Horse feeders are always concerned about the amount and kind of feed to give their horses. Many variables can affect a horse's nutritional needs: A) temperament and disposition, B) present condition, C) age, D) body type and weight, E) production stage (how many hours a day the horse is ridden, pregnancy, lactation), and F) climatic conditions.

Knowledge about the nutritional requirements of horses is not as comprehensive as for cattle or swine. The nutritional requirements of a light horse may differ from those of a draft horse due to differences in disposition and temperament and particularly the peak energy demands of a horse ridden at fast gaits.
