Artificial Insemination The Four Sixes uses artificial insemination (AI) on a routine basis for breeding purposes. Great care is taken to properly and safely manage stallions and mares during this process.

Phil Fox keeps a close eye on the 6666 Ranch Mare Management program.

Mare Management In addition to managing mares at the ranch being bred to stallions here, we handle shipped cooled or frozen semen sent in from outside stallions, as well. In addition, mares can be brought in for breeding, and do not need to be a long-term resident. Phil Fox (pictured here) is the horse division mare manager.
