摘要	Sweet sorghum is a variety of promising energy crops with high sugar content, rapid growth rate, and strong resistance to saline-alkaline soils. Appropriate storage is highly required to utilize this feedstock for continuous bioenergy production, particularly harvested in a seasonal manner in China. In this study, the addition of rumen fluid was introduced to sweet sorghum for better ensiling quality during long-term (30 to 60 days) storage. A systematic investigation was made on the ensiling profile, including the organic components, fermentation quality, and enzymatic hydrolysis of sweet sorghum silage. Furthermore, an experimental analysis was performed on the dynamic process of microbial community during ensiling. The sweet sorghum was ensiled at 5 different dosages of rumen fluid: CK, silage without the addition of additive; R1, silage with rumen fluid at 1 mL/100 g, R3 at 3 mL/100 g, R5, 5 mL/100 g, R7 at 7 mL/100 g substrate. The results showed that the contents of dry matter (DM), water-soluble carbohydrates (WSC), crude protein (CP), and ammonia nitrogen (AN) decreased significantly, as both ensiling time and dosage increased in four treatments with the addition of rumen fluid, compared with the CK silages without rumen fluid. The increased rumen fluid and prolonged ensiling contributed to reducing the content of acid detergent fiber (ADF), neutral detergent fiber (NDF), cellulose, and hemicellulose, while elevating the abundance of beneficial Lactobacillus in silages. Lignin in silages at ensiled for 60 days was effectively removed when the maximum dosage of rumen fluid was up to 7 g/100 g. There was a significant decrease in the contents of lactic acid and acetic acid, as well as the pH values in five treatments (CK, R1, R3, R5, R7), with the extension of the ensiling period (P © 2021, Editorial Department of the Transactions of the Chinese Society of Agricultural Engineering.
