Abstract

ABSTRACT: An experiment was carried out to determine the nutritional requirements of crude protein in light post-peak production poultry during the first lay cycle. Three hundred 38 weeks old Hy Line W36® hens were used for the experiment, distributed in an experimental design unreservedly at random with five treatments, five repetitions and 12 hens for experimental unit. The birds were fed with a basic diet including corn, sorghum, and soybean cake, with 2,800 kilocalories of EM/kg, and five levels of PB (14, 15, 16, 17 and 18%). Meaningful statistic differences were not observed (P>0,05) in egg production, egg mass, food consumption, nutritional conversion and birds corporal weight increase of the birds that underwent the different treatments. As a consequence, the productive performance of the birds is not related with the level of raw protein only if the adequate levels of energy and limiting amino acids are guaranteed.
