Utilization of passion fruit peel silage as supplementary feed for growing beef cattle in dry season was studied. There were four feeding groups, namely; rice straw and urea-treated rice straw, rice straw and passion fruit peel silage, rice straw and passion fruit peel ensiled with 1 % urea and rice straw and passion fruit peel ensiled with 2 % rice bran, as treatment 1, 2, 3 and 4, respectively. Animals were fed for 98 days. The passion fruit peel on the surface showed about 15-20 % spoilage after 2 months of ensiling Nutrient content, particularly protein, increased slightly in passion fruit peel ensiled with urea or rice bran. The average daily gains of cattle in treatment 1, 2, 3 and 4 were 152, 148, 200 and 204 g/head/day, respectively and these were not significantly different. However, dry matter intake of cattle in treatment 1 was higher than the others. Although the digestion coefficients of dry matter were not different, the digestion coefficient of protein in treatment 2 was higher than the others. Passion fruit peel silage can be used as cattle feed without any ill effects. Only suitable for farmers who live near the factory since the transportation cost might be a problem for farmers living further away
