Feed Additives for Horses

Explore feed additives used in horse feeds and supplements in the Mad Barn Equine Feed Database. This category includes non-nutritive and functional ingredients commonly found on equine product labels, such as binding agents, preservatives, anti-caking agents, flow agents, carriers, emulsifiers, stabilizers, processing aids, flavoring agents, antioxidants, pellet binders, and coating agents.

Review detailed ingredient profiles, functions, and common uses to understand how these additives support product stability, shelf life, texture, flowability, palatability, nutrient delivery, and manufacturing consistency. Compare additives by source, inclusion purpose, functional role, and use in commercial horse feeds, ration balancers, supplements, and treats.
