Feed for improving cattle rumen degradation rate and application thereof

The invention belongs to the technical field of biological feeds, and particularly relates to a feed for improving the cattle rumen degradation rate and application of the feed, and the silage is prepared from pennisetum purpureum, sugarcane tail leaves, corn straw and cassava branches according to the mass ratio of 4: 3: 2: 1. According to the silage, in the silage process, a lactobacillus casei R7-6 strain is added according to the inoculum size of 0.1%, and cellulase is added according to the inoculum size of 0.08%; the preservation number of the lactobacillus casei (Lactobacillus casei) R7-6 is CCTCC (China Center For Type Culture Collection) NO: M2018435. According to the invention, when several different coarse fodders are used as substrates, how to carry out ensiling treatment is researched, the degradation rate of the fodders in the cattle stomach and the cattle rumen can be effectively improved, the effective utilization rate of the coarse fodders is improved, the weight of beef cattle is also increa
