Relationship between Starch and Amino Acid Levels of Broiler Diets on Growth Performance and Feed Efficiency

Abstract

This study was conducted to investigate the relationship between starch and amino acid levels of broiler diets on growth performance and feed efficiency. In this study, 240 one-day old chicks were distributed to 6 treatments using a completely randomized design (CRD) with four replications. Three treatments were fed with high starch and three others were fed with low starch. Both type of diets were formulated as isocaloric with three levels of total lysine, varying from 1.34%, 1.43%, 1.48% for starter period (0-18 days) and 1.18%, 1.3%, 1.35% for finisher period (19-35 days). The result showed that high starch level increased body weight gain (p
