ADR (formerly Dr. Bill's Foal Pac) is a unique digestive aid containing the most effective mannanoligosaccharides available to bind pathogenic bacteria in the intestine and boost immune response along with a specifically selected blend of direct fed microbials that work in a synergistic manner to provide the greatest boost to the horse's digestive system available. ADR has been proven to help with: *controlling foal scours *stimulating appetite in horses off feed or horses under stress *re-establishing normal digestive function post colic surgery *controlling diarrhea in older and adult horses *aiding recovery during colic *aiding in preventing colic.
