A blend of direct fed microbials is important to support healthy digestive processes. Crucial to an animal’s gut are the “friendly bacteria” for microbial balance. Prebiotics (Fructooligosaccharides FOS) are added to this probiotic blend help increase the nutrients needed for specific bacteria to survive. Digestive enzymes are used to help break down food for proper digestion and absorption. Wonderful to use before and after worming or antibiotic protocols. The bacteria components of Pre Probiotics are freeze dried and stabilized with moisture scavenging silicates so they do not need to be refrigerated. An average size horse uses 10 grams per day.
