To exploit and use kudzu and sugarcane top resource,and produce high quality silage,kudzu and sugarcane top were mixed by six ratios,namely 10∶0,9∶1,8∶2,7∶3,6∶4 and 0∶10,which were short for 100K,9K1S,8K2S,7K3S,6K4S and 100S,respectively.Each treatment had 5 replications and the mixed materials were ensiled for 50 days at normal temperature.Then nutritional indexes and fermentation quality indexes were measured.The results showed that with the increasing proportion of sugarcane top,pH value and content of dry matter and ammonia nitrogen decreased,contents of neutral detergent fiber,acid detergent fiber,hemicellulose,lactic acid,acetic acid and propionic acid increased and the quality of kudzu and sugarcane top mixed silage (except 100S) was becoming better.In general,mixed silage of 6K4S had relatively lower pH value and ammonia nitrogen content,and relatively higher contents of crude protein and lactic acid,indicating that mixing kudzu and sugarcane top by the ratio of 6:4,the quality of mixed silage was the best.
