The effects of different levels of black oats in diets for swine in growing and finishing period were studied at the Trainning Conter of COTRIJUÍ in Augusto Pestana, RS. The experiment was conducted with 40 animals of Wessex breed, with initial average weight of 26.5kg, distributed in 4 x 2 factorial arrangement (0, 15, 30 and 45% of oats black x 2 sexos). The experimental design used was the completely randomized with 3 repetition. The water and diet were given ad libitum. In both phases, were estimated feed consumption, average daily gain and feed conversion. After the slaughtering, the carcass were classified and calculated the carcass yield, the carcass lenght, the mean backfat thickness, ham percentage, área of the Longissimus dorsi and relation meat-fat. There were no significant difference (P > 0.05) between the treatments for performance and carcass characteristics. In the finishing and total periods, the difference between sex statistically significant (P < 0.05) for the average feed consumption and daily gain, favoring the barrows. There were significant differences (P < 0.05) between sex for the mean backfat tickness and relation meat-fat, favoring the female. The results show that black oats could be utilized in the swine diets up to a level of 45% in the growing and finishing periods, without interference in the swine performance and in the carcass characteristics.
