A horse needs enough protein to stay healthy and well, to be able to work efficiently and to increase muscle mass. The need for protein is regulated by the horse's physiological needs. Foals and pregnant mares need more protein than a full-grown horse. Horses that move more need more protein than horses that are at rest. Horses that work very hard have the greatest need for energy and protein. Approximately 20% of muscle mass is protein. The most essential amino acids for horses are lysine and methionine.
