Abstract: The effects of withered Alhagi sparsifolia and rice straw mix-ensiling on silage quality were studied. Silages of withered A. sparsifolia, rice straw and their mixture were sensorially evaluated and silage samples analyzed for pH, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acetic acid (AA), propionic acid (PA), butyric acid (BA), lactic acid (LA) and total acid (TA). A. sparsifolia was ensiled successfully, although it was leguminous herbage, and homolactic fermentation was dominant. After A. sparsifolia and rice straw mix-ensiling, water soluble carbohydrates (WSC) in the ensilaged raw material were increased (P<0.05). Ammonia nitrogen/total nitrogen and pH were significantly reduced (P<0.01), while lactic acid (LA), propionic acid (PA) (P<0.01) and total acid (TA) content (P<0.05) increased. Butyric acid (BA) (P<0.05) was reduced when the A. sparsifolia content of the mixture exceeded 40%, and silage quality was improved.
