Ideal Protein

Ideal protein can be described operationally as protein that cannot be improved by any substitution of a quantity of one AA for the same quantity of another. Any departure from a desirable pattern of AA can result in, among other things, a reduced efficiency of AA utilization and a concomitant increase in N excretion. Although the efficiency of AA utilization in commercial food animal production can be enhanced in several ways,[3] using various protein sources with complementary AA compositions or supplementing diets with crystalline AA to simulate the ideal pattern would be more practical means to incorporate this concept.
