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.
