ANSC 3080 Lecture Notes - Lecture 3: Artificial Insemination, Semen Collection, Semen Quality
Document Summary
Semen collection and freezing for commercial purposes and breeding soundness examination of sires for natural breeding. In this laboratory class, you will learn how breeding soundness examination (bse) of male domestic animals is performed and its importance for animal breeders, farmers, and artificial insemination companies. After completing this laboratory class, you should be able to: Become aware of the work performed by artificial insemination centres in the livestock industry. Understand the basic concepts of bse and its importance. Become familiar with the methodologies and equipment used for bse. Learn how to exam semen quality and concentration, and spermatozoon morphology. Semen collection and freezing for commercial purposes (semex video). Mock bse of sires used for natural breeding. Evaluation of frozen bovine semen and extended swine semen. The goal of bse is to identify males that are unfit for breeding and avoid fertility losses. In large studies performed worldwide 20-35% of beef bulls failed the exam for multiple reasons.
