Effect of varying levels of leucine and energy on performance and carcass characteristics of broiler chickens

The experiment was conducted to evaluate the influence of excess leucine, in broiler diets containing varying levels of energy. In a 2 x 2 factorial arrangement, the effects of leucine levels and dietary energy on performance and carcass characteristics of Cobb broiler chickens from 3 to 6 weeks of...
