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

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

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.

Research Update: Liliana Rivas and Cow Efficiency

On this week’s BCI Cattle Chat episode, graduate student Liliana Rivas updates us on her research about leaky guts in yearling calves. She conducted this by feeding the calves a restricted diet and measuring indigestible sugars in the bloodstream over 36 hours. The experts also discussed cow efficiency, measured as pounds of calf weaned per pound of feed consumed per cow exposed. A key finding was that the nutrition models in the study underestimated the extent to which energy restriction harms reproduction.

Managing Body Conditioning in Cows, Cause and Management of Weak Calves

The experts discussed whether it is more costly to have thin or fat cows going into the calving season. Thin cows are generally more costly because they are at high risk of having calving issues. Determining when to be aggressive with supplementation is important when addressing thin cows. The team also answered a listener’s question regarding weak calves. They discussed the factors that could be causing the calves to be weak. The key takeaway is that weak calves are associated with long or difficult births, weather stress, and poor nutrition. Better monitoring of heifers and calving progress can prevent many issues.
