Abstract This study was to determine the fermentation quality of a mixture of corn steep liquor (CSL) (178?g/kg wet basis) and air-dried rice straw (356?g/kg wet basis) after being treated with inoculants of different types of lactic acid bacteria (LAB). The treatments included the addition of no {LAB} additive (control), which was deionized water; homo-fermentative {LAB} alone (hoLAB), which was Lactobacillus plantarum alone), and a mixture of homo-fermentative and hetero-fermentative {LAB} (he?+?hoLAB), which were L.?plantarum, Lactobacillus casei, and Lactobacillus buchneri. The results showed that the inoculation of the mixture of {CSL} and air-dried rice straw with he?+?hoLAB significantly increased the concentration of acetic acid and lactic acid compared with the control (P?372?h. The control group was the first to spoil, whereas the silage treated with he?+?hoLAB remained stable throughout the 372?h period of monitoring. The results demonstrated that the he?+?hoLAB could effectively improve the fermentation quality and aerobic stability of the silage.
