Evaluation of Cooled-storage After Thawing Frozen Stallion Semen

Semen collected from stallions can be extended and used for fresh insemination, extended and stored at 5 to 8 ° C for 24 to 48 hours prior to insemination, or cryopreserved and stored indefinitely in liquid nitrogen. Breeding mares with cryopreserved semen requires specialized equipment for storage and thawing of semen and more intensive mare management. However, not all equine breeding programs are equipp ed to utilize frozen semen. Consequently, the initial objective of this study was to evaluate the longevity and fertility of frozen stallion semen once it had been thawed, extended and maintained at 5° C for 48 hours in a passive cooling container.
