Some of the country’s top American Quarter Horse sires are included in Colorado State University’s (CSU) 17th Annual Online Stallion Auction to benefit equine research.

The auction, currently underway and running through Jan. 16, is available at and sponsored by the CSU Equine Reproduction Laboratory and Orthopaedic Research Center.

Breedings with about 40 registered American Quarter Horse stallions are included in the service auction. Among them are top national winners in barrel racing, cow horse, cutting, ranch horse and reining competitions. Premium sires include One Time Pepto, a $10-million sire and 2014 NRCHA No. 1 Leading Sire All Ages; WR This Cats Smart, an NCHA All-Time Leading Sire with progeny winnings over $6 million; Olena Oak, a two-time AQHA World Champion Cowhorse and No. 1 NRCHA Leading Money Earner; and Slick By Design, a three-time NFR barrel-racing qualifier.

“This sale offers both tremendous quality and variety, with more emphasis on barrel-racing horses than in years past,” said Jerry Black, DVM, director of both the CSU Equine Reproduction Laboratory and the university’s Equine Science Undergraduate Program. "We’re offering something for everyone interested in breeding American Quarter Horse performance horses, whether for competition or ranch work."

Proceeds will support research conducted by scientists at the CSU Equine Reproduction Laboratory, which provides clinical services and works to improve equine reproductive health, and the CSU Orthopaedic Research
