Abstract：In orderto screen out the better combination ofbacteriaand enzymes for fermented rice straw，in this experiment rice straw silage was randomly divided into 5 groups ： CK group （0.1g⋅kg-1 Bacillus subtilis and Lactobacillus），CH group （0.5g⋅kg-1 cellulase， 0.5g⋅kg-1 hemicellulase and 0.1g⋅kg-1 Bacillus subtilis and Lactobacillus），L group（laccase 1g⋅kg-1 and 0.1g⋅kg-1 Bacillus subtilis and Lactobacillus），CHL group（1 g⋅kg-1 cellulase，hemicellulase，laccase compound enzyme preparation and 0.1g⋅kg-1 Bacillus subtilis and Lactobacillus），U group （ 3% urea and 0.1g⋅kg-1 Bacillus subtilis and Lactobacillus）. After 45 days，the bags were opened for analysis.The results showed that the contents of neutral detergent fiberand acid detergent fiber in CH，L and CHL groups were significantly lower than those in CK group （ ⋅P<0.05 ）.The crude protein content of CH and U groups was significantly higher than that of CK group （ ⋅P<0.05） .Compared with CK group，the total gas production of each experimental group at 72h increased significantly （ . The contents of volatile fatty acids and total volatile fatty acids in the experimental group werealso significantly increased（ P<0.05） . It can be seen that diferent bacterial enzyme treatments under the conditions of this experiment can improve the nutritional value of rice straw，and the CH group has the best effect.
