21st Century Breeding: USA Mare Pregnant by 2014 Belgium National Champion

Silver Meadows Salsa expects foal by Matteo van 't Rietenhof

Imported frozen semen by Matteo van ‘t Rietenhof successfully inseminated in Brabant mare, Silver Meadows Salsa, proves successful.

At the turn of this century, attempts were made in America to inseminate a number of Brabant draft horse mares utilizing imported frozen semen from Europe. It is Trekpaard.net’s understanding that those efforts resulted in three pregnancies. Since that time, it is believed no additional frozen semen inseminations within the Brabant draft horse community have been made with many American-based breeders siting low pregnancy success rates and cost inhibitive import fees and veterinarian costs. Over the last eighteen years however, technological strides in equine fertility and insemination have improved equine frozen semen success. In view of the advances, South Carolina resident Stacy Pearsall imported frozen semen from Eddy Van Langenhove’s stud, Matteo van ‘t Rietenhof in the Fall of last year.

Equine Reproduction Centers

In September 2017, Pearsall worked with ERC De Morette to import ten doses collected from Matteo. After filing the necessary permit applications through the USDA, the dry-ship canister was transported via Agricon-Logistics from Belgium to New York City customs where an agent from Mersant vouched for the items and forwarded them onto Southern Equine Service in Aiken, South Carolina, where Matteo’s straws are presently kept. Southern Equine Service was chosen in large part because of their high insemination success rates. Furthermore, they’re conveniently located just 1.5 hours from Pearsall’s home.

Silver Meadows Salsa

The mare Silver Meadows Salsa (approximately 15-20 years old) is owned by Dr. Hernando Plata (Vet, MS, Dipl. ACT) and was found pregnant after the first insemination! Dr. Plato did the insemination himself, he caught it right when the mare ovulated. If all continues to go well, Matteo’s first American born foal will be on the ground in July 2019.

Motility check

Before the veterinarian performed the insemination, Matteo’s semen was examined and determined to be at 65% motility. According to the USA national average, post-thaw motility averages 31%, with a range of 11% to 53% (half being 52%). Despite Matteo’s above average post-thaw motility, the insemination timing still had to be precise. No more than eight hours after ovulation in fact. Unlike fresh semen, which usually maintains its fertilizing capacity for up to 48 hours, frozen semen is just 12 to 20 hours. As soon as Salsa ovulated, she was inseminated using the deep horn insemination technique.

Frozen semen of Brabants

International laws mandate that frozen semen bound for import/export requires stringent collection techniques by trained veterinarian professionals as well as certified documentation. These factors limit the number of studs presently offered for frozen semen export.
Those known by the editors are Dorus van de Molenhoeve, Frits van 't Rietenhof and Matteo van 't Rietenhof (inquire the stud farms about the possibility of international export).

Registering Brabants in the USA

After several breeders had trouble registering their (partly) Brabants in the US, the American Brabant Association has now confirmed to have created a registry. The ABA has great hopes that this registry will benefit the newly named American Brabant horse by keeping a database of imported European Brabant horses, Western Hemisphere-born Brabant horses, and Brabant horses crossed with Other Approved Draft Stock.
