摘要： Fungi play a critical role in silage and rumen fluid, both of which share similar ecosystems. This study is designed to supplement sweet sorghum ensiling with the rumen fluid from beef heifers and evaluate the effect on fungal diversity dynamics and silage quality by high-throughput sequencing and chemical methods. Simultaneously, this study investigated the correlation between fungal communities and chemical compositions of silages. The results suggested that the addition of rumen fluid significantly affected the richness and diversity of fungi in silage. Alpha diversity of total fungi and the relative abundance of Pichia increased, while Schizophyllum and Penicillium decreased, following the supplementation of rumen fluid during 60 days ensiling. In addition, the silage quality was positively correlated with Pichia, but negatively correlated with Hannaella and Vishniacozyma. The findings reveal that the rumen fluid can improve the ensiling characteristics by effectively reducing the reproduction of adverse fungi. However, further research is required to verify the connection of specific pure fungal isolates with the fermentation performance of silage.
