title: Performance of chicks fed diets formulated to minimize excess levels of essential amino acids.
abstract: Studies were conducted in which levels of essential amino acids in excess of the minimum requirements were minimized in broiler diets composed of commercially available feed stuffs and synthetic amino acid supplements. Growth rate and efficiency of feed utilization of chicks fed such diets were equal to that attained by chicks fed diets formulated by conventional means when grown under conditions where heat stress was not a factor and significantly improved when fed under conditions of heat stress. Improvements were obtained in efficiency of protein and calorie utilization using this technique of formulation.
