As the seasons change, calves can face increased health challenges. Dr. Ryan Breuer, Clinical Assistant Professor and Diagnostic Case & Outreach Coordinator at the University of Wisconsin School of Veterinary Medicine, emphasizes the importance of maintaining vigilant health practices for young calves.

“Calf issues occur year-round, but seasonal changes often bring an increase in disease processes,” Dr. Breuer explains. “Respiratory diseases and other common illnesses, like Salmonella, are more prevalent when the weather fluctuates.”

As farmers prepare for the colder months, Dr. Breuer encourages them to assess their management protocols. "The environment, the pathogen load, and the calf’s health are all factors in preventing disease," he explains. "By paying attention to these areas, farmers can ensure healthier calves and a smoother transition into winter."

Dr. Breuer also reminds farmers of the critical role of colostrum in calf health. "The quality, not the quantity, of colostrum is vital. Ensuring that calves receive enough colostrum with a high level of immunoglobulins is essential for their early health," he explained.
