Abstract

The objective of this study was to compare estrus synchronization and fixed-timed artificial insemination (FTAI) protocols in commercial beef heifers to be bred with sexed semen. Secondly, the trial evaluated the benefit of delaying insemination for 24 hours in heifers not demonstrating estrous activity following synchronization and prior to FTAI.
