Fiber Sources for Horses

View nutrition analyses for fiber sources used in horse feed ingredients in the Mad Barn Equine Feed Database. This category includes dietary fiber ingredients that contribute fermentable energy to the equine diet, such as beet pulp, soy hulls, alfalfa meal, hay, grass, oat hulls, wheat middlings, and other forage- or plant-based fiber sources.

Compare nutrient profiles for different fiber sources to understand their calorie contribution, digestibility, neutral detergent fiber, acid detergent fiber, starch and sugar levels, and role in supporting gut health, hindgut fermentation, body condition, and steady energy intake.
