Improvements in equine semen processing techniques that aid optimal fertility

Abstract

Technology is constantly changing in all aspects of our lives. Although developments in the equine breeding industry do not move as fast as those in computers or cell phone technology, there is nonetheless a slow and steady progress forward with respect to the diagnostic tools and equipment veterinarians have available, as well as improved protocols for semen processing and breeding management of the mare. Improved success with assisted reproductive technologies like embryo transfer and intracytoplasmic sperm injection (ICSI), have led to increased utilization by breeders in recent years, and frozen semen has allowed growth in the global genetics market. Some of the advances in semen processing techniques shall be reviewed here; however, whether these advances in technology have resulted in an overall improvement in fertility rate is tough to say. Aspects of semen processing are just a small piece of the puzzle when it comes to achieving a pregnancy in the mare; there are so many other variables that can impact the final result. Nonetheless, every little bit helps and only by optimizing all the pieces do we give ourselves the best opportunity for success. Therefore, it is in our best interest to utilize those semen processing techniques that are available in order to prepare a breeding dose that will provide the most optimal chances of conception.
