Determining a horse’s body weight is important for bodyweight and feeding management, and administration of medication. The Healthy Horse App allows horse owners and professionals to estimate the body weight of adult Arabians, draft horses, adult and juvenile miniature horses, stock horses, saddle-type horses, ponies, Warmbloods, and Thoroughbreds using new equations developed through University research by entering in the equine’s height, body length, neck and girth circumference. Ideal body weight is also calculated for each breed-type using newly developed equations through University research by entering in the equine's height and body length. The app gives an estimate of an equine’s actual and ideal bodyweights and should not replace an examination by a qualified professional. The Healthy Horse App is now available in both Spanish and English and users can enter measurements in either imperial or metric units with results displayed in either pounds or kilograms.
