BREEDING VIA ARTIFICIAL INSEMINATION:
The first step, once you have decided to breed your mare, is to select a stallion and contact the stallion owners. You should find out which days the stallion is collected, how the semen is shipped and time frame for shipping. In addition, for international shipping, you must find out if the breeders are familiar with procedures for shipping semen across the border. Since the outbreak of Contagious Equine Metritis in Kentucky a few years ago, there are strict rules for getting semen shipped into Canada.
Next, your veterinarian needs to perform an initial assessment, including ultrasound examination, and other diagnostics depending on the mare's reproductive history. The initial ultrasound exam can provide information on when the mare is predicted to be in heat, and her potential timing of ovulation. Once the mare is in heat, she needs to be followed closely to predict the time of ovulation. For fresh chilled semen, the semen needs to be inseminated prior to the mare ovulating, and will generally remain viable within the uterus for up to 48 hours. For frozen semen, the mare needs to be inseminated within 4-6 hours after ovulation, and requires much more diligent monitoring of the mare through ultrasound. Once the mare is bred, medications are often administered to promote ovulation. Ovulation is confirmed after insemination, and the mare is checked 14-16 days after ovulation for pregnancy and to ensure that there are not twins present, as mares cannot carry twins to term.

FROZEN INSEMINATION:
Frozen insemination requires much more diligent and frequent monitoring of your mare to optimize the chances for success. In addition, special equipment and expertise is needed. As such, it is preferred that all mares to be bred with frozen semen be shipped into our Prescott farm location.
