Ramiro B
Sire of Nations Cup Level Show Jumpers and 4* Eventers. One of the most popular eventing stallion in UK with over 100 mares in 2016 and he was also the first horse to have been made an ambassador with the BWP studbook due to his phenomenal breeding record.
Peppermill
Peppermill has always had an outstanding and relaxed temperament. He has outstanding versatility in attitude and temperament as well as his jumping. He would compete at world class level and between competitons came to visit the stud and be hacked out at weekends by his amateur owner.
Cassionato
Successful international Grade A show jumper, who together with his rider Michael Whitaker was part of the British team at the 2016 Rio Olympic Games as well as the 2015 European Championships and in the same year helped Britain win the CSIO 5* Furusiyya FEI Nations Cups at La Baule, Rotterdam and Rome.
Murka’s Gem
Murka’s Gem is the identical reincarnation of the original Gem Twist and clearly knows what it’s all about, both when jumping and breeding. He already has his first crop of foals on the ground and is an exciting prospect for anybody looking to breed a serious show jumper.

Client Comments
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
