Minster Equine are a team of experienced vets offering reproductive services in North Yorkshire. We offer AI breeding packages for owners looking to breed from their mares. From first-time breeders to experienced professionals, we have the knowledge and facilities to achieve a successful pregnancy and foaling. We can assist you with managing your mares cycle for natural covering or artificial insemination, both fresh chilled and frozen.

Our purpose built veterinary clinic in Poppleton, York has all of the facilities you’d expect to find at a BEVA Approved AI centre. We also have provision for the storage of frozen semen and an in-house laboratory for processing and assessing semen quality and motility.

Reproductive work can be carried out at home or mares can visit the clinic as an outpatient. Owners may choose to leave their mares with us for a number of days to ensure that they are inseminated at the optimum time. We have the facilities to accommodate this with stabling and grazing on-site under 24-hour supervision by our veterinary team.
