Valores Energéticos e Nutricionais do Feijão Guandu para Frangos de Crescimento Lento.

Abstract

The objective of this work was to determine the coefficients of apparent metabolizability of dry matter, crude protein, crude energy and apparent metabolizable energy EMA and apparent corrected for the nitrogen balance EMAn of the pigeon pea for slow-growing chickens using the total collection method of the excreta. We used 100 birds of 21 days of age, distributed in metabolic batteries. The experimental design was the completely randomized (DIC), with two treatments: Ration reference and test feed (70% of the reference + 30% inclusion of pigeon pea) five replicates and ten birds per experimental unit. The experimental period was 7 days, with 4 days of adaptation to the diets and 3 days of total collection of excreta, during that period the feed consumption was also recorded, at the end of the experimental period, samples were taken from the rations and excreta for analysis. The pigeon pea presented 88,528 MS, 22,040 PB, 3756,27 EB, 2,785 EE. The determined values of EMA and EMAn were 2204.00 and 2197.00 respectively. The metabolizable coefficients of dry matter (CMMS), crude protein (CMPB), and crude energy (CMEB) of pigeon pea were 58.43, 28.92 and 60.94, respectively.
