Jensen outlines the semen collection process using trained teaser steers and artificial vaginas, emphasizing the importance of evaluating motility, morphology, and concentration. He stresses that breeding soundness exams are critical “cheap insurance” to ensure bulls are structurally sound, reproductively normal, and capable of settling cows, especially given today’s high cattle prices and demand for herd growth. Melgar details laboratory evaluation, including microscopic assessment and computer-assisted semen analysis (CASA), along with verification of concentration using a nuclear counter. He explains dose differences between beef and dairy semen and the importance of progressive motility. Jensen then describes the industry’s adoption of sexed semen, the role of flow cytometry, and collaboration with major providers. Because of extensive quality control, bacterial testing, DNA verification, and packaging steps, turnaround time for sexed semen is typically about two weeks, compared to roughly a day for conventional semen. The discussion shifts to health, disease testing, and nutrition. For domestic use,…
