          Abstract

          O objetivo deste trabalho foi determinar a energia metabolizável aparente (EMA) e aparente corrigida (EMAn) da farinha de carne e ossos (FCO) com diferentes granulometrias (grossa, média e fina), em dois níveis de substituição (20 e 40%) para pintos de corte. Duzentos e oitenta pintos de corte com 15 dias de idade foram distribuídos em delineamento inteiramente casualizado, com sete tratamentos (seis tratamentos com farinha de carne e ossos e uma dieta referência), quatro repetições e dez aves por unidade experimental. Os valores médios de EMA para os níveis 20 e 40% de substituição foram 2,60 e 2,27 e para EMAn , 2,50 e 2,14 kcal/g MS, respectivamente. Os resultados, considerando-se as granulometrias grossa, média e fina da FCO, foram 2,13; 2,65; e 2,53 kcal/g MS para EMA e 2,03; 2,56; e 2,37 kcal/g MS para EMAn, respectivamente.

          The objective of this work was to determine the apparent metabolizable energy (AME) and nitrogen-corrected apparent metabolizable energy (AMEn) of meat and bone meal (MBM) with different particle sizes (coarse, medium and fine), in two levels of substitution (20 and 40%) for broiler chicks. Two hundred and eighty broiler chicks with 15 days of age were allotted to a completely randomized design, with seven treatments (six treatments with meat and bone meal and a reference diet), four replicates and ten birds per experimental unit. The AME mean values for the 20 and 40% of substitution were 2.60 and 2.27 and the EMAn 2.50 and 2.14 Kcal/g DM, respectively. The results, considering coarse, medium and fine particle sizes of the MBM, were 2.13, 2.65 and 2.53 kcal/g DM for AME, and 2.03, 2.56 and 2.37 kcal/g DM to AMEn, respectively.
