Client Comments

There was never any doubt in my mind where I would take Call Again Casanova for collections when I finally decided to let him take up his duty as a breeding stallion. Stallion AI should be the emergency number in any stallion owners contact list, the whole team do an absolutely superb job with every stallion, respecting each one as individuals who all require different handling. The yard is always meticulous and I’ve never seen so many happy horses all under one roof (or two as the case may be) they are always accommodating and willing to help under the shortest of notice periods. I can sleep comfortably at night when I’m away knowing Call Again Casanova is receiving the best personalised care the UK stud market has to offer.
Thank you all again.
