It was evaluated four crude protein (CP) levels in diets considered as commercial fed to barrows in the growing and finishing phases. A total of 48 barrows, from the same genetic strain, averaging initial weights of 30.8 ± 0.12 kg (growing phase) and 61.2 ± -0.89 kg (finishing phase), segregated in the production system, was used. The animals were allotted to randomized blocks design, composed of four treatment (level of CP) and six replications and two animals per experimental unit. […]
