Synchronization Success: Heifer Puberty and Timed AI
There were three main priorities beef cattle industry researchers had when developing fixed-time AI protocols that are now found in most university recommendations and allied industry breeding resources, said University of Missouri researcher David Patterson during a recent reproductive strategy webinar from the National Cattlemen’s Beef Association.
Here are the reasons:
1. Easy to schedule and administer
2. Reduce or minimize animal handling
3. Result in a highly synchronized, fertile estrus and ovulation
But now researchers are asking what’s next.
Patterson gives a detailed look at why we must understand the science behind fixed-time and split-time AI protocols for the overall health and performance of our future cow herds in the first part of an extensive webinar series.
