Storage & Distribution Services Include
Frozen Semen Storage

SBS houses an extensive inventory of over 100,000 doses of equine frozen semen and embryos at our state-of-the-art facilities in Chesapeake City, MD, and Aubrey, Texas. Each storage container’s liquid nitrogen levels are carefully maintained using an on-site, 1,500-gallon bulk liquid nitrogen tank. With this advanced infrastructure, SBS provides breeders with confidence and convenience, ensuring their frozen semen and embryos are securely stored and readily accessible for future breeding endeavors.
Frozen Semen Distribution

Our distribution program is meticulously designed to be convenient and efficient for all parties involved. Once stallion owners secure a contract with a mare owner, they simply authorize SBS to release the frozen semen. When ready, the mare owner contacts us to request the shipment. Typically, requests made by 11am (CST) are shipped the same day via FedEx.
Quality Assurance Program

For over 30 years, Select Breeders Services (SBS) has set the standard in equine reproduction by offering high-quality, rigorously tested frozen semen. Our Quality Analysis Program ensures mare owners and veterinarians receive semen that meets strict quality requirements. The SBS quality analysis includes:
- Motility Analysis: Conducted by CASA at 10 and 30 minutes post-thaw.
- Sperm Concentration: Measured by Nucleocounter.
- Bacterial Culture: To assess the presence of mare pathogens or heavy bacterial growth.
To distribute frozen semen commercially, samples must meet these quality standards:
- Motility Requirement: Minimum 30% progressively motile cells, providing at least 240 million progressively motile sperm per sample.
- Bacterial Safety: Samples must be free from pathogenic bacteria, such as E. Coli, Klebsiella pneumonia, and Pseudomonas aeruginosa, as well as any heavy bacterial contamination.
Import of Frozen Semen

SBS provides comprehensive import services to simplify the process for our clients. We manage import permit applications and prepare all required documentation to minimize delays at U.S. Customs, ensuring a seamless experience when importing equine frozen semen. Trusted by breeders and veterinarians alike, SBS is recognized as the industry’s leading name in high-quality frozen semen. To uphold this standard, we require a post-thaw quality control analysis for all non-SBS frozen semen before commercial distribution under the SBS brand, guaranteeing accuracy, reliability, and peace of mind for our clients.
