This week, Dr. Nathan Erickson and Dr. John Ellis join me to discuss the emergence of Bovine influenza A virus in cattle. We discuss what is currently known about this emerging disease issue at this point in time. New information is being acquired about the impacts and spread of Bovine Influenza A virus and this podcast gives information on the disease as known around April 12, 2024. Please rely on your local veterinarians or government veterinary offices for the most up to date information on this issue. Emerging diseases remind us of the importance of preventive practices. Using raw colostrum only from your own herd, not introducing orphan calves or nurse cows from dairy herds and quarantining new animals for 21 days will help prevent the introduction of diseases like Bovine Influenza A virus, Foot and Mouth Disease, and many other diseases.
