摘要

The effects of adding novel blends of homofermentative lactic acid bacteria (LAB) strain Entrococcus faecium, Lactococcus lactis, Lactobacillus plantarum; homo- and hetero-fermentative LAB strains Lactobacillus plantarum, Entrococcus faecium and L. buchneu homofermentative LAB strains plus sodium benzoate; homofermentative LAB strains plus Xylanase and homofermentative LAB strains plus Xylanase and plus sodium nitrate on the fermentation and aerobic stability of legume-grass mixture (Trifolium pratense L. and Lolim perenne L.) silages were studied under laboratory conditions. The second cut [265 g kg~(-1) dry matter (DM)] of a mixture of red clover and perennial ryegrass stand was harvested with standard field equipment. After the inoculants were added, the chopped forages were ensiled in anaerobic micro-silos and compared with the control silage prepared without an inoculant. The silages were opened after 90 days of ensilage and their chemical composition and aerobic stability were measured. Overall, microbial inoculants generally had a positive effect on grass-legume silage characteristics in terms of lower pH, ammonia-N concentrations, reduced DM losses and populations of yeasts and mould compared with control silages. Homofermentative LAB in combination with L. buchneri or sodium benzoate shifted fermentation towards acetate and had a great effect on the aerobic stability of slightly wilted red clover-ryegrass silages.
