transition from liquid to solid feed is a crucial phase in a calf’s life. Emphasizing a gradual weaning process and introducing high-quality forages and concentrates ensures a smooth transition while promoting rumen development. Balanced nutrition during this phase contributes to the resilience of the gastrointestinal tract and sets the stage for efficient nutrient utilization in later life.

3. Protein and Energy Balance: Optimizing Growth Without Compromising Health

   Striking the right balance between protein and energy is essential for calf growth. While protein is necessary for muscle development, an excess can lead to health issues. Similarly, maintaining an optimal energy balance supports growth without risking conditions like over-conditioning, which can have negative consequences on future milk production and reproduction.

4. Mineral and Vitamin Management: Supporting Overall Health

   Adequate mineral and vitamin intake is crucial for bone development, immune function, and overall health. Regular assessments of mineral content in feed and adjustments based on specific needs help prevent deficiencies or excesses that may compromise long-term health.

5. Gut Health and Microbiome: A Focus on Probiotics and Prebiotics

   Recognizing the importance of a healthy gut microbiome in dairy calves is gaining traction. Incorporating probiotics and prebiotics into the diet supports the development of a robust microbial community in the rumen, enhancing nutrient absorption and overall health. This approach has long-term implications for disease resistance and feed efficiency.

6. Long-Term Economic Considerations: Balancing Cost and Investment

   While optimizing calf nutrition may incur initial costs, the long-term economic benefits are substantial. Healthy, well-nourished calves are more likely to reach their production potential, reducing the need for veterinary interventions and improving the overall efficiency of the dairy operation.

Re-evaluating dairy calf nutrition involves a shift from short-term growth objectives to a more holistic and long-term perspective. By prioritizing early life nutrition, emphasizing a balanced transition to solid feed, and considering the interplay of protein, energy, minerals, and the microbiome, dairy farmers can set the stage for the sustained health and productivity of their herds. This approach not only contributes to the well-being of individual animals but also enhances the economic viability of dairy operations in the long run.

Calf barns or rooms may be ventilated either naturally or mechanically, with natural ventilation mixed with a positive pressure ventilation tube (PPVT) system offering the best of both. The four basic purposes of ventilation calf barns or rooms are to remove moisture in cold weather, heat in hot weather, deliver fresh air consistently, and prevent drafts.

Calves from birth to weaning need 17 m3/h (10 cfm) of fresh air per calf in the winter to remove moisture and 170 m3/h (100 cfm) in the summer to remove heat. However, the actual air exchange needed often exceeds the minimal ventilation needs. Calves need four room air changes per hour in winter and 40 or more in summer. The problem with calves is to give the minimal amount of winter ventilation required uniformly and without drafts.

Natural ventilation works effectively for the most of the year, but during cold weather, calves from birth to weaning do not generate enough heat to provide thermal buoyancy to pull air in through the curtains and out via chimney holes. When the temperature drops too low to offer a decent air pattern naturally, the sidewall curtains may be entirely closed, and a PVVT system can be employed to deliver the least quantity of fresh air.

A PPVT system comprises of a wall-mounted fan that circulates fresh outside air into the calf room or barn. The fan is connected to a distribution tube with evenly spaced perforations that spans the length of the room. The fan brings fresh air in from the outside, pressurizes the tube, and blows it out of each hole to disperse it equally across the room. The fan pressurizes the room, and air escapes via the natural ventilation system, which is commonly through chimneys or cracks around the curtains.

The air tube’s number of openings, size, and spacing are all tailored to fit the room’s geometry. Tubes must be placed to best suit the size and configuration of the space. The hole position and pattern must fit the geometry of the room and the pen configuration. Lightweight plastic may be used for ventilation tubes, however woven polyethylene tubes are more robust and retain their form better. PVC pipe may also be utilized, particularly for tiny duct diameters.

PPVT systems may operate all year to provide air circulation. In hot weather, they do not provide enough ventilation for cooling, but on still humid days with no breeze, they will continue to circulate air. In the summer, air should be spread uniformly, with an aim of 1.3 m/s (250 fpm) for cooling.

Furthermore, providing the correct habitat is simply one aspect in raising calves. Colostrum management, adequate nourishment, particularly in cold weather, and correct preventive health procedures are all critical.

Dairy farming has come a long way since 2008, according to the magazine. In 2017, the United States utilized 21% less land and 30% less water to produce milk than in 2008. Recent studies out of Australia have looked at the link between a calf’s early diet and its later resilience and health as it gets ready to join the milking herd.

Careful management of heat stress and other obstacles is part of the delicate balancing act involved in Weenen, South Africa’s high milk output. Dairy farmer Barry Schiever has increased organic carbon levels to keep his land healthy and productive after seeing overgrazing owing to ineffective management. When it comes to managing dairy herds, improving silage intake is crucial since it helps minimize the intake of silage dry matter, which is typically lower than the matching fresh crop. Forage management at its finest is possible with the help of a solid rapport with a dairy nutritionist.

Because they help keep dairy cows healthy and producing at their peak levels, trace minerals contribute to sustainability efforts. Reaching the required sustainability goals in animal nutrition will need a concerted effort from every link in the supply chain for dairy nutrition.

In the United Kingdom, net-zero on farms is all the rage, and the 2023 Dairy Show will be the place to hear about the advantages of this goal. Forty farms in Cornwall are set to cut their carbon footprint in half over the course of five years, with the remaining three farms expected to achieve emission elimination under a lottery-funded initiative.

The polled gene in dairy cattle has been a subject of significant interest in the agricultural community, offering potential advantages for both farmers and the animals themselves. The term “polled” refers to the absence of horns in cattle, and this trait is controlled by a specific gene. In this article, we will explore how the polled gene works in dairy cattle and its implications for the dairy farming industry.

Genetics of the Polled Trait:

The polled trait is inherited in a Mendelian fashion, meaning it is controlled by a single gene with two possible alleles – one for the presence of horns (H) and the other for the absence of horns (h). The polled gene is a dominant one, where the presence of at least one copy of the polled allele (h) results in the polled phenotype. Therefore, cattle can be either homozygous polled (hh) or heterozygous polled (Hh) to exhibit the polled trait.

Advantages of Polled Cattle:

1. Safety and Handling: One of the primary advantages of polled cattle is the enhanced safety during handling. Horned cattle can pose a risk to both farmers and other animals, as they may inadvertently cause injuries. Polled cattle eliminate this risk, making them easier to manage.
2. Reduced Aggression: Horned cattle may exhibit more aggressive behavior, especially during feeding or in confined spaces. Polled cattle tend to be less aggressive, contributing to a more harmonious and stress-free environment on the farm.
3. Space Efficiency: Horned cattle may require more space to prevent injuries due to horn clashes. The absence of horns in polled cattle allows for more efficient use of space within barns and feeding areas.

Breeding Strategies:

To propagate the polled trait in a cattle herd, farmers can adopt specific breeding strategies. By selectively mating polled individuals or carriers of the polled allele (Hh) with other polled cattle, farmers can increase the prevalence of the polled gene in subsequent generations. Genetic testing can be employed to identify carriers and ensure informed breeding decisions.

Challenges and Considerations:

While the polled trait offers numerous benefits, it is essential for farmers to consider other traits relevant to dairy production, such as milk yield, reproductive performance, and overall health. Balancing the selection for the polled trait with the maintenance of desirable production characteristics is crucial for sustainable and profitable dairy farming.

The polled gene in dairy cattle represents a valuable tool for farmers seeking to enhance safety, efficiency, and overall management on their farms. Through careful breeding strategies and the incorporation of genetic testing, the polled trait can be selectively propagated to create a herd of cattle that combines both desirable production traits and the polled advantage. As advancements in genetic research continue, the dairy industry can look forward to further improvements in breeding practices and the overall well-being of cattle.

The beef-on-dairy revolution has become a significant profit stream for dairy farmers across the country, as milk prices continue to sink. Since 2018, there has been a significant shift with beef-on-dairy crossbreds, with over 3.25 to 3.5 million head of these animals coming through as crossbreds. This proportion has grown tremendously within the last few years, and it is estimated that almost 23% of the total number of fed steers and heifers within the U.S. are actually coming from dairies.

The reason for this recent spike is due to widespread drought across the mid- and southwest, which has shrunk the beef cow herd significantly. However, with more and more dairies relying on beef-on-dairy calves to help turn a profit, these operations have helped fill the meat cases. The dairy segment of the beef industry has grown in significance the last few years even more so than it had traditionally.

As more dairy crossbreds make their way into the marketing chain, researchers have closely examined the characteristics of these animals and the products they yield, compared to their full-blood dairy and beef cousins. Their findings regarding major performance and carcass data include feedlot growth, quality grade, carcass yield, eating quality, meat color, muscle shape, consistency, and traceability.

Feedlot growth shows that the average daily gain and feed-to-gain ratio of crossbreds is significantly better than Holsteins and similar to conventional beef cattle. Quality grade indicates that crossbreds produce the same amount of beef in a shorter timeframe and on less total feed. Crossbreds also have a lower dressing percentage than full-blood beef animals, at least partly because they are leaner and thus have lighter carcasses relative to their live weight.

Eating quality shows that full-blood Holsteins still take first place in terms of tenderness, followed by crossbreds and then conventional beef. Crossbred longissimus (loin) muscles are larger and rounder than Holsteins, and consumers can not distinguish their shape compared to those from conventional beef cattle.

Consistency is another key factor in the success of dairy cattle. Dairy animals produce a consistent supply of offspring year-round, which helps improve market stability. Today’s dairy cattle are highly consistent genetically, creating potential for excellent offspring consistency with correct sire matings.

Dairy producers and veterinarians can confidently implement mastitis treatment protocols against mastitis cases caused by Gram-negative bacteria with Spectramast^® LC (ceftiofur hydrochloride) Sterile Suspension from Zoetis. Research from the University of California, Davis — published online in the Journal of Dairy Science (published in press Nov. 2, 2023) — showed that treatment of nonsevere (mild and moderate) cases of clinical mastitis caused by Gram-negative bacteria with Spectramast LC was effective in improving bacteriological and clinical cures, lowering mastitis recurrence, reducing use of supplemental therapy and minimizing mastitis-related culls and deaths.¹

Conducted on three large dairy herds in California and using 415 nonsevere clinical mastitis cases caused by Gram-negative bacteria, the clinical trial compared outcomes between cows that received two-day intramammary treatment with Spectramast LC and cows that received no treatment. Results showed the effectiveness of two-day treatments with Spectramast LC was better than not treating. Specific findings from the research included:

• 24.7% increase in bacteriological cures in treated groups at Day 14 compared with untreated groups¹ 
• 46.8% reduction in mastitis-related cull and death rates in treated groups compared with untreated groups¹ 
• $204-per-head reduction of mastitis-related losses in groups treated for two days compared with untreated groups¹

“Early intramammary treatment of Gram-negative mastitis infections with Spectramast LC provides significant benefits compared with the option of not treating and assuming that cows would self-cure without consequence,” said Dr. Daniela Bruno, DVM, PhD, Dairy Advisor for University of California, Davis.

A prudent strategy would be to treat all cases of Gram-negative mastitis with Spectramast LC, and not attempt to distinguish mild cases from moderate cases, the research suggested.

“A case of non-severe Gram-negative mastitis has the potential to become a severe infection that requires more aggressive treatment, adding costs and delaying return to productivity,” said Juan Pedraza, DVM, Managing Veterinarian of Zoetis Dairy Technical Services. “Based on the research, you’re looking at improved cure rates, lower treatment costs due to the reduction in use of supplemental therapy, and most importantly, helping keep cows healthy and productive members of the herd.”

The dairy industry recognizes mastitis as one of the costliest disease conditions that dairy producers must manage. Gram-negative bacteria alone, especially coliforms like E. coli, Klebsiella spp., or Enterobacter spp., can pose a real threat to herd productivity, causing up to 35 percent of all intramammary infections on dairies.^2,3 In one study, 66 percent of cultured samples initially tested negative but 34 percent actually were positive for a Gram-negative pathogen.³ Gram-negative bacteria can be elusive so it’s important to evaluate what an appropriate treatment protocol could look like for Gram-negative mastitis cases to help improve cow wellness outcomes and mastitis-treatment-related costs for the dairy industry.

“We continue to invest in new, practical on-label solutions and support research that will advance mastitis management protocols so veterinarians, producers and parlor employees can use them with confidence,” said Dr. Pedraza.

Spectramast LC offers extended therapy as its unique, flexible label for at least two and up to eight days to achieve a bacteriological cure for a broad spectrum of bacteria. In addition, the two-day pre-slaughter meat withdrawal for Spectramast LC is the shortest withhold time available, providing more options for greater management flexibility. Milk withdrawal time is 72 hours after the last treatment, regardless of how many days treatments are administered (2-8 days).

Study on Social Housing in Dairy Calves

• A study by Marina von Keyserlingk of The University of British Columbia focuses on the impact of paired housing on the social competition skills of pre-weaning dairy calves.
• The research involved 18 3-week old bull and heifer calves divided into individual or pair housing at 11 days of age.
• The calves were tested to control for the influence of naturally bold personalities on their competitive abilities.
• After 5 days of testing, the results showed that pair-housed calves spent more time drinking from the bottle and were faster to approach the milk than individually housed calves.
• The University of Florida’s Department of Animal Sciences also examined how group housing impacts dairy calf personality traits.
• The study found that calves housed in pairs were bolder compared to calves individually before grouping, suggesting early-life social contact can influence personality traits in group-housed calves.

Recent studies have shown that early social housing can build behavioral skills, shape calf personalities, and set up animals for success in the herd. Personality is of growing interest in dairy cattle as it may be associated with outcomes related to an animal’s performance and welfare, including feeding behavior, weight gain for calves, and milk production in adults. A new study led by Marina von Keyserlingk of The University of British Columbia focused on how paired housing might impact the social competition skills of pre-weaning dairy calves. The research team looked at 18 3-week old bull and heifer calves divided equally into individual or pair housing at 11 days of age. After identifying their personalities, calves from each housing group were paired together for a competition over a single milk bottle. The results showed that pair-housed calves spent on average more time drinking from the bottle and were faster to approach the milk than individually housed calves. The second study at the University of Florida examined how group housing impacts dairy calf personality traits. The team found that calves housed in pairs were bolder compared to calves individually before grouping, suggesting that early-life social contact does have the potential to influence personality traits in group-housed calves.
