Contribution of protein, starch, and fat to the apparent ileal digestible energy of corn- and wheat-based broiler diets in response to exogenous xylanase and amylase without or with protease

This paper shows that the caloric contributions of starch, fat, and protein in response to exogenous enzymes were affected differentially by the base grain (corn or wheat) and the presence of fibrous ingredients at 21 and 42 d of age. Evidently, there is an opportunity for greater accuracy in the development of energy matrices for exogenous enzymes, reflecting the diet composition and physiologic status of the birds, which can allow producers to maximize the value of these additives in their systems.
