Abstract: In order to compare and analyze the effects of different starter cultures on the silage fermentation quality of sugarcane tips, three starter cultures, namely compound microbial bacterial (Aspergillus niger:lactobacillus:Candida utilis was 2:23), silage starter cultures and ruminant polypeptide, were used to silage ferment the sugarcane tips. The results showed that after the silage fermentation for 45 days, the sensory quality of silage products of sugarcane tips in the groups treated with three starter cultures reached the optimal level. There was no significant difference in conventional nutrient content and silage quality among the groups treated with three starter cultures, but the effect of the compound microbial bacterial in fiber degradation was better. Therefore, the compound microbial bacterial should be selected in priority for the silage fermentation of sugarcane tips in production, and the recommended dosage was 250 g·t^-1.
