Dynamic changes in butyrate-producing bacterial communities during alfalfa ensiling and their potential metabolic functional profiles

Key Points

• The research investigates how butyrate-producing bacterial communities change during alfalfa ensiling and their metabolic functions.
• Analyzed changes in bacterial communities during alfalfa ensiling.
• Measured levels of butyric acid and acetic acid.
• Examined the influence of physicochemical factors on bacterial dynamics.
• Butyrate-producing bacterial communities significantly change during ensiling.
• Butyric acid and acetic acid are key factors affecting these changes.
• Both but and buk pathways are involved in the dynamics of these bacteria.
