ABSTRACT

Avaliou-se o consumo, a digestibilidade, e o desempenho de silagens de capim-elefante, contendo diferentes níveis de inclusão (0; 10; 20 e 30%) de casca de maracujá desidratada na matéria natural do capim-elefante, em um delineamento inteiramente casualizado, com 4 repetições. O capim elefante foi cortado com 60 dias de idade, picado e ensilado em tonéis juntamente com as proporções de casca de maracujá desidratada conforme cada tratamento. Após 30 dias de armazenagem os silos foram abertos para avaliações. Observou-se que a inclusão do resíduo influenciou o consumo e a digestibilidade de alguns nutrientes (P<0,05). Houve efeito para o ganho de peso médio diário e ganho total dos cordeiros, sendo que para cada 1% de casca de maracujá desidratada adicionada elevou-se 2,42% o GMD. A conversão alimentar apresentou efeito linear decrescente (8,9; 9,2; 8,6 e 7,2), respectivamente, entre os tratamentos, permitindo concluir que, a casca de maracujá desidratada pode ser utilizada em até 30% de inclusão ao capim-elefante.


The consumption, digestibility, and performance was evaluated of lambs fed silage elephant grass containing different inclusion levels of passion fruit peel dried (0, 10, 20 and 30%) in natural matter of elephant grass, in a randomized completely randomized design with four replications. The elephant grass was cut at 60 days of age, chopped and ensiled in barrels along with the proportions of dried passion fruit peel, according to each treatment. After 30 days, the silos were opened for evaluation. It was observed that the inclusion of the residual affected the intake and digestibility of certain nutrients (P<0.05). Effect was observed for average daily weight gain and total gain of the lambs, and for every 1% of dried passion fruit peel added the ADG increased 2.42%. The feed conversion showed decreasing linear effect (8.9, 9.2, 8.6 and 7.2), respectively, among treatments. It is concluded that the dried passion fruit peel can be added up to 30% of the elephant grass.
