Jujube powder supplementation optimized high-moisture alfalfa silage through regulating microbial community.

ABSTRACT: In order to improve the quality of fresh alfalfa silage, we investigated the effects of jujube powder (JP) addition on the ensiling process of high-moisture alfalfa (75% moisture content) over fermented periods of 1, 5, 15, 30, 45 and 60 days. We evaluated chemical composition, bacterial and fungal community dynamics and diversity, co-occurrence networks, microbial functionality and the ability to restrict pathogenic contamination. Results showed that JP addition optimized key fermentation parameters (pH, lactic acid, volatile fatty acids, and NH₃-N) in high-moisture alfalfa, achieving levels comparable to those of traditional wilted alfalfa qualified silage. JP also increased the abundance of beneficial bacteria while suppressing undesirable organisms. A dominant lactic acid ba
