A study has been conducted to evaluate nutrient composition of young coconut husk silage fermented with rice bran. The study has been conducted in the State Agricultural Polytechnic of Kupang for seven months. A completely randomised design with four treatments and five replicates was utilised. The treatments were young coconut husk with no rice bran (P0) or the husk plus 4% (P1), 8% (P2), 12% (P3) of total weight of the silage. Variables measured were concentrations of dry matter, ash, crude protein, crude fat and crude fibre. Analysis of variance showed that inclusion of rice bran significantly (P<0.01) increased all variables measured with the highest rate was recorded for inclusion of 12% rice bran. It can be concluded that to increase nutrient composition of young coconut husk silage is to include 12% of rice bran to the silage materials. Key words: Rice bran, nutrient composition, young coconut husk, silage
