Effects of different lactic acid bacteria groups and fibrolytic enzymes as additives on silage quality: A meta-analysis

A database was developed from 97 articles and used to examine the effect of inoculant rate obligate homofermentative facultative heterofermentative lactic acid bacteria (OF-LAB) LAB (O-LAB) on silage quality using meta-analysis. This study also compared groups with or without fibrolytic enzyme legumes forages based-silage. Results regression equations showed that elevating levels OF-LAB linearly reduced pH increased (LA) during ensiling but had no aerobic stability. Conversely, O-LAB Compared control group, containing enzymes decreased by 12.15% LA neutral detergent fibre (NDF) 58.94% 12.23% respectively which is highest than other groups. In conclusion, although all types inoculants are effective improve quality, response plant materials varied.
