Sherry Cervi has devoted her life to being a professional cowgirl, achieving results and accolades that have yet to be surpassed by any other horsewoman. Having won four Women’s Professional Rodeo Association World Titles in barrel racing, as well as multiple national titles (1995,1999, 2010, 2013), Sherry is this country’s leading female money earner. With her WPRA career earnings exceeding $3M in prize money, she has broken the glass ceiling for women in professional equestrian sports!

MediVet Equine began to work with Sherry and her string of horses in 2018, the same year she was inducted into the National Cowgirl Hall of Fame. Michael Kegley was attending an Equibrand conference, met Sherry and educated her on the benefits of MediVet ACS (Autologous Conditioned Serum). Sherry’s interest was piqued as she learned of the multiple benefits of ACS for her hardworking barrel horses.

It is no secret,horses that compete are serious athletes. Barrel horses run hard, turn on a dime and use every ounce of their muscles, joints and hooves to perform at this level. Sherry chose to try MediVet Equine ACS on three of her horses, each at different stages of their competitive careers. She has been thrilled with each horse’s unique physical improvements after being introduced to MediVet Equine’s scientifically based therapeutics.

Also important to note that Sherry’s horse of a lifetime, a mare named MP Meter My Hay, (aka Stingray), earned Sherry the 2010 and 2013 WPRA world titles. Stingray was responsible for putting Sherry firmly on the map and also contributed greatly to her top prize money winnings. Stingray has since retired from barrel racing, but has had an incredible second career as a top producing broodmare (through embryo transfer) and an occasional roping horse for husband Cory Petska.

Since her retirement, Sherry has been steadily producing and competing MP Jet Royal Money (aka Bernice), a full sister to the infamous Stingray. As with any horse discipline, building a solid string of horses takes time, training and a commitment to the horses health and soundness. During the course of Bernice’s career, the one challenge that they’ve faced was resolving an 8-month layup due to a hoof injury. Utilizing MediVet ACS in their recovery protocol, along with the mastery of Joao Neto, Equine Hoof Solutions, LLC – this talented mare has returned to barrel racing with gusto! Here’s hoping she stays on course and follows in the hoof steps of her famous sister.

At 14, Dash Ta Diamonds (aka Arson), owned by Trip duPerier, has also been a remarkable performer for Sherry and the duPerier’s family. Arson has led a productive career, winning the 4-year-old futurity, taking three riders to National Finals Rodeo (including duPerier’s daughter Callie) and winning the 2015 World Championships. With that much mileage, Sherry stated that Arson developed mild arthritis, but with the help of MediVet ACS, continues to lead an active career.

Not to be out-done by his wife, Cory Petska also competes on the western rodeo circuit and is a world champion team roper (heeler). As with barrel horses, roping horses also need to execute quick turns and sliding stops, which can lead to sore hocks and feet. Cory has seen great maintenance results with the MediVet ACS treatment of his horse Chumley.

Together Sherry and Cory are constantly on the road traveling to competitions. From their summer home base in Wisconsin, or their winter base in Arizona – they haul the horses to Texas, Nevada, California, Washington, and Iowa for competitions. These horses are true road warriors, and all that hauling can really take a toll on the horse’s stress response and immune system.

This is where Sherry has seen a significant improvement in her horse’s overall health. In a recent conversation with Sherry she stated, “This product (MediVet ACS) is better than anything else out there. We go to a couple rodeos a week, and it helps protect against wear and tear and the stress of all the hauling!”

MediVet Equine is humbled that we could have an impact on the health of Sherry’s horses, and we admire her career successes and exemplary horsemanship. We admire that she gives back to the western community by fostering development of the next generation of riders. Through her non-profit organization, Sherry Cervi Youth Championships, she holds annual youth barrel races in California, Arizona, and Minnesota. At these events, she interacts with all the kids and encourages their growth in the sport by raising funds for an annual scholarship program.
