The microbiological revolution is improving forage quality and cow health. Chloe Palmer attends an event hosted by EnviroSystems to hear how soil biology is the essential ingredient.
Ensuring the soil can support a strong biological component is key to high quality forage and a healthy cow, farmers heard at an event in Staffordshire.
“You are what you eat and it is the same for a cow,” says David Lievesley, who along with James and Jonathan Pickford, runs Picston Holsteins at Spot Acre Farm, near Stone, Staffordshire.
Mr Lievesley was joined by David Law, managing director of the New Zealand-based Forward Farming Biological Consultancy, and both explained how they believe many of the disease problems seen in the modern dairy cow are linked to deficiencies in the soil, passing through to forage.
“All cows are built on calcium and we send a tank of calcium off the farm each day. What are we doing to put it back?” Mr Lievesley asked.
Mr Leivesley pointed to cows giving more than 10,000 litres each year and whenever they are stressed, they will take calcium from their metabolism.
Calcified
“If the forage passing through the rumen is not calcified, the cow cannot buffer herself. If the forage comes from a soil with a lower pH and a lack of calcium, its composition will reflect this because you will never make an alkaline forage from an acidic soil.
“We are seeing replacement rates in dairy herds now in excess of 30 per cent and this is not acceptable. Some of the causes of this can be traced back to the soil,” Mr Lievesley said.
Pointing to a clamp of 2016 silage, Mr Lievesley described the characteristics of a good crop of silage.
“When compressing silage in the hand it should spring back because this is what it will do in the cow’s rumen. It should be reasonably dry and should contain plenty of fibre to provide the springiness.
“When cows are chewing cud from slushy silage, they will froth at the mouth and this is because they are trying to buffer themselves because the silage is acidic.”
Mr Lievesley highlighted the 14kg dry matter from silage which cows should be consuming each day and this should give them 70 per cent of the nutrients and minerals they need.
At Spot Acre Farm, the grass silage is supplemented with home-grown wholecrop oats, lucerne and red clover, but the soil they are produced from strongly influences the feed content of these feedstuffs, Mr Lievesley said.
“The calcium to magnesium ratio is critical and if this is wrong, this is where the problems start, especially in wet years. If the ratio is correct, the silage will retain its protein content and it will not be lost in the fermentation process.”
Lactic acid
“Lactic acid will make silage but it will not run a cow. If the silage contains too much lactic acid, it will reach the muscular system and adversely affect locomotion,” Mr Lievesley said.
Mr Lievesley describes the ‘open coated cows’ he observes suffering weight loss at turnout and said this reflects a diet in ‘an unstable state’.
“Calcium is the principle cation in the soil and if in the right ratio with magnesium it will ensure the minerals needed by the cow are made available to the plant it eats. It is the ‘trucker’ in the soil and boron is the steering wheel.”
“Cows need iodine for fertility and they require selenium to form white muscle tissue around the heart and the pelvic girdle to help to prevent retained cleansings. The selenium, along with zinc also supports their immune system,” Mr Lievesley said.
Mr Lievesley urged farmers in the audience to have a comprehensive soil analysis to include the 16 trace elements necessary for the healthy functioning of the cow. He said: “I look at a soil sample and I interpret it in terms of what it means for the cow. Many of the immune suppressive diseases cows are now suffering from are caused by a deficient diet. We should be sourcing natural probiotics from the soil rather than fighting these diseases with antibiotics.”
The content of the slurry produced by the cows is linked to the diet and the soil according to David Laws and he examines slurry lagoons, or ‘ponds’ as they are called in NZ to appraise the overall health of the system.
He said: “I look at the end of the system to find out the answers to the rest of it. Where you have a thick crust on the pond, it is the undigested feed, the fibre. If the slurry has a low pH, I know the soil growing the forage has a low pH.“If a thick crust forms on the slurry, the bugs are not working because they are not breaking it down. I recommend farmers add lime to these ponds just as they would their soil to help the bugs and this will go all the way through the system.”

A farm expansion planner says it takes time to properly go from concept to completion. Emily Schmidt of Miller Engineers & Scientists in Sheboygan, Wisconsin helps farmers with the expansion process and says there are two time-consuming steps. “If you take the 90-days in just for the permitting process plus the time to design, I mean we usually look into a month to six months in advance before we want to break ground.”
Since the new year, I have travelled to many dairy farms across Western Canada and conducted a personal survey about lameness in dairy cattle. At each visit, I asked producers “What was their biggest cause of hoof problems?” Almost unanimously, their answer was “hairy heel warts!” This is no surprise, since multiple surveys conducted over the last few decades, mapped its spread across North American dairy farms. Fortunately, early detection, constant vigilance and prevention is the key to controlling this major hoof disease.
If you think your heifer reproduction program is on track, you may want to look again. Conception rate and percentage of heifers pregnant within three services are metrics commonly used to track performance of heifer reproduction.
Oregon has 228 family dairy farms, ranging from fewer than 100 cows being milked each day to more than 30,000. Regardless of the size of the farm, there are certain values, standards and management practices that every Oregon dairy farmer has in common.






Spring is in the air, and while spring-cleaning typically means deep cleaning your house, your dairy could benefit from some sprucing up, too. Whether it’s milking protocols, curtain maintenance or fine-turning vaccination programs, it’s important that no areas are missed so you can reach your Dairy Wellness goals and improve profitability. 


A spike in empty cow rates shows how easily nature can expose flaws in dairying best practice, says a Waikato vet.
Japanese telecommunications giant NTT Docomo will launch an internet-linked monitoring service later this month that will help farmers better determine whether a cow is in heat.
Dairy producers in the United States are feeling the stress of volatile markets, increasing regulation and consumer demands. During stressful times, it can be easy to let emotions overtake rational thinking, which often leads to poor decision making. Dr. Chris Canale, Cargill U.S. dairy technology manager, offers these tips to ‘hold the line’ when it comes to making decisions:
Dairymen who use the right feed at the right time can maintain profitability even in down times, says Mike Hutjens.
A consultant says there are benefits to expanding dairy farms during times of low milk prices.
Dairymen who use the right feed at the right time can maintain profitability even in down times, says Mike Hutjens.


One third of the cows is not making it in their barns. Why? Because of diseases, and one in particular. Subclinical rumen acidosis is barely visible, but will weaken you cows, leading to other diseases. In the end, this is cutting cow lives short. If we want to do something about this, we need to broaden our knowledge of feed. There’s plenty of information about feed quality available, but more knowledge of housing and management with regard to feeding is much needed.
Shocking numbers and there’s plenty to say about each disease individually. But let’s look at one disease in particular: rumen acidosis. This disease is hard to recognize for farmers, but will seriously weaken the cow. It starts with nausea and by the time you catch it (or not), the other trouble has already started: mastitis, lameness, low fertility rates and so on. This is what in the end is keeping cows from happily and healthy making it to five lactations.
So if you can hardly catch it in time, it is even more crucial to prevent it. For prevention farmers need a good understanding of how the rumen functions and an excellent feeding program. A major issue is feed quality and luckily, most farmers have a good feed advisor for this. What the feed advisor often doesn’t tell the farmer is how management and housing effect feed intake. Without broadening knowledge about feeding to these areas as well, rumen acidosis just will keep happening.
In summary, rumen acidosis is a very serious disease that has enormous effects on both the cow’s as the farmer’s life. Good farmers will actively search for new insights and improvement opportunities in the housing and management department. Good advisors, that are keen on giving quality advice and creating a sustainable relationship with their clients by constantly being of added value, face the challenge to give advice on a broader scope and involve all factors needed for a good feeding program. This will not only benefit cows and farmers, but also the farm advisor. Together, we can do a better job.

U.S. dairy producers work hard every day to provide the safest food in the world to consumers, but there is always room for improvement. Although dairy cattle make up less than one tenth of the total cattle sent to market, dairy and bob veal from dairy account for 90% of the violative residues on an annual basis. Just one single residue violation can erode consumer confidence and a dairy operation’s reputation.
Reviewing the numbers probably isn’t the most exciting thing at your dairy farm. But if you want to be around next year, and the year after, you better know where you stand.
Millennials, those born after 1982, will soon make-up 50% of the workforce. This generation, often misunderstood and identified as being lazy, was raised on grading rubrics. Every performance expectation and academic milestone was carefully spelled out, clearly outlining the necessary steps to achieve an ‘A’ or just get by with a ‘D’. When millennials fell short, a parent, teacher, or mentor coached them to success.
The maternity pen is a calf’s first contact with her environment, and what the calf is exposed to can make or break her future in your dairy herd. That’s why maternity pen management needs to be a high priority on your dairy. Here are some opportunities for you to help get your calves off to a healthy start.
Additional perspective on debt can be obtained by analyzing farm level data from FBFM. Table 1 presents average data for grain farms enrolled in FBFM who have certified-useable balance sheets. The data is stated in nominal terms and debt levels are stated as of year-end 1991 through 2015. Three measures of debt level are presented in Table 1: debt-to-asset ratio, debt per tillable acre, and interest expense per tillable acre.
The dairy industry organisation ran a Milk Smart seminar near Palmerston North at a dairy farm, and about 20 people went to find out more about cow senses.
The youngest animals on a dairy are often the most vulnerable. Improving mortality rates in this susceptible population can be the key to decreasing costs and improving productivity.
When the feed bunk is overstocked it can have negative impacts on profits.
A violative residue is a residue that is above the maximum residue limit (MRL) of 300 ppb for tetracycline. From this University of Minnesota research, we know that applying 2 grams or less of tetracycline powder per lesion for a maximum of two lesions per cow will not cause violative residues in individual cows and is enough to successfully treat the lesion (Figure 1). A complicating factor is that although the MRL is 300 ppb, some of the tests used to screen milk can detect tetracycline residues at a much lower level. What you and your veterinarian will need to consider is how your milk processor is going to implement the NICMS pilot program and how they will use the results of tests that find tetracycline residues below the MRL. In most cases, if an appropriate dose of tetracycline is used on individual animals, the risk of contaminating the food supply with violative residues is minimal. However, in some cases, your veterinarian might be uncomfortable with the risk of potentially contaminating the milk supply and include a milk withdrawal period.
