A horse's daily nutrient needs will vary because of several factors, including age, activity or performance level, health status, and, in broodmares, stage of pregnancy or lactation. Estimates of dietary requirements can be found in a variety of publications, such as the National Research Council's Nutrient Requirements of Horses, 6th Edition (NRC, 2007), in extension publications such as, on websites such as, or in materials produced by state extension specialists or equine nutritionists.
