Dr. Cliff Lamb: Future of Beef Reproduction | Ep. 11

A successful breeding program depends on understanding the onset of pregnancy in beef herds. Monitoring heat cycles, observing the right timing for insemination, and identifying/addressing fertility problems are all parts of this process. Artificial Insemination (AI), for example, can increase pregnancy rates and improve genetic progress in beef herds. Indeed, the beef industry has been using reproductive technologies at an increasing rate, such as in vitro fertilization and genomic selection. In this episode, Dr. Cliff Lamb discusses how these technologies can improve breeding programs, make them more efficient and accurate, and thus, improve genetics and herd performance.

“We utilize embryo transfer and in vitro fertilization. Those technologies are continuously evolving and may have a bigger role in the future, rather than just the utilization in synchronization for AI." - Dr. Cliff Lamb
