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 less stable at aerobic exposure than silage without additives. When forage contained litle dry matter, homofermentative lactic acid bacteria had a favourable effect on aerobic stability and quality of grass silage. Inoculants of homofermentative lactic acid bacteria applied at ensiling of maize, sorghum and cereals also 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. Added strains of propionic acid bacteria have no effect on the ensiling fermentation of plants which are inherently unstable at aerobic exposure.
