The Potential Effects on Microbiota and Silage Fermentation of Alfalfa Under Salt Stress.

ABSTRACT: This study investigated the fermentation quality of alfalfa grown in different salt stress regions in China. Following the production of silage from the natural fermentation of alfalfa, the interplay between the chemical composition, fermentation characteristics, and microbiome was examined to understand the influence of these factors on the fermentation quality of silage. The alfalfa was cultivated under salt stress with the following: (a) soil content of <1%0 (CK); (b) 1-2%0 (LS); (c) 2-3%0 (MS); (d) 3-4%0 (HS). The pH of the silage was high (4.9-5.3), and lactic acid content was high (26.3-51.0 g/kg DM). As the salt stress increases, the NA⁺ of the silages was higher (2.2-5.4 g/kg DM). The bacterial alpha diversities of the alfalfa silages were distinct. There was a predomina
