The effects of reducing dietary CP and soybean meal levels on performance, N excretion, organs weight and diarrhea incident were evaluated in pigs supplemented with amino acids. The diets contained four levels of CP (21.0, 19.5, 18.0, and 16.5%) and were supplemented with synthetic amino acid (lysine, metionine and treonine). In experiment I, eight crossbred (LD x LW) castrated males (initial weight = 22 kg) were individually allotted to a randomized block design, with split plot arrangement to determine N […]
