Breeding Strategies
Our Thursday Reproductive Moment on DairyLine Radio features a conversation with Dr. Ray Nebel of Select Sires. The topic today focuses on the next step after an early pregnancy test.
Current statistics tell us that approximately 60-65% of the cows bred on first service will remain open. To increase the chances of settling on the second service, a couple of different strategies are recommended:
1. Give GnRH one week before the early pregnancy exam. Upon being found open at the exam, prostaglandin is then administered followed by the final GnRH injection 2 days later. Breeding is recommended 16 hours later, in other words, 3 days after they were found open on exam.
2. If declared open on the early pregnancy exam date, begin the Ovsynch program. GnRH injection followed by prostaglandin 7 days later, GnRH 2 days later and then breed 16 hours later. This results in breeding 10 days after they were found open on exam.
