Hindgut Supplements for Horses
View a list of the best hindgut supplements for horses in Mad Barn’s equine feed database. Hindgut supplements are digestive support products formulated to promote a healthy large intestine and cecum, where fiber fermentation takes place, helping to maintain microbial balance, a stable hindgut pH, and normal manure quality in horses prone to digestive upset.
Equine hindgut supplements may contain ingredients such as prebiotics, probiotics, yeast cultures, digestive enzymes, and buffers that support fermentation and help counter the effects of high-grain diets, sudden feed changes, or hindgut acidosis. These products vary widely in active ingredients, format, serving size, and added components such as vitamins, minerals, or fiber. Compare active ingredients, feeding directions, cost per serving, and nutritional profiles to find a supplement that fits your horse’s needs.
