Abstract

The experiment was carried out in order to evaluate rations with different levels of digestible lysine, maintaining ratio with met+cys, threonine and tryptophan amino acids, for broilers chickens in the starter period (one to 21 days of age). Four hundred male broilers chickens Cobb Vantress were used in experimental design completely randomized with four treatments (1.14%; 1.18%; 1.22% and 1.26% of digestible lysine), four replicates and 25 birds per experimental unit. It was observed quadratic effect (P<0.05) of lysine levels on weight gain and feed conversion of birds, being the better level 1.183% and 1.190% of digestible lysine, respectively. It was not verified effect of treatments on feed intake, abdominal fat, corporal chemical composition, uric acid levels on blood and litter moisture and nitrogen rate. According to the performance results, can be concluded that the digestible lysine requirements for male broiler chickens in the period from 1 to 21 days of age were of 1.19%.

KEY WORDS: Broiler chickens, digestible lysine, ideal protein.
