Producer Perspective on Reproductive Technologies
Range Beef Cow Symposium
The Blairs first started using timed artificial insemination (TAI) in the early 2000s. After trial and error, they settled into using the 14-day CIDR® protocol for heifers because it tightens up the second cycle and results in a 70%-75% conception rate in 28 days. For heifers, he said, they use Kamar heat detection patches.
