Keep the Cow and Her Future Calf Protected


Using killed vaccines during the dry period can help the cow and her calf fight off disease.

When it comes to killed dry cow vaccinations, you’re not only vaccinating for the health of the cow, you’re also providing future protection for the vulnerable calf. Killed vaccines, safely administered at the beginning of the dry cow period, can help keep the dam healthy and enhance the antibody levels found in the colostrum.1

Protection for the Calf

Calves are not born with antibodies, so they must receive them from the colostrum they get at birth. Boosting the antibodies in the colostrum through vaccination has both short- and long-term payoffs. “Immediately, that calf receives protection against the common viral and bacterial infections that are in its environment,” said Mark van der List, DVM, Boehringer Ingelheim. “Calves with successful passive transfer are less likely to develop scours or pneumonia, and are at a reduced risk of mortality.”

To ensure the newborn calf receives maximum benefits, it is recommended to collect the colostrum from the dam and feed to the calf as soon as possible. As the hours pass after calving, the colostrum can be diluted with regular milk, which can lower the concentration of antibodies.

Protection for the Cow

The fresh period is often a time of stress for cows. It can challenge their immune system and leave them susceptible to disease. By vaccinating cows during the dry period, they are more likely to enter the next lactation period with a robust immune system to fight off infectious disease threats. Killed vaccines are an especially safe option for pregnant cows if their health and vaccination histories are unknown. A cow given a modified-live virus (MLV) vaccine that has not been properly immunized with prior vaccinations may abort.

Choosing the Right Vaccination Protocol for Your Herd

“If you decide to incorporate a killed vaccine into your protocol, make sure the one you choose is flexible and provides proven protection against bovine viral diarrhea virus Types 1 and 2, infectious bovine rhinotracheitis, bovine respiratory syncytial virus and parainfluenza 3,” remarked Dr. van der List.

When using killed vaccines for the first time, it’s important to give two doses of the vaccine according to label directions. Failure to give a second dose within the correct time frame is a common reason a killed vaccine can fail.1

“Producers should also incorporate a clostridial vaccine,” Dr. van der List asserted. “Clostridial spores thrive on dairy operations, and without vaccination, problems with blackleg or malignant edema could arise in cows with tissue injury from calving and calves can suffer from enterotoxemia. Your veterinarian may also recommend leptospirosis vaccination.” If scours have been an issue on your dairy, consider vaccinating the cows with a scour vaccine to make sure the calf receives those antibodies in the colostrum.

Protection Beyond Vaccination

“It’s important to remember that it takes more than vaccination to keep calves and cows healthy,” stressed Dr. van der List. “In order for a cow’s immune system to respond optimally to vaccination at dry off, a cow must have a good transition period. During that time, proper nutrition, cow comfort and low stress will deliver a much healthier cow and calf.”

Dr. van der List encourages producers to work with their veterinarian for guidance. A dry cow vaccination protocol will vary with management of the farm. “Review your cow and calf health protocols with your veterinarian every year to ensure they’re current and you’re covered for the challenges specific to your environment,” he concluded.
