Calving Challenges, Vaccination Decisions, and Managing Liver Flukes in Cattle

Posted on by

On this episode of BCI Cattle Chat, the experts cover listener questions on calving difficulty, vaccination strategies, and liver fluke management. The team discusses that while malpresentation in calves can sometimes occur in clusters, it is more strongly linked to factors such as calf size, twins, and genetics than to cattle handling, though low-stress handling remains important. They also discuss vaccination protocols for incoming calves, emphasizing that vaccines are a long-term preventive tool and should be paired with strong overall health management. Finally, they highlight that effective liver fluke control depends on understanding the parasite’s life cycle and managing environmental risk factors, not just treatment.

U.S. Beef Imports and Brucellosis

Posted on by

In this episode of BCI Cattle Chat, the team discusses beef imports and brucellosis in the cattle industry. The experts explain that the U.S. imports lean beef to complement domestic production, especially for ground beef, while exporting other cuts, such as liver and tongue, helping balance supply and meet consumer demand. They also review brucellosis, a bacterial disease that affects reproduction and can spread to humans, which has been largely controlled through vaccination and eradication programs. However, the disease still exists in wildlife near Yellowstone, making proper vaccination and management practices important for prevention.

Herd Health: Modified Live Vaccines at Synchronization

Posted on by

In this episode of Herd Health, the experts review a 2025 study evaluating whether modified live virus (MLV) vaccines can be given at the time of CIDR placement for timed AI in beef cows. In previously vaccinated, multiparous cows about 80 days postpartum, administering an MLV vaccine at synchronization did not negatively affect estrus response, AI pregnancy rates, overall pregnancy rates, pregnancy loss, calving timing, or calf weaning weights. Total pregnancy rates were around 95%, with no significant differences between vaccinated and control groups. The findings suggest that giving an MLV vaccine at synchronization is safe in well-vaccinated adult cows, though results may not apply to naïve heifers.
