By estimating the pounds of forage an animal is consuming each day, you can use the crude protein analysis to determine if you are meeting the animal’s protein requirements.
Example: Requirement is 1.4 pounds crude protein (CP)/day. We estimate an animal consumes 15 pounds of 6 percent CP hay per day:
15 x 6% = 0.9 lb of CP/day
1.4 lb CP required – 0.9 lb CP from forage = 0.5 lb/day CP deficient from animal’s protein requirement.
