Abstract in Portuguese
Foi estudada a possibilidade de uso da semente de maracujá (Passiflora edulis, Sims. forma flavicarpa, Deuger) na alimentação de ruminantes. Oito carneiros adultos foram usados para medir a digestibilidade de quatro raçoes estabelecidas a partir de uma dieta básica constituída de 700g de feno de Rhodes (Chloris gayana) mais 100g de torta de algodão, na qual se substituiu zero, 100, 200 e 300g do feno por semente de maracujá. Mediu-se ainda a digestibilidade desta última, por diferença. A elevação dos níveis de semente de maracujá foi acompanhada, na dieta total, por decréscimo na digestibilidade da matéria seca (62,6 para 52,0%), fibra bruta (69,1 para 32,9%) e extrativo não nitrogenado (62,6 para 56,4%); aumento na digestibilidade da proteína bruta (64,8 para 72,3%) e extrato etéreo (44,5 para 76,7%). A digestibilidade da semente de maracujá foi afetada por seus níveis crescentes na dieta, havendo decréscimo de digestibilidade da matéria seca (56,0 para 36,0%), extrativo não nitrogenado (74,5 para 36,2%) e extrato etéreo (94,0 para 81,1%). A digestibilidade da proteína (média de 89,1%) e fibra bruta (média de 10,5%) não foi afetada. O valor médio de NDT da semente de maracujá, considerados os três níveis, foi 64,88%.

Abstract in English
Eight mature sheep were used in digestibility trials to evaluate the use of Passion fruit seed (Passiflora edulis, Sims. forma flavicarpa, Deuger) as a feed ingredient for ruminant rations. The animals were fed a basal ration of Rhodes grass hay (Chloris gayana) and cotton seed meal; the seed replaced 0, 100, 200 and 300g of hay, respectively, in the four treatments. Total diet dry matter (62.2 to 52.0%), crude fiber (69.1 to 32.9%) and nitrogen free extract (N F E) (62.6 to 56.4%) digestibilities, were lowered, whereas crude protein (64.8 to 77.3%) and ether extract (E E) (44.5 to 76.6%) digestibilities were enhanced by increasing levels of the seed in the diet. The seed dry matter (56.0 to 36.0%), N F E (74.5 to 36.2%) and E E (94.0 to 81.1%) digestibilities were lowered, whereas crude protein (89.1%) and crude fiber (-10.5%) were unchanged by increasing levels of the seed in the diet. The estimated T D N value of the was 64. 9%.
