For decades, estradiol-based protocols have been central to fixed-time artificial insemination in beef cattle, but growing scrutiny of estrogenic compounds has prompted researchers to explore alternatives. In this episode, Dr. Jaswant Singh and Dr. Carlos Leonardi discuss their research on Cetrorelix, a human fertility drug that may offer a non-steroidal approach to follicular wave synchronization.

Behind every new technology, diagnostic tool, protocol or technique in cattle health is a real-world problem that someone set out to solve. The Bovine Vet Podcast talks with the veterinarians, researchers and industry professionals putting these innovations to work to improve outcomes in the field. The best tools are those that help make the best decisions for clients and their cattle.

A New Frontier in Cattle Synchronization

Join Dr. John Kastelic, professor emeritus of theriogenology at the University of Calgary, for a deep dive into the science and practice of bull fertility. From breeding soundness exams and ultrasonography to heat stress, early-life nutrition and emerging technologies, Kastelic shares practical insights gained over decades of research and clinical experience. Learn what today's BSE can — and can't — tell you, how new diagnostic tools are changing fertility evaluation, and why a bull's reproductive potential begins long before breeding season.

The Bovine Vet Podcast: Beyond the Breeding Soundness Exam

Bovine respiratory disease remains one of the biggest health challenges facing the cattle industry, despite decades of research and advances in prevention and treatment. In this episode, Dr. Paige Schmidt-Rios and Dr. Melissa Cantor explore both sides of the equation. Dr. Schmidt-Rios shares practical insights into diagnosing and treating BRD in today's feedlots, while Dr. Cantor discusses development of the CalfHealth system, an innovative research project using behavior monitoring and artificial intelligence to identify calves before clinical signs appear. Together, they examine where BRD management stands today and where new technology could take it next.

The Bovine Vet Podcast: The Future of BRD Detection

New World screwworm has been detected in the United States, creating new challenges for veterinarians and livestock producers. In this special episode, Dr. Diane Kitchen, state epidemiologist for the Florida Department of Agriculture and Consumer Services, discusses what practitioners should know about identifying suspect cases, collecting diagnostic samples, treating affected animals and supporting eradication efforts. She also explains current movement restrictions, reporting expectations and why daily animal observation remains one of the most important tools in the response.
