Enhancing alfalfa and sorghum silage quality using agricultural wastes: fermentation dynamics, microbial communities, and functional insights.

At present, there are many researches on the nutritional quality and fermentation quality of forage silage by adding distillers' grain and fruit residue, but few researches on the succession and function prediction of microbiotic community.

Multi-omics analyses reveal new insights into nutritional quality changes of alfalfa leaves during the flowering period.

High-quality alfalfa is an indispensable resource for animal husbandry and sustainable development. Its nutritional quality changes dramatically during its life cycle and, at present, no molecular mechanisms for nutrient metabolic variation in alfalfa leaves at different growth stages have been clearly reported. We have used correlation and network analyses of the alfalfa leaf metabolome, proteome, and transcriptome to explore chlorophyll, flavonoid, and amino acid content at two development stages: budding stage (BS) and full-bloom stage (FBS).
