SBS Article - Katie Williams Photo for June 2016 Breeding season is a crazy time of year for us but we all relish in the long, hard days and generally unpredictable schedule because there are so many pay-offs. Not least among these pay-offs is the arrival of long anticipated foals and the opportunity to help our clients with their new breeding plans as there is so much excitement in the planning and realization of breeding goals. We at Select Breeders Services (SBS) are all horse crazy and love the opportunity to share in this with our clients. So far, 2016 has been a great year for us. Continued growth in our mare management services division has meant an increase in staffing, so we have several new team members to introduce.

The majority of equine embryos are collected from the donor mare and transferred immediately as fresh embryos or shipped cooled to a recipient station for transfer within 24 hr.

Featured Question

Does post-thaw motility correlate to fertility?

Fertility is inherent to each stallion as an individual and motility is just one attribute of sperm function. Fertilization is a complex process that requires numerous functional attributes of both sperm and egg. Therefore the true fertility of any semen - fresh, cooled or frozen - can only be determined by properly timed insemination of reproductively healthy mares. Nonetheless, sperm motility is still one of the best indicators we have for predicting success in a breeding program. If the post-thaw motility is quite low (10-20%) then fertility more than likely would be low. However, fertility does not necessarily improve with increasing motility; a stallion with a post-thaw progressive motility of 35% may be equally as fertile as one with 55% progressive sperm.
