Kansas Agricultural Experiment Station Research Reports

Protein is one of the most expensive nutrients in poultry diets. In an effort to minimize feed costs, protein digestion and utilization by the animal must be carried out as effi­ciently as possible. The objective of this experiment was to evaluate the effects of dietary amino acid density and exogenous protease inclusion on growth performance and amino acid digestibility in turkey poults. Hybrid turkey poults (n = 780) were fed diets formulated to provide low (LAA) or adequate (AAA) amino acid density (approxi­mately 91 and 100% of the NRC4 recommended requirement for digestible Lys, respec­tively) with each diet being fed …
