Digestibilities of sweet corn stoven which after fresh ear harvesting was ensiled with 10 persent rice bran (SCSS) was found to be a good quality silage (pH 3.9-4.1). It contained higher crude protein, in vitro organic matter digestibelity and metabolizable energy than Ruzi grass or UTS but had lower cell wall content, ligno-cellulose and lignin than the other two roughages. The voluntary dry matter intake of the 3 groups was 2.3, 2.4 and 2.9 kg./d. The digestiblity of dry matter and organic matter in SCSS were higher than those in Ruzi grass and UTS. SCSS had similar protein digestibility as Ruzi grass, but higher than UTS NDF and ADF digestibilites of SCSS were equal to UTS but higher than Ruzi grass. Dry matter and organic matter digestibilities of group I (SCSS) were similar to group II (Ruzi grass) but higher than group III (UTS). In an increased intake of digestible dry matter and digestible organic matter in the first 2 groups. Crude protein digestibility in group II was similar to that in group II but lower than that in group I. This led to their lower digestible crude protein intake. Average daily gain and feed conversion ratio of group I was better than the other two groups. Feed cost per kg. weight gain of the three groups were similar. Sweet corn stover can be well preserved by ensiling with 10 percent rice bran. The silage had higher nutrient content and consequently provided better performance of growing cattle than Ruzi grass or urea-treated rice straw
