    O presente estudo foi conduzido para avaliar a influĂȘncia da inclusĂŁo do resĂ­duo do processamento de abacaxi (Ananas comosus L.) nas dietas sobre os consumos (por unidade de tamanho metabĂłlico - UTM) e coeficientes de digestibilidade da matĂ©ria seca (MS), matĂ©ria orgĂąnica (MO), proteĂ­na bruta (PB), extrato etĂ©reo (EE), fibra detergente neutro (FDN), fibra detergente ĂĄcido (FDA), hemiceluloses (HCEL), celulose (CEL) e energia de dietas experimentais isofibrosas e isoprotĂ©icas. Avaliaram-se tambĂ©m os balanços nitrogenados e de energia dos animais. Vinte ovinos machos, inteiros receberam raçÔes com quatro nĂ­veis de inclusĂŁo do resĂ­duo (0; 11%; 16%; 27%) em base de matĂ©ria seca, em delineamento inteiramente ao acaso, com cinco repetiçÔes por tratamento. Maiores consumos de matĂ©ria seca foram evidenciados quando as raçÔes continham 11% do resĂ­duo. Maiores consumos de proteĂ­na bruta, fibra detergente neutro, fibra detergente ĂĄcido e celulose (g/UTM) e energia metabolizĂĄvel (kcal/UTM) foram apresentados por animais alimentados com dietas contendo 11% de resĂ­duo em relação ao das dietas com 27% de inclusĂŁo (PThe influence of increasing levels of pineapple by-product (Ananas comosus L.) on intake (unit metabolic size - UMS) and apparent digestibility (%) of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicelluloses (HCEL) and cellulose (CEL) and energy of isofibrous and isoproteic experimental diets of sheep were evaluated. Energetic and nitrogenous balance were also measured. Twenty rams were randomly allotted to four treatments in a completely randomized design with five replications. The treatments were formulated to contain zero; 11, 16 and 27% of pineapple by-product on DM basis. Higher dry matter intake was observed on 11% pineapple by-product diet. CP, NDF, ADF, CEL intake (g/UMS) and metabolizable energy intake (kcal/UMS) of 11% pineapple by-product diet were higher than 27% pineapple by-product diet (P<0.05). ADF digestibility was higher for 0% pineapple by-product diet. Energy and nitrogenous balances were positives. Diets formulated to contain up to 16% of pineapple by-product presented the best results
