Twenty-seven week-old commercial laying hens were allotted to a completely randomized design with a 3×3 factorial arrangement with three replicates of six birds per treatment. The factors consisted of hree methods for estimatingamino acid ingredient composition (Brazilian tables, prediction equations and factor for correcting amino acid in function of ingredient protein level) and three amino acid recommendations, being two for digestible amino acids and one for total amino acid. Methods for estimation amino acid ingredients composition had effect only on […]

A trial was carried out to evaluate the effect of low crude protein (CP) diets, supplemented with amino acids, on the starting barrows performance. Forty barrows genetically improved, of commercial dam line, were allotted to an experimental randomized complete block design, with four treatments, five blocks and two animals per experimental unit. The four treatments were: 18.73% P .96% L – corn-soybean meal diet containing 18.73% of CP and 0.96% of digestible lysine; 16.86%P + L – it was constituted […]
