The effects of lactic acid bacteria inoculation on the fermentation quality and aerobic stability of king grass silage

Abstract

Abstract: The effects of moisture contents (high, moderate and low) and lactic acid bacteria inoculation (LA, LB and LA+LB) on the fermentation quality and aerobic stability of king grass silage were investigated. All the silages were well preserved. The fermentation quality of king grass silages with moderate moisture content were better than those with high and low moisture content. LA inoculation did not significantly influence the fermentation quality of king grass silage, but the fermentation quality of king grass silages with high and moderate moisture contents was improved. LB or LA+LB inoculation increased the pH value (P<0.05) and acetic acid content, but decreased lactic acid content, the rates of lactic acid to acetic acid and lactic acid to total acid (P<0.01). When the silages of king grass were exposed to the air, the aerobic stability of LB and LA+LB inoculated silage were best.
