Zusammenfassung: | This trial was conducted to evaluate the effect of increasing levels of coconut cake (Cocos nucifera L.) on feed intake and apparent digestibility of dry matter, neutral detergent fiber and acid detergent fiber. We used 16 non-castrated sheep with mean body weight of 28 kg (± 3.2 kg), distributed in a completely randomized design with four treatments (0, 0.4, 0.8 and 1.2% BW of inclusion of coconut pie) and four replications. There was a trial period of 21 days with 14 days of adaptation and 7 days of data collection, which monitored the supply of diet and total fecal collection. The apparent digestibility of dry matter and acid detergent fiber effects were linear and increasing with the inclusion of coconut cake in the diet (44.9 to 57 and from 30.57 to 40.32%) to levels of 1.2% inclusion, respectively. Neutral detergent fiber showed a quadratic response, with the best level of 0.89% and maximum digestibility of NDF of 59.39%. Coconut cake is an excellent source of supplemental feed, and can contribute in meeting the nutritional demands for meat and milk production in the eastern Amazon. Keywords: Amazon, metabolism assay, supplemental feeding. Foi avaliado o efeito da inclusao de niveis crescentes de torta de coco (Cocos nucifera L.) sobre a ingestao de alimentos e a digestibilidade aparente da materia seca, da fibra em detergente neutro e da fibra em detergente acido. Foram utilizados 16 ovinos nao-castrados, com peso corporal medio de 28 kg (± 3,2 kg), distribuidos em delineamento inteiramente casualizado, sendo quatro tratamentos (0; 0,4; 0,8 e 1,2% PV de inclusao de torta de coco) e quatro repeticoes. Houve um periodo experimental de 21 dias com 14 dias de adaptacao e sete dias de coleta de dados, em que se monitorou o fornecimento da dieta e a coleta total de fezes. A digestibilidade aparente da materia seca e da fibra em detergente acido apresentou efeitos lineares e crescentes com a inclusao da torta de coco na dieta (44,9 a 57 e 30,57 a 40,32%) para os niveis de 1,2% de inclusao, respectivamente. A fibra em detergente neutro apresentou comportamento quadratico, e o melhor nivel de inclusao ocorreu com 0,89% e digestibilidade maxima da FDN de 59,39%. A torta de coco e uma excelente fonte de suplementacao alimentar e pode contribuir no atendimento das demandas nutricionais para producao de carne e leite na Amazonia Oriental.
