As a breeder & stallion owner I find the service that Stallion AI offer invaluable to my business. Tullis’ team of experienced staff are, approachable, courteous & very knowledgeable when it comes to providing a complete end to end fresh/chilled semen delivery service.
Without exception they are extremely reliable, flexible & professional on how they deliver their services.
— Rebecca Fallows-Battersby, LG Sporthorses

Being a small stud (Sugar House Stud) with a homebred stallion, the advice and service I and my mare owners have received from Tullis, Kate and the team at Stallion AI has been invaluable. The standard of care is second to none and they happily go the extra mile to help market and showcase your stallion. The team at Stallion AI are friendly and approachable but also offer a wealth of knowledge and information. I couldn’t be more happy with the outstanding service that myself and my stallion, Franklyn Sugar have received, we are looking forward to another successful season in 2012 🙂 — Ruth Mealey (Franklyn Sugar)

Flayne Don Daiquiri, a fully graded British Warm Blood Stallion began his “career” at Twemlows. He couldn’t have had a better start, the treatment he received was 5 star, the care was wonderful, and the lengths to which the stallions are assessed and evaluated is extremely impressive. I would have no hesitation in recommending them for anyone intending to have their stallion collected, or mare inseminated. A family run business that cares as much for the horses as the owners!They take obvious pride in their work…and rightly too. — Richard Stiles (Flayne Don Daiquiri)

Gene Movers Pty Ltd have been working with Stallion AI Services / Cryogenetics since 2005. We have found Tullis, Kate and the team to be true professionals and dedicated not only to their clients needs but also to the strong business relationship that we have built over the years. The team go above and beyond to ensure that their exports arrive in Australia on time. I wholeheartedly recommend their service to anyone planning to ship to Australia. — Craig Mayne – Gene Movers Pty Ltd – Australia – Equine Semen Import Agents

I have always been able to have great confidence in the professionalism of Tullis and all at Stallion AI both when Marcus Aurelius has stayed at Twemlows for extended periods and in their dealings with my customers and with me. — Rowena Bertram – Marcus Aurelius

I have sent several of my stallions to Stallion AI Services to have their semen frozen and I would like to say what a terrific hassle free experience it was. I would thoroughly recommend Tullis and the team to anyone who wishes to send their stallions away for semen freezing. The care and attention is second to none and I could even watch my precious boys on the web cam whilst at home 100 miles away – perfect. The technical support you get from Tullis is invaluable and I do apologise to him for ringing during the stud season just to pick his brains. – once again thanks so much. — Trudy Goulding

I have used Stallion AI for a few seasons now. My Quarter Horse Stallion, Toys Triple Chick (Rooster) loves his stays and he is looked after like royalty (which of course he knows he is!) I have found true professionalism in all who work there and everyone is just so friendly. I wouldn’t even consider sending my precious boy to anyone else. Also I can drop in at any time on the CCTV to see him, bless! I feel sending any stallion there give hiin a credibility which going to an elite establishment involves. — Christine Richards (Toys Triple Chick)

I have used Stallions Ai for many years and cant recommend them enough. They are in my opinion the best AI centre in the country.
Always professional and friendly. I don’t think twice when it is time to send one of the boys in for a “holiday”. I know that when I go to collect them they will be fit, happy and looking a million dollars. Being able to see them on the CCTV is an added bonus.
— Nicola Nash

I recently discovered Stallion AI at their open day. Since then I have sent my welsh part-pred stallions Lynwood Cane and Lynwood Braint for collections.
The service has been brilliant; Extremely efficient and professional yet very caring and friendly.
Thank you to Tullis, Kate and your wonderful team.
— Lesley Pugh – Lynwood Stud

I use Stallion AI Services to store all the semen for Elite Stallions, I have been delighted with the service they offer both to myself and to all my customers.
In addition, their collection facilities are second to none, and as good if not better than many of the stations I visit in Europe. Tullis has a first class reputation amongst stallion owners in Europe, so cant recommend him highly enough!
— Lisa Niemy (Elite Stallions)

I would happily recommend Stallion AI Services, my boy came home looking a million dollars and everyone was so helpful and friendly throughout the whole process, we will certainly be sending our other boys there. — Charlie Swanston – Manager Monks Stud

I would like to say a huge thank you to Tullis, Kate, EJ and the rest of the team at Stallion AI services. Having bought a couple of stallions over the last two years it was never really my intention to send them away to stud as they are my competition horses and my babies. It was only when I visited Stallion AI and was introduced to the team there I realised they were very organised, efficient and caring in the way they looked after each and every stallion at the yard I decided this was the only place I would consider sending them to stud. Having never had anything at all to do with stallions or breeding before, Kate and Tullis couldn’t have been more helpful, clearly explaining exactly as and what I needed to do from that day up till the point they arrived at stud.

The open day at Stallion AI services attracted a lot of visitors and was very popular with mare owners looking at using my three stallions and for me that was the hardest part leaving them for a four week period. I couldn’t have been happier before I had even arrived home I received an email on each of their progress and access to see all three on my iPhone from the CCTV in each stable.

For the whole time they were at stud I received regular updates from Kate and the team, most importantly for me (being competition stallions and having a big show three weeks after their return home) is not one of them lost condition or weight, in fact Cadans who I was concerned about losing weight as in the past has been tricky to keep the weight on actually gained a little bit and looks fantastic for it.

Even the day we went to pick up the boys, we were met by the fabulous team at Stallion AI with all their rugs washed and put away in fantastic bags ready for them heading home. Nothing at all is too much to ask for the team there, each and every stallion is given the individual care you would give your own horse, not one of my boys lost condition or weight even their temperaments are the same as when we left them. Regular emails, calls and texts from the team keeps your mind at rest not to mention the CCTV on your iPhone meaning you can watch what your stallions are doing whilst in the stable. I can happily and will recommend Stallion AI services to anyone who was thinking of standing their stallions either just for a short period or a longer stay you most certainly will not be disappointed and you can leave knowing your stallion is in the very best care available anywhere in the UK. Many thanks to all at Stallion AI and look forward to standing my boys in 2015″. — Lara Dyson – Cyden Dressage

I’m so happy to have Sirdar back home safe and sound, I’m sure he thoroughly enjoyed his 2 week pleasure vacation at Stallion AI. All the staff were amazing, and Sirdar looks fantastic! A huge thank you to everyone: D — Samantha Gitzen – Blacklord Sirdar

Just to say a sincere thank you for going the extra mile on Tuesday to ensure Mill Law semen arrived in Scotland during the Queens jubilee holiday – Fantastic service!! Fingers crossed for the end result. Kindest Regards Lesley & Brodie — Leslie & Brodie

Just wanted to say a huge thankyou for the excellent service you have provided to me on the import of both Umenno and Kambarbay frozen doses. It has been a very quick, efficient and painless process! You have kept me informed the whole way through the process and I must say that I was quite surprised (and impressed) at how quickly the import was executed! Wouldn’t hesitate to recommend Stallion AI Services to anyone else wanting to do an import from the UK. I will certainly use your services should we do another import from the UK. — Janeth Flowers – Australia

Mersant International Ltd have had the pleasure of working with Stallion AI on both the import and export side of things, and we always find them their staff to be very knowledgeable and efficient.

My stallion Puzzles Pick & Mix thoroughly enjoyed his visit to Twemlows!!!! So did I when I did the AI Tech course, So very professional from start to finish. I would thoroughly recommend the Centre and the course. Good luck in 2011. — Jane Moore (Puzzles Pick & Mix)

My stallion Wolkenderry is a ‘walk in’ boy at Stallion AI Services. I can’t recommend Tullis, and the team highly enough!! Nothing is too much trouble, the stallions all look fab, and they manage to get the most difficult mares in foal!!! Good Luck to all in 2011. — Jackie Mathieson (Wolkenderry)

Stallion AI Centre is without a doubt the best AI center in the UK with international recognition and contacts, always pleased to discuss and plan ahead. PALOUSA SAN SEBASTIAN (black leopard spotted graded stallion by SAN REMO X GRIBALDI) has frozen semen stored with Stallion AI for the UK and EU, but will go back again for collection for Australia/NZ and USA. — Elsa Strandberg (Palousa San Sebastian)

Stallion AI Services provide a professional and commited customer service. Their products are reliable and reasonably priced. We were pleased with the way our stallions DESMOND and Trevoulter Storm were cared for whilst at Stallion AI Services. Trevoulter Barton Stud would not hesitate to recommend Stallion AI Services. — Kerensa Pluess-Cobbledick

Thanks again for all your help getting this frozen semen on its way to Australia! You have been great to deal with and made the whole process very straight forward and stress free! Next time I get this crazy idea in my head to breed horses I won’t hesitate in using you guys to source semen. Fingers crossed it all arrives here safely and over the next couple of years we get some awesome Habanero babies. — Travis Boehm (Australia)

The team at the stud is very nice and helpful in all aspects.
Del Boy is there at the moment in quarantine waiting for collection to go to South Africa.
The teams are so experienced I hope there is call for him to go again.
— Michelle Cuerden – Del Boy II

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.
— Dilly Bricknell and Call Again Casanova – Salentino Sports Horses

This is the second year that I have brought a group of Breeding and Genetics students from South Staffordshire College to Twemlows for a visit. Once again the students had a very educational and fun morning and have already asked if they can visit again! Thank you so much for your time and effort 🙂 — Linda De Matteo

Tullis and his team make the decision of sending my stallion Mill Law back to stud each year easy. Their passion for the job is second to none and the care my boy and all the others in the yard get is truly outstanding. He always looks amazing and I can sleep at night knowing he is in the best possible hands. — Nicola Baguley (Mill Law)

Twemlows AI services are very professional and i really enjoyed the AI tech course there. My stallion Oso Dashing Walter Brown will be going there this year to be collected from. — Amy Bannister (Oso Dashing Walter Brown)

Uptons Deli Circus has been standing as a ‘walk in’ stallion for several years. Tullis and the team provide an outstanding service every time. They are a pleasure to work with and their individual care for each stallion is second to none. Thank you all at Stallion AI Services. Circus will continue to stand there in 2011. — Rachael Thompson (Uptons Deli Circus)

We were absolutely thrilled today when the vet scanned all 3 of the mares you had, in foal to Olimpo. I can’t thank you and your team at Twemlows enough. Well done under difficult conditions. — The Hon Mrs. C. Wynn
