Kentucky Equine Research developed EO-3™, a potent marine-derived oil that is rich in omega-3 fatty acids. EO•3 is a palatable oil that is top-dressed onto the feed. EO-3 contains the omega-3 fatty acids DHA and EPA. KER has shown EO-3 to be highly palatable when compared to other marine-derived oils. EO-3 is intended to be fed to horses of all classes and working levels to improve the critical omega-3:omega-6 ratio in their diets.
