Keratinase in starter diets improves growth of broiler chicks.
The objective of this study was to determine the efficacy of a broad-spectrum protease enzyme, PWD-1 keratinase, upon supplementation to corn-soy starter diets on growth performance of broiler chickens. Three experiments were conducted. In each experiment, 1-d-old broiler chicks were randomly assigned to 24 cage pens of eight birds per pen in a completely randomized design of five experimental ...
