Over the past 30 years the Grayson-Jockey Club Research Foundation has funneled nearly $20 million into studies aimed at improving horse health. This year the effort continues with funding for a dozen new projects in fields ranging from laminitis to lameness diagnosis. A sampling:

-Detecting lameness at the gallop: Kevin Keegan, DVM, of the University of Missouri, is developing an objective method (using a calibrated instrument) for detecting obscure, subtle lameness in horses at the gallop. The goal is a low-cost method that can be used in the field to increase understanding of lameness in racehorses. 

-Deworming and vaccines: While it’s not unusual to deworm and vaccinate horses on the same day, recent findings have raised concerns about possible interactions. Martin Nielsen, DVM, of the University of Kentucky and Gluck Equine Research Center, is investigating whether deworming causes an inflammatory reaction that affects vaccination. 

-Imaging injured tendons: Horses recovering from tendon injuries are often put back to work too soon and suffer re-injury. Sabrina Brounts, DVM, of the University of Wisconsin–Madison, is exploring a new method developed at the university to monitor healing in the superficial digital flexor tendon. The technique, called acoustoelastography, relates ultrasound wave patterns to tissue stiffness: Healthy tendon tissue is stiffer than damaged tissue. 

-Detecting laminitis early: Hannah Galantino-Homer, VMD, of the University of Pennsylvania, is investigating possible serum biomarkers (molecular changes in blood) that appear in the earliest stages of laminitis. The goal is to develop tests for these disease markers so that treatment can start when laminitis is just developing, before it’s fullblown and damages the foot. 

Other new studies include evaluations of a rapid test for salmonella; investigation of how neurologic and non-neurologic equine herpesvirus 1 (EHV-1) spreads cell-to-cell in the body; an effort to map the distribution of stem cells after direct injection into veins; and more.
