We provide a comprehensive veterinary service for horse breeders

Artificial Insemination

We strive to provide a comprehensive veterinary service for horse breeders and are able to offer a complete stud medicine service to help you from the time you start thinking about breeding until after your foal is born. We have vets with particular skills, expertise and experience in all areas of equine reproduction including:

• Fertility and infertility examinations

• Artificial insemination including semen storage and handling

• Pregnancy diagnosis

• Management of the brood mare

• Foalings, including difficult deliveries and caesarean sections

Before breeding from your mare, a full reproductive examination should be performed which will allow the veterinary surgeon to assess her suitability for breeding and highlight any potential reproductive problems.

We have had excellent results in our AI services with fresh, chilled and frozen semen. These services can be provided both out on your yard or at the Equine Hospital in Lanark. Our veterinary surgeons will be happy to discuss the advantages and disadvantages of using freshly collected semen, fresh chilled semen or frozen semen. Successful AI depends on regular monitoring of the mare’s ovaries and uterus so that she may be inseminated as close to ovulation as possible. The timing of insemination will be determined by which semen is chosen. For fresh or chilled semen, conception rates are highest when insemination is performed within 24 hours preceding ovulation. Frozen-thawed semen has a relatively short life span and therefore requires that mares be inseminated immediately before (within 6 hours) or after (within 4 hours) ovulation. Therefore management of mares for insemination with frozen-thawed semen is more intensive and mares require multiple ultrasound examinations to assess the correct time for insemination. Conception rates for mares using frozen-thawed semen are often lower and therefore ideally this should be reserved for mares with the best reproductive histories. Insemination with chilled semen requires good communication with the stallion stud so that semen is delivered on time.

After insemination, your mare will be checked for ovulation and for post-breeding inflammation. Provided all is well, your mare will be scanned at 16 days following ovulation and if pregnant, it is advised that scans be performed at 28 and 45 days to make sure the pregnancy is developing normally. Older or problematic mares may require further treatment in this early period.

If you are interested in breeding from your mare, please contact our reception team on 01555 660000 to arrange a call with one of our reproduction vets to discuss your individual requirements.
