De Niro – Wolkentanz – Forrest xx

An excellent pedigree, modern type, and talent for the sport of dressage mark this new stallion at Van Olst Horses as one to watch. At his Stallion Performance Test, George Clooney earned scores of 8 or higher in all categories and was described in his testing report as ‘an honest and reliable stallion….George Clooney moves with good elasticity, ease, and excellent balance.”

The potential for top sport is no surprise when evaluating George Clooney’s pedigree. He is sired by none other than DeNiro, the charismatic Donnerhall son who has been ranked first on the World Breeding Federation for Sport Horse Sire Rankings the past two years. De Niro, was Reserve Champion of his performance test with a score of 141.93 and had a wonderful sport career with over 24 wins at S-Level.

George Clooney’s dam is by Wolkentanz, the Weltmeyer son who was Champion of his Licensing, Reserve Champion of his Stallion Performance Test with 140 points in dressage, and winner of the Bundeschampionat. The combination of George Clooney’s dam bred to DeNiro has been extremely successful and includes the full-siblings Despino and Delmar that are successful at Grand Prix. Maternal granddam Fricka brings the influence of the Thoroughbred stallion Forrest and she is also the granddam of Isabel Werth’s Don Johnson.

The first George Clooney foals will arrive in Holland in the spring of 2015. He offers essential access to proven German sires and we anticipate that he will improve the use of the hind leg as well as rideability and temperament in breeding combinations.

Canadian Breeders Shipping from Moore Equine

To help our Canadian breeders save on shipping expenses and the hassle of getting an import permit, Hilltop Farm ships a limited amount of frozen semen to Moore Equine in Calgary, Alberta at the start of each breeding season for distribution within Canada. We will ship four doses of frozen semen to Moore Equine for each contract booked prior to this group shipment. Doses will be distributed at a max of two doses per cycle. If a mare is not confirmed in foal after utilizing those doses, it would be necessary for the mare owner to follow our typical import procedure to obtain semen for any additional breeding cycles. All shipment requests for semen in Canada will still be sent to Hilltop Farm and follow Hilltop’s standard notification schedule. For more information on deadlines to be included in the group shipment to Canada or to inquire about frozen semen already located in Canada contact Brittany.

Mare Management Reminders

At Hilltop Farm we want to work closely with you and your veterinarian to ensure a successful breeding season and are available for questions at any time. The following information includes some basic suggestions as well as reminders on a few requirements for your breeding contract.

A Breeding Soundness Exam including a uterine culture is recommended, but not required, for all mares prior to breeding. If a mare fails to settle after two breeding cycles, Hilltop Farm will require a culture and cytology to be done at that time prior to any additional shipments of semen. We always recommend your vet checking your mare post-breeding to confirm ovulation. If a mare hangs on to a follicle longer than expected, it can be less expensive to ship additional semen than it would be to breed a second complete cycle. Getting your mare settled in foal is just the beginning. We recommend multiple pregnancy checks to help prevent cases of twins, misdiagnosed pregnancies, or lost time in the breeding season. The following schedule is what we recommend; only the first and fourth checks however are required by your breeding contract.
  • 1st check (Required): 14-16 days post ovulation - optimum time for vet to pinch off a twin if more than a single ovulation is noted.
  • 2nd check (Recommended): 28 days post ovulation – to confirm a viable pregnancy as the heartbeat normally appears by day 25.
  • 3rd check (Recommended): 35-40 days post ovulation – to confirm maintained pregnancy prior to endometrial cup formation. Mares that slip foals early may not come back into heat.
  • 4th check (Required): 55-60 days post ovulation – final confirmation of pregnancy in its critical first trimester.
Following your mare’s 55-60 day pregnancy check, please have your vet finish completing the Mare Breeding Passport and return it to Hilltop Farm by September 15th. This Passport is used in all stallion reports to various breed registries and is used to generate a Breeding Certificate so that you can register your foal.

Registration Information

Your mare’s registration and approval play just as important of a role as the stallion’s approvals when determining registration options for your foal. Please keep in mind that in order to register your foal with a specific association, your mare may first need to be presented to that registry for approval. In addition to the registries a stallion is approved with, there may be additional registration options based on your mare’s eligibility and the stallion’s credentials. If you are confused at all on registration options for a potential foal, please speak with Hilltop Farm and your breed registry PRIOR to booking your breeding.
