Aside from basic herd wellness and care, we offer extensive equine reproductive services, including artificial insemination and reproductive ultrasounds.

Equine Reproductive Ultrasound

The use of reproductive ultrasound for breeding evaluation, as well as insemination timing, can increase the likelihood of pregnancy in your brood mares. Pregnancy diagnosis can be performed at or around 15 days post-insemination, giving sufficient time to reorder semen if needed.

The technology of reproductive ultrasound is safe and relatively low in cost, making it a necessary tool for the equine breeder. Green Prairie San Jose offers skill and experience in the use of reproductive ultrasound.

Green Prairie San Jose produces a regular Equine Newsletter for all of our horse lovers. View a copy of the newsletter and more in the News & Resources section of our website (Coming soon). Contact us for any questions you may have or to schedule your appointment.

Equine Artificial Insemination

We provide equine artificial insemination services with cooled semen. Breeding mares with cooled semen requires that all parties involved—mare owners, stallion managers, and veterinarians—need to coordinate semen shipments with the mare’s ovulation before shipping semen. Some potential items to consider:

  • Cost of stallion collection
  • Cost of preparing semen for shipment, number of collections provided per breeding, the cost of shipping by air, and how shipping containers must be returned
  • Days of the week stallion is collected Times when stallion is unavailable
  • Days’ notice stallion manager needs before semen shipment
  • Latest time one can call to obtain semen Longevity of semen
  • First cycle conception rate of the stallion Method of transport used
  • Number of times mare can be bred if she does not conceive, according to the contract

First cycle conception rates tend to be slightly lower with shipped semen than with natural breeding. Cooled semen opens up increased opportunities for available stallions, decreases some risks, and eliminates transport of the mare to the stallion’s breeding facility. Artificial insemination does require more intense breeding management, and veterinary costs are higher. Mares need to be examined regularly and bred within 24 hours of ovulation. Using HCG can influence ovulation, although response can be variable between mares.
