This supplement helps stimulate appetite and maintain digestive health in Horses. Ultra Cruz equine appetite booster is beneficial to use during weaning and in the diet of Horses with a poor appetite. Provided as a palatable, easy-to-feed Pellet. A healthy Horse is host to billions of bacteria of varying types and these bacteria are crucial to keep the horse's gut functioning normally. If these bacteria are unbalanced, the Horse may not digest nutrients properly. Prebiotics are sources of non-digestible, soluble fiber that serve as food for beneficial bacteria in the intestine. Prebiotics, unlike probiotics, do not contain live bacteria and work by providing food for existing bacteria, which supports their growth. Examples of prebiotics are: arabinogalactan, fructooligosaccharides (FOS), inulin, manna oligosaccharides (mos. ), pectin and psyllium.
