Semen Freezing & Storage
We are affiliated with Select Breeders Services (SBS), and offer on site freezing and storage services at The Four Sixes to the general public. In addition, frozen semen is available in Australia, Argentina, Brazil, the European Union, Mexico, New Zealand, Paraguay and Uruguay.
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.
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.
The Four Sixes maintains its own recipient herd. Embryo transfers are done on site, and we also handle embryos shipped in for implantation.
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.
**This Foaling Calculator and Mare Care Vaccination Schedule is intended for use only as a foaling date estimation tool and recommended mare care timeline. It does not consider differences between individual mares and should not be interpreted as an exact foaling date, you should allow for a 10 -/+ day window based on 343 days gestation. Four Sixes Ranch is not responsible for problems, injury or inaccuracy arising from the use and/or misuse of this tool. The 6666 Ranch recommends that you work with your local veterinarian and follow any recommendations they have.
