Resumo: The objective of the research was determine chemical and energetic composition of the cottonseed meal and evaluate its inclusion on performance of poultry. The chemical, energetic and aminoacidic composition was determined using the total excreta collection method, twice a day. It was used ferric oxide to mark the beginning and the end of the collection. The level of inclusion of test feed in reference feed was 20%. The performance was evaluated with the inclusion of cottonseed meal in a period of 9 to 42 days. During the first nine days the poultries received pre-initial feed common to all birds. Beginning on the ninth day, birds were subjected to an experimental diet with substitution levels of 3%, 6%, 9% and 12% of the corn and the soy meal of reference feed. The cottonseed meal presented 95,91% of dry matter, 9,8% of fat, 27% of crude protein, 4,6% of ash, 4.867 kcal/kg of crude energy, 1,32% of lysine and 0,35% of metionine. The determined value of apparent metabolizable energy corrected to nitrogen was 1.188 kcal/kg. It was not observed effect in the performance and carcass return of the poultry at 42 days of age.
