This study was conducted to evaluate the effect of the liquid waste from methane fermentation on chemical components, digestible dry matter and net energy of pasture mixtures of orchard grass, tall fescue, Kentucky bluegrass and ladino clover. The total crude proteins and crude ashes increased with the application of liquid waste, but N-free extracts decreased somewhat and it didn't affect the content of crude fat and crude fiber. Amounts of neutral detergent fiber and acid detergent fiber increased with incre1331asing application of liquid waste and the content of cellulose in cell-wall constituents decreased, but hemicellulose increased. The digestible dry matter was produced 405 Kg/10a at optimum application of 42 MT/10a liquid waste compared with NPK check plot of 233 Kg/10a. The starch value and net energy lactation were 291.3 KStE and 3450 MJ-MEL respectively indicating that the optimum application of liquid waste increased their va
