There are several type of the weeds that are potential as feed in livestock integration system but less study were conduct to determine the dry matter yield and chemical composition of the weeds. The objectives of this study is to determine the dry matter yield and chemical composition of the weeds found in integrated farming. There are two dominant weeds species during the sampling process: Slender Panic grass/Pait grass (Ottochloa nodosa) and Asystasia grass (Asystasia gangetica). Both cut weeds were weighed to determine the yield. Samples were sent to laboratory for proximate analysis. Study showed that, the dry matter for Slender Panic grass and Asystasia grass are 21.5% and 11.5% respectively. While the dry matter yield for Slender Panic grass is 216 kg/acre, lower than Asystasia grass, which is 587 kg/acre. Meanwhile, the results of the chemical compositions found that TDN and ME of Asystasia grass were higher than the Slender Panic grass. TDN value for Slender Panic grass is 52.3% and Asystasia grass is 55.7%. Metabolism Energy value for Slender Panic grass is 7.72 MJ/kg and Asystasia is 8.28 MJ/kg. Asystasia grass contain higher CP value which is 23.5% compare to 20.2% in Slender Panic grass. Based on this study, dry matter yield of Slender Panic grass is relatively low compare to Asystasia grass. While, the chemical composition of the weeds analysed in this study, contains high nutritional value and could fulfilled the livestock requirement.
