KANDUNGAN NUTRISI AMPAS SAGU (Metroxylon sp) YANG DIAMONIASI UREA DENGAN LEVEL DAN LAMA AMONIASI BERBEDA

Sago waste can used for ruminants feed, but its have lowest crude protein, the crude protein just 0.6 %. Ammoniation can improve the crude protein of sago waste. The research was conducted during October-December 2013 in the Laboratory Nutrition Science and Chemistry Faculty of Agriculture and Animal Science of the State Islamic University of Sultan Syarif Kasim Riau Pekanbaru. This research used differnet levels of urea and times ammoniation. Urea levels were used at 0, 5, and 10 %, times ammoniation used were 0, 10, and 20 days, each treatment was repeated 2 times. Research using completely random design with a factorial combination of 3 x 3 x 2. Data were analyzed with analysis of variance and if its having an effect will be tested by Duncan 's Multiple Range Test. The research result shows the levels of dry matter (DM) 83.61%-87.49%, crude protein (CP) 0.7%-10.90%, crude fiber (CF) 7.88%-13%, extract eter (EE) 0.5%-1%, Ash 3.64%-4.33%, nitrogen free extact (NFE) 75.10%-85.26%. Interaction between times ammoniation and urea levels only at crude protein and NFE by product of sago ammoniation
