Adapt the fodder to its work and its physiological state
In the wild, the horse’s diet consists exclusively of grass (70% grasses, 20% legumes and 10% various plants).
But when a horse is in stable, its diet must include fodder (hay or alfalfa), cereals (oats, barley, corn, etc.) and straw.
Several factors need to be taken into account when defining nutritional needs: race, sex, height, outside temperature, work (physical activity) and physiological state (pregnant or nursing mare).
