Study on the utilization of passion fruit peel silage was conducted in twenty growing native male sheep. The animals were subjected to the four different feed groups consisted of: (1) fresh grass, (2) passion fruit peel ensiled with 1 percent urea, (3) passion fruit peel ensiled with 2 percent rice bran, and (4) passion fruit peel ensiled with 2 percent ground corn. The feeding period was 112 days. The nutritive content of passion fruit silages were quite similar when ensiled with different materials. However, the ensiling of passion fruit peel with rice bran and ground corn tended to increase DM, EE and NFE contents but reduced CF and ash contents of the silages. The ensiling with urea increased CP content but depressed EE and NFE contents, and also depressed EE and NFE digestibities of silage significantly. Digestion coefficients of DM, CP and CF of silages were not different when ensiled with urea, rice bran and ground corn. The liveweight loss of sheep fed urea-included, rice bran-included and ground corn-included passion fruit peel silages were not significantly different (P0.05), being 0.059, 0.035 and 0.020 kg/d, respectively. The animals fed fresh grass gained their body weight by 0.055 kg/d which was higher (P0.01) than that fed passion fruit peel silages. However, animals fed by ground corn-included passion fruit silage tended to consume more dry matter than the other silages. The carcass characteristic showed also the same trend, being high in animal fed ground corn-included passion fruit silage.
