Nutritional evaluation of cottonseed meal in high energy performance and carcass characteristics of broilers

The objective of the research was to determine the chemical and energetic composition of cottonseed meal produced by BUNGE Foods Company, trademark as high energy cottonseed meal (FAAE ®) and to evaluate its inclusion in the performance of broilers. The chemical, energetic and aminoacidic composition was determined using the total excretion gathering method, with two gathers a day. It was used ferric oxide to mark the beginning and the end of the gathering. The level of inclusion of the food testing in the reference diet 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 that were common to all birds. From the ninth day, the birds received an experimental diet with substitution levels of 3%, 6%, 9% and 12% inclusion of cottonseed meal . 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-1 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-1. It was not observed effect in the performance and carcass return of the poultry at 42 days of age.
