Select Breeders Southwest


SBSWA growing interest in frozen semen within the horse industry and the success of SBS in Maryland, prompted Paul Loomis and Whit Byers to form Select Breeders Southwest, Inc. in 1992. Recognizing the need to provide on-site freezing services to stallion owners and veterinary clinics, SBSW introduced the industry’s first fully equipped mobile semen freezing laboratory in 1994. Initially working primarily with Warmblood Sport Horses and Arabians, SBSW was well established and poised for growth when the AQHA ad APHA accepted frozen semen in the year 2000. With the launch of the SBS Affiliate Laboratory program in 2000 it became unnecessary for the SBSW mobile lab to travel throughout the entire United States and as a result a new, smaller mobile lab was introduced in 2002 with a second to follow in 2004. Whit Byers retired in January 2010 and Paul Loomis took over full ownership of SBSW. Debbie McPherson is the General Manager and directs the day to day operations in Aubrey.

PaddocksSBSW is located on approximately 40 beautiful acres in Aubrey, Texas, “Horse Country USA.” Our facility includes a laboratory with the latest technology for semen analysis, a large frozen semen storage area, two barns, lush green pastures plus private turnouts for your stallions and mares. It is also home to our two mobile laboratories.

We are equipped to assist you with your stallion management needs whether they be training him for collection, breeding live cover, performing cooled semen analyses, processing cooled semen for shipment, freezing semen, standing your stallion for the breeding season, etc. Our facility is inspected by the USDA bi-annually and approved for the collection and processing of semen intended for export out of the United States.

Our caring staff will treat your mare as one of our own during her stay. She will not be just another number but will be treated as an individual and feel at home in one of our large pastures, her own private stall, or one of our foaling stalls. She will be well cared for whether she is getting ready to foal or being managed for breeding with fresh, cooled or frozen semen.

Tank roomOur frozen semen storage and distribution services are second to none. Our facility houses approximately 49,000 doses of frozen semen, for both domestic and export use, from hundreds of stallions. We are well versed in the art of exporting frozen semen and send approximately 60 shipments (~2500 doses) throughout the world each year. Due to our vast experience in exporting equine semen we are able to get shipments to their destinations in a timely manner and without unnecessary delays.

Utilizing our two mobile laboratories we are able to offer our semen services to farms and veterinary clinics. Each of our mobile labs has equipment for semen collection, processing, and analysis which includes a controlled rate cell freezer and a Hamilton-Thorne computer assisted semen analysis system. Our mobile labs are USDA approved. If your collection facility is approved by the USDA we are able to process semen for export to foreign countries. Although our main territory includes Texas, Oklahoma and Arkansas we would like to discuss traveling to your facility, wherever it may be. Please call our office or email
