Pyrexia, or fever, is associated with a number of underlying diseases and can result in significant negative outcomes, including dehydration, laminitis, muscle wasting, weight loss, and in some cases death. Among performance horses, fever can also lead to loss of training and competition days. There are more than eight million horses in the United States, and over one million are seen by a veterinarian for fever annually.

“As more time passed, with no response to the antibiotics, Royal’s survival rate was diminishing,” Ammeson said. “How long can a horse live on three legs before he founders, or his body gives out?”

It was not always this way for Marguerite as her initial career started out as an administrative/executive assistant for a pharmaceutical company. She was drawn to horses as a child and rode whenever she could. As a teen, the opportunity for exposure to the racing industry presented itself when her family purchased a cottage in Kincardine, which backed onto the local fairgrounds where Standardbreds trained.

The UC Davis School of Veterinary Medicine, in collaboration with LONGMILE Veterinary Imaging, has completed the first phase of the validation of the MILE-PET, the first positron emission tomography (PET) scanner specifically designed to image the limbs of standing horses, using light sedation, eliminating the need for anesthesia.

Equine metabolic syndrome (EMS) is linked to obesity, insulin resistance, and laminitis—a painful and debilitating inflammation of tissue in a horse’s hooves, which can necessitate euthanasia in severe cases. This study aimed to equip horse owners and veterinarians with a potential path toward getting ahead of this debilitating disease through genetic screening. 

“In a time when so many veterans are so hesitant to take another prescription or fear getting addicted to opioids, equine assisted therapy gets veterans outside and allows them the amazing opportunity to work with horses to process their experiences,” said Congressman Barr. “As the Chairman of the Congressional Horse Caucus and someone who cares very deeply for our veterans, I believe increasing grant funding opportunities for evidence-based equine-assisted therapy and innovative therapies will greatly diversify the treatment options available to our veterans.”
