Trichomoniasis in Beef Cattle

Jun 29, 2023

Bovine trichomoniasis can be costly for beef cattle operations that use natural service. The disease can be found worldwide. It causes extended breeding seasons and diminished calf crops. Infection can be costly to treat, and its prevention is critical to the health of your breeding animals.

Trichomoniasis (often called “trich”) is a true venereal disease caused by a protozoan organism called Tritrichomonas foetus. It is spread through sexual contact. Adding infected bulls or cows into your herd is the most common source of introduction. Exposure to the neighbor’s bulls through a fence break or common grazing can also be a source of infection.

Video: Methionine Requirements for Lactating Sows - Cierra Kozole

In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
