In this episode of Cattle Chat, Dr. Brad White and the team welcome graduate student Katherine Shirley, who discusses her summer research on heat stress and cardiopulmonary issues in feedyard cattle. She explains how environmental factors like temperature, humidity, and hide color can influence cattle health and mortality. The crew then answers a listener’s question about pregnancy checking, covering ideal timing, methods, and the causes of early pregnancy loss. Finally, Cameron Best from Australia joins to compare U.S. and Australian cattle production, highlighting differences in climate, forage systems, and market structures.

In this week’s episode of Cattle Chat, Bob Weaber interviews Dr. Stephan Hughes, a veterinarian from South Africa, while on a trip. Hughes shares how he started listening to Cattle Chat and how beef production differs in South Africa. They also talk about the different tools Kansas State University has that can enhance your operation, not only in the United States but also abroad. The team then transitions to a listener question about bull fertility. The experts emphasize the importance of testing your bull’s fertility, especially as he ages.

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.

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.

On Cattle Chat this week, Dr. Bob Larson, representing the Academy of Veterinary Consultants (AVC), and guest Dr. Fred Gingrich, with the American Association of Bovine Practitioners (AABP), discuss the work their organizations are doing. Anaplasmosis is also discussed, highlighting its transmission by ticks, the limitations of current control methods, and the importance of early veterinary intervention to manage the disease.

In this week’s episode of Cattle Chat, the experts discuss the evolution in the feedlot industry. They debate how producers used to calculate cost based on feed efficiency. The team also questions different cow-calf practices. Lastly, they debate whether or not you should have bigger cows with heavier weaned weight for your calves or if you should have smaller cows so there are more cows per acre, resulting in more calves being sold.

On Cattle Chat this week, the experts discuss whether or not you could be taking records, making a plan, or both when it comes to your breeding season. After the discussion, the team talks about implementing your plan. When making your plan, what should you be looking for when saving back replacement heifers? They talk about how much age should play a factor when saving back your replacement heifers
