This study aimed to evaluate effect of jackfruit leaves (JF) replacing for Para grass (PG) on intake, digestibility, nitrogen balance and ruminal fermentation in growing meat goats. Four male Boer goats, 4 months old, were used in a 4×4 Latin square design. A basal diet consisted of pelleted concentrate and PG (C:F 30:70). The treatments were 4 levels of JL (0, 50, 75 and 100%) replacing PG on a DM basis (equivalent to: 0, 36.9, 52.7 and 70.3% of diet DM on basis of actual intakes during the experiment). Result showed that replacement of JL for PG in the diets increased (p
