Resumo
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).
