Guest: Dr. Cassandra Olds, Theileria, Theileria Transmission, Winter Feeding Strategies

This episode of Cattle Chat features guest Dr. Cassandra Olds, an entomologist, who shares with the group about her research on Theileria, an emerging protozoan parasite in cattle. Dr. Olds explains that Theileria is tick‑borne but can also be spread by sucking lice, possibly stable flies, limited placental transmission, and contaminated needles or equipment, emphasizing single‑needle use and the difficulty of vector control. The conversation then shifts to winter hay feeding strategy: estimating cow weights and forage intake, testing hay quality, minimizing waste, cleaning up old hay to reduce stable fly breeding sites, and tracking bale disappearance over time to adjust feeding and prevent cows from losing condition. 4:11 Theileria 5:25 Theileria Transmission 17:01 Winter Feeding Strategies For more on BCI Cattle Chat, follow us on X at @ksubci, Facebook, and Instagram at @ksubci.
