How do I use a forage crude protein analysis?

Last Updated: February 19, 2008

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.
