Alfalfa is an important component of an active horse's diet. Safely fed to horses for thousands of years, Alfalfa's high protein, fiber, vitamin and mineral content all contribute to its high feed value. A horse fed Alfalfa as part of its daily ration will meet its need for protein while receiving essential vitamins and minerals. The high protein and mineral needs of young, growing horses and lactating mares make Alfalfa an important part of any feeding program. Alfalfa's high palatability ensures that even the pickiest of eaters will maintain the proper balance in their diet.
