Abstract
Apparent digestibility of passion fruit seeds (PFS) was estimated in 5 adult sheep, mean liveweight 36 kg, kept in metabolism cages and given diets of Melinis minutiflora hay without or with PFS 8, 16, 24 or 32%. Intake of ME was 87.57, 89.02, 88.49, 78.22 and 77.36 kcal/kg0.75 for the 5 diets, respectively. Intake of DE was 99.05, 101.60, 102.06, 87.01 and 86.78 kcal/kg0.75. Digestibility of CP and nitrogen balance, which was positive for all treatments, were not significantly affected by the amount of PFS in the diet. Digestibility of gross energy was 47.32, 43.75, 42.09, 45.34 and 44.19%, respectively. Digestibility of ether extract was 40.91, 63.46, 59.00, 70.93 and 84.92%.
