Abstract

The effect of bacterial inoculants on aerobic stability of silage was studied on the basis of statistical processing of data from literature. When forage had higher content of dry matter aerobic stability of grass silage, inoculated with homofermentative lactic acid bacteria, was lower than in silage without additives. When forage had low dry matter content, homofermentative lactic acid bacteria had a favourable effect on aerobic stability and quality of grass silage. Inoculation of maize, sorghum and cereals improved the quality but impaired the aerobic stability of silages. An exception was inoculant of Lactobacillus plantarum and Enterococcus faecium that slightly improved aerobic stability of cereals silage. Heterofermentative lactic acid bacteria Lactobacillus buchneri improved the quality and aerobic stability of maize, sorghum and cereal silages and was unaffected in grass silage. Additives which contained propionic acid bacteria have no effect on the fermentation of plants which are inherently unstable at aerobic exposure.
