Effects of Lactobacillus and cellulase on the quality of corn straw silage

In order to know about the effects of different microbial preparations on the quality of corn straw silage, high-moisture content of spring corn straw was used as raw materials to carry out fermentation of silage by adding different percentages of Lactobcillus and cellulase. The results showed that during the fermentation process of corn silage, adding Lactobcillus and cellulase could effectively decrease the decay rate of silage, improve and increase the quality and nutrient value of silage, and the effects of 0.30% cellulase was the best, the decay rate of silage was below 1.4%, the content of crude protein was 3.49%, the ratio of ammonia nitrogen to total nitrogen [m(VBN)/m(TN)] was 6.60, the content of butyric acid was 0, the content of neutral detergent fiber was 11.48% and acid detergent fiber was 7.02%, and the content of acid lignin was 1.42%. Therefore, screening and adding suitable and proper microbial preparations were the effective measures to improve the quality of corn silage.
