Bovine Rotavirus-Coronavirus Vaccine, Clostridial C & D and E. coli vaccine
The most complete neonatal diarrhea (scours) vaccine available.
BOVILIS GUARDIAN offers the broadest spectrum of antigens associated with major bacterial and viral causes of scours in young calves including rotavirus types G6, coronavirus, Clostridium perfringens types C & D, and Escherichia coli type K99.
This product has been shown to be effective for the vaccination of healthy pregnant cattle to provide passive immunity against neonatal calf diarrhea due to bovine Group A Serotype rotaviruses, enterotoxigenic E. coli pilus type K99, and bovine coronavirus, and enterotoxemia due to C. perfringens Types C & D in calves. Duration of immunity has not been established.
Passive immunity against neonatal calf diarrhea due to:
Importance Of Scours Prevention
Scours can have a detrimental impact on the health and performance of calves. Anytime the intestinal tract is damaged, absorption is affected and performance impaired.
Vaccination timing for pregnant cows is critical to stimulating and optimizing antibodies in colostrum. If cows are vaccinated too early the antibody response may start to fall off prior to the colostrum being made. Vaccinating too late and the colostrum may be made before an antibody response is mounted.
Colostrum Regime Important To Maximize Antibody Transfer
Colostrum intake within the first 12 hours of a calf’s life is important for it to receive the necessary antibodies to fight scours-causing pathogens. Ideally, a calf will get 2 quarts of colostrum within 2 hours after birth and another 2 quarts within 6 hours after birth for the best antibody absorption.
In addition, it’s important to maintain a clean, open environment and reduce crowding and wet areas because they can lead to increased calf stress and exposure to disease agents.
Shake well and administer a single 2 mL vaccination dose by subcutaneous route to pregnant cattle 3 months prior to calving and a single 2 mL booster dose 3 – 6 weeks following initial vaccination. For subsequent calvings, revaccinate with a single 2 mL dose 5 – 7 weeks prior to calving.
