Description
This five-session course provides a comprehensive framework for understanding and applying estrus synchronization strategies in beef cattle. Designed for veterinarians, producers, and allied industry professionals, the course builds from physiological foundations to practical application of protocols in heifers, cows, and embryo transfer recipients. Each session combines research-based knowledge with field-tested techniques to support improved conception rates, tighter calving windows, and long-term herd profitability.
Participants will explore key management considerations including hormone function, postpartum cyclicity, heifer selection, protocol compliance, and data interpretation. Sessions emphasize decision-making based on herd goals and real-world conditions, helping participants troubleshoot issues and optimize reproductive performance. The program is offered as a five-part online series. One hour of CE credit will be awarded for each completed session. Participants can attend individual sessions based on their interests and needs, earning CE credit accordingly.
Session 1: Physiological Principles that Underlie Estrus Synchronization Protocols
This session introduces the physiological basis of estrous synchronization in beef cattle. Participants will learn how the hormonal cycle supports pregnancy establishment and how synchronization protocols are designed to mimic this process. The session includes guidance on hormone timing, variation in estrus and ovulation, and troubleshooting synchronization failures.
Session 2: Control of Estrus and Ovulation in Beef Heifers
Focused on synchronization protocols for beef heifers, this session compares MGA and CIDR-based approaches, and reviews how reproductive tract scores and pelvic measurements can guide protocol selection. It also addresses unique considerations for Bos indicus-influenced heifers and explores research on split-time artificial insemination.
Session 3: Synchronization Protocols for Beef Cows
This session covers synchronization strategies for postpartum cows and their role in broader herd reproductive goals. Topics include managing postpartum cyclicity, selecting effective protocols like 7&7 Synch, and understanding how synchronization contributes to more uniform calving and increased calf value.
Session 4: Estrus Synchronization Programs for Recipient Females Prior to Embryo Transfer
Participants will learn how to synchronize recipient cows and heifers for embryo transfer. The session highlights the importance of matching embryo stage with recipient status, compares outcomes with fresh, frozen, and IVF embryos, and outlines key cow-level factors that influence success.
Session 5: Assessing Synchronization Programs: Goals and Troubleshooting Results
The final session focuses on evaluating and improving synchronization outcomes. Using real-world herd data, participants will learn how to identify protocol issues, interpret pregnancy results, and monitor technician performance, semen handling, and animal condition to improve reproductive success.
