An experiment was carried out to evaluate performance, development of digestive organs of young broiler chicks (one to twenty-one days of age) fed diets with different levels of digestible lysine in pre-starter diet (1 to 7 days old). A total of 480 day old Cobb 500 male chicks allotted in brooded batteries in a randomized block design with four levels of digestible lysine (1,050, 1,200, 1,350 e 1,500 %) with 10 replicates of 12 chicks each. Weight gain, feed intake, feed: gain ratio and development of digestive organs were evaluated. For statistical analysis the program SAEG developed by the Federal University of Viçosa (UFV) was used. Analysis of polynomial regression was done for digestile lysine levels. No significant effect on broiler performance. Digestible lysine recommended for male broilers was 1,050% in pre-starter diet (1 to 7 days old).
