The April 28 Dairy Cattle Reproduction Council (DCRC) webinar features ovulation synchronization (Ovsynch) programs, the basis for most timed artificial insemination (A.I.) programs in dairy cows in the U.S. Richard Pursley, Michigan State University (MSU) professor of animal science, will provide an update on these valuable pregnancy rate enhancement tools. The webinar starts at 1 p.m. Central time.

Dairy cattle reproduction physiology researchers work to understand the mechanisms underlying substandard pregnancy rates. Applied reproductive research programs strive to control ovarian physiology to optimize fertility of lactating dairy cows. Through their studies, researchers develop and use information to improve the fertility potential of Ovsynch.

With this strategy in mind, reproductive physiologists have developed programs that increase the odds of pregnancy from approximately 30 percent, following standing estrus, to approximately 45 percent. These programs – G6G, Double Ovsynch and Presynch-10 or 11 – are known as “fertility programs.” These fertility enhancements provide additional benefits, including delaying time to first service, cutting pregnancy losses and reducing twinning.

The 2017 webinar series provides information-packed forums every other month. These highly regarded sessions offer attendees from across the U.S. and around the world access to high-quality information and interaction with industry experts from the comfort of their farm or office.

The webinars feature highly rated topics from previous DCRC annual meetings, as well as other areas of importance. For the first time, DCRC will offer a webinar in Portuguese, which is slated for Oct. 27.


Like last year, DCRC will offer a webinar in Spanish on Dec. 15. Each webinar begins at 1 p.m. Central time.
