Latest Episode

Diving into Diets: Grazing Behavior

On this week’s episode of Diving into Diets Dr. Brad White and Dr. Philip Lancaster discuss a 2025 study on grazing behavior in cattle, focusing on factors like age, size, hide color, and forage quality. The study tracked 40 cows using GPS collars over three years, finding that older cows traveled further distances, possibly due to learning topography. Red cows traveled more in cold temperatures due to better heat retention from black hides. The study also noted that cows traveled further to high-quality forage areas, as measured by NDVI and IRG, and up slopes and to water sources. The study’s individual hypothesis testing approach limited the interpretation of confounding variables like production stage and weather.

About the Abstract: Antimicrobial Metaphylaxis Study

In About the Abstract, the experts discuss a study by Cordial and Carrie (2024) in the Journal of Animal Science, which compared the impact of metaphylaxis with Tulathromycin versus saline on high-risk beef stocker calves over 42 days. The study found that calves treated with Tulathromycin had higher average daily gain, especially in the first 14 days, and fewer treatments for respiratory disease. Culture results showed more bacteria in saline-treated calves at follow-up. Antimicrobial use was higher in the Tulathromycin group, but the number of regimens was similar. The study suggests that metaphylaxis may improve health and performance while managing antimicrobial resistance. Featured Article: https://pubmed.ncbi.nlm.nih.gov/38126883

Guest Dr. Cassandra Olds: What is Theileria, How is Theileria Transmitted, Heifer Development

In this episode of BCI Cattle Chat, guest Dr. Cassandra Olds continues the discussion of Theileria, a tick- and fly-borne parasite affecting U.S. cattle herds. The team explains how it spreads from the East Coast westward, causes anemia-like symptoms, and persists for life in infected animals. They stress prevention through stress reduction, parasite control, and good nutrition, noting that no approved treatment exists. The conversation shifts to preparing heifers for breeding season, emphasizing pre-breeding exams, tracking weight and reproductive readiness, and managing nutrition to ensure early conception and lifelong productivity.
