One experiment was carried out to evaluate the use of cottonseed meal (CM42) on growing-finishing pigs feeding and the effect on performance, carcass traits and economic feasible. Were used 40 crossbred pigs, with body weight of 29.7 ± 1.6 to 52.2 ± 3.6kg in the growing and 52.7 ± 2.9 to 86.9 ± 5.0kg in the finishing phase. For each phase were formulated four diets, the first contain no cottonseed meal (0%) and three experimental diets with increasing levels of inclusion (5, 10 and 15%) of CM42. The pigs were allotted in a completely randomized block design with four treatments and four blocks, resulting in four replicates per treatment. No were observed effect of inclusion of CM42 for performance variables in growing phase, however for finishing phase, there were linear effect in performance of levels of inclusion on daily feed intake and feed:gain ratio. No was effect of inclusion of CM42 on carcass traits and plasma urea nitrogen. The CM42 can be used in diets pigs on growing phase in levels up to 15% and to used up to 10% on finishing phase, respectively, or in replaced next 50% in crude protein of soybean meal, without impairing for pigs. However, 5% level of inclusion showed better economic efficiency.
