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.
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.
Embryo Transfer The Four Sixes maintains its own recipient herd. Embryo transfers are done on site, and we also handle embryos shipped in for implantation.
Foaling Mares are foaled out in a controlled setting under live observation 24 hours a day, seven days a week. Every foaling is attended by a licensed veterinarian and foaling attendants.
