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 […]
