Not getting desirable results from your artificial insemination program? Understanding a cow's reproductive physiology will help. If you're frustrated with results from your artificial insemination (AI) program, don't give up. Improvements can oftentake place easily, especially if you bolster your basic understanding of three things, says W.E. Beal of Virginia Tech University and Mel DeJarnette of Select Sires. Knowledge of these three things - the cow's reproductive tract and how it works, the estrous cycle and what it means, and embryonic/fetal development after fertilization occurs - should result in more AI-sired calves on the ground next year and vast improvements in the genetic quality of your cowherd.
