Ruminant feed processing technology is really needed in an attempt to increase the quality of Benggala (Panicum maximum) grass and other waste products. One of new local feed resources in North Sulawesi categorized as waste product is Sago waste which is abundantly available and has a big potential in providing animal feedstuffs. The present study was designed to evaluate the utilization of urea and optimal incubation time to produce the best nutritive quality when added to ammoniated Benggala grass. A Pleurotus ostreatus fungus was used to determine the optimal incubation time to produce the best quality of Sago waste. Research results showed that the best quality of ammoniated Benggala grass was seen at the addition of 6% urea with an incubation time of 21 days, as indicated by the increasing of crude protein, cellulose, and hemicelluloses. The best nutrient quality of Sago waste fermented with Pleurotus ostreatus was shown at incubation time of 30 days, as indicated by significantly (P< 0.01) increasing in protein content and the decreasing of lignin of Sago waste. Nutritive value evaluation of ammoniated Benggala grass and fermented Sago waste as fed showed a significant (P< 0.01) increase in dry matter and organic matter digestibility in vitro. It can be concluded that nutritive value of determined ammoniated Benggala grass and fermented Sago was increased as well asdry matter and organic matter digestibility in vitro.
