All horses should have what in their diet?

Other minimum requirements for a horses nutrient include; 8-10% crude protein, 0.3% calcium, 0.2% phosphorus and 1Mcal of digestible energy per pound of the total ration. Typically, good quality hay is enough to ensure a horse is properly fed, so long as it is fed in the correct amount.
