摘要: This study aimed to evaluate the performance of laying hens subjected heavy semi-low crude protein (14.0%) and lysine levels while maintaining same relation digestible amino acid/ lysine. A commercial line 420 Isa Brown hens, in period from 28 44 weeks age, were distributed 42 experimental plots. completely randomized design with six treatments seven replicates four periods days/each was used. The were: Control - Formulated according nutritional requirements proposed strain, containing 16.92% protein, 0.750% Treatments 1 5, 14% 0.600% lysine, 0.675%, 0.750%, 0.825% 0.900%, respectively. requirement other acids, can be estimated at diet which corresponds average daily intake 876 mg dig. hen-1 day-1, without compromising hens.
