Uso da farinha de folhas de moringa oleifera na alimentação de frangos de corte

Abstract

Moringa oleifera A (MOL) has characteristics that make it a potential candidate to be used as an alternative food in the feeding of poultry, such as good protein, the presence of bioactive compounds, minerals and vitamins. Thus, this study aimed to determine the energy and nutritional values of MOL, there was a digestibility trial with chickens. Were used 90 male chicks of Cobb-500 strain with 14 days old, that were housed in metabolic cages according to an entirely causalizado design, with five treatments, six replicates three birds each. The treatments consisted of: a diet reference and four test diets where the leaves of moringa grinded replaced based on natural matter, 10%, 20%, 30% and 40% of the reference diet. The trial period was eight days (four of adaptation and four excreta collection). Data were submitted to analysis of variance and regression analysis at 5% probability. From the regression analysis was determined the apparent metabolizable energy (AME), apparent metabolizable energy corrected for nitrogen balance (AMEn), apparent metabolizable coefficient of dry matter (AMCDM), apparent metabolizable coefficients of crude protein (AMCCP), apparent metabolizable coefficient of gross energy (AMCGE) bran moringa oleifera. It was observed an increase in metabolizable energy of rations as the MOL replaced the reference diet. In the derivation of regression equations the level that provided the best value of EME, AMEn, AMCGE was 37.7% substitution. The leaves meal MOL had an average of 3140 kcal / kg of AME, 2845 kcal / kg AMEn, 76.92% of AMCGE, 76.63% of AMCDM and 73.42% of AMECCP.
