Metabolizabilidade do farelo de banana e moringa para frangos de crescimento lento

Abstract

The study was conducted in the poultry sector, on the campus of the Federal University of Northern of Tocantins, where the survey and analysis of data were performed in order to determine the nutritional values and apparent metabolizability coefficients of dry matter (CMDM), ether extract (CMEE), crude energy (CMCE), apparent metabolizable energy (AME) and metabolizable energy corrected for nitrogen balance (AMEn), banana bran and moringa. We used 84 slow-growing chickens, mixed lot (bare red neck), from 1 to 30 days old. The design was completely randomized with two treatments, six replicates and seven birds per experimental unit. The experimental period was seven days, four of adaptation to experimental diet and three of collection of excreta. At the end of the experimental period was analyzed the chemical composition, metabolizability coefficients, apparent metabolizable energy and corrected for nitrogen balance of banana and moringa bran for slow-growing chickens. It was observed in the chemical composition of banana and moringa bran in dry matter, ether extract and gross energy, 88.89%, 4.71%, and 4141.407 kcal /kg, respectively. The metabolizability coefficients of banana and moringa bran were 53.40% DM, 62.27% CE and 41.09% EE. The AME and AMEn values of banana and moringa bran were 2695 kcal /kg and 2440 kcal /kg in the dry matter, respectively. It is possible to use these foods in the nutrition of slow-growing birds with levels that do not compromise the digestibility of food.
