This study aims to obtain the best combination of mineral S and P levels on ammoniation palm leaves in order to improve the digestibility of palm leaves as ruminant feed. The study was conducted starting on June 17, 2013 until October 17, 2013. Ammoniated palm leaf samples supplemented with mineral sulfur and phosphorus are subjected to Proximate and Van Soest analysis in Ruminant Nutrition Laboratory of the Faculty of Animal Science Andalas University, Padang. The method used in this study is an experimental method using a factorial randomized block design (3x3) with 3 replications. The first factor is the treatment of mineral Sulfur with 3 levels: S0 = 0.0%, S1= 0.2% and S2 = 0.4% of DM. The second factor is the mineral P in 3 levels, ie P0 = 0.0%, P1 = 0.27% and P2 = 0.54% of the DM. Parameters measured were dry matter digestibility (IVDMD) organic matter, crude protein, NDF, ADF, cellulose, hemicellulose and characteristic rumen fluid: pH of the rumen fluid, the levels of VFA, NH3-N content of rumen fluid.
