aValues adapted from the National Academies of Sciences, Engineering, and Medicine. Nutrient Requirements of Beef Cattle. 8th rev. ed. National Academies Press; 2016, calculated for an animal with an unshrunk mature weight of 1,400 pounds (635 kg). Metabolizable protein should not be confused with crude protein, as these values are not equal to one another. Dietary crude protein requirements of growing and finishing cattle can be found in the table Crude Protein Requirements of Growing and Finishing Beef Cattle.
