Considerable nutrient losses during silo storage are caused by aerobic decay as a result of yeasts and fungi
growth aŌer opening the pit. HeterofermentaƟve lactobacilli are natural antagonists to them. They are used
for the biological preparaƟons “Biotrof 600” and “Biotrof 700” for ensiling based on Lactobacillus plantarum
and Lactobacillus buchneri respecƟvely. The efficacy of ensiling plant material with these preparaƟons was as-
sessed in comparison to homofermentaƟve bacterial preparaƟons and chemical preservaƟves. AerobioƟc sta-
bility of the feed was also esƟmated as dependent on the inoculum. Laboratory, semi-industrial and industrial
trials were organized to assess the feed quality by the fermentaƟon products, nutrient losses and producƟve
effect of the experimental feeds on faƩening Black-and-White bull-calves. Nutrient losses during the preserva-
Ɵon period are higher in heterofermentaƟve working, and the green mass’ sugars to buffer raƟo being low (<
3.0), they do not provide the required feed pH. However, ensiling grasses with high sugars to buffer raƟo, the
studied preparaƟons provided the best aerobioƟc stability, with only 2 % nutrient losses in comparison to 5 %
in the homofermentaƟve-inoculated material. The producƟve effect of silage made with “Biotrof 700” was also
higher than that of the untreated fodder: the bull-calves daily weight gain was 13.7 % more in comparison to
the reference group.
Keywords: ensiling, aerobioƟc stability, nutrient losses, inoculum, heterofermentaƟve lactobacillus.
