Determining a horse’s body weight is important for weight and feeding management, and administration of medication. The Healthy Horse App will allow horse owners and professionals to estimate the body weight of adult Arabians, stock horses, saddle horses, ponies and miniature horses using equations developed through University research by entering in the equine’s height, body length, neck and girth circumference. Ideal body weight and a body weight score (to assess the likelihood of being over-weight) will also be calculated for Arabians, ponies and stock horses from newly developed University of Minnesota research. This app gives an estimate of an equine’s body weight and should not replace examination by a qualified professional.
