Abstract
As silage is one of the most important feed sources for dairy cattle it is recommended for farmers to preserve silage by fermentation. Interaction of the five strains of Lactobacillus genera [Lactobacillus buchneri A KKP 2047 p (LB), L. reuteri M KKP 2048 p (LR), L. plantarum K KKP 593 p (LPk), L. plantarum S KKP 2021 p (LPs), L. fermentum N KKP 2020 p (LF)] has been shown aiming to increase the safety of corn grain silage fodder. Experiments were conducted in polyethylene microsilos for 48 days and on production scale in an experimental farm for 3 years. Synergistic activity of the studied bacterial strains in terms of reducing aflatoxin B(1) and ochratoxin A levels was clear in these experimental variants wherein to the inoculants of the LB + LR strains subsequent bacterial strains LPk, LPs and LF were sequentially added. Silages inoculated with five bacterial strains were free from pathogens and showed the lowest yeast and mold count values among all experimental variants. As a result of employing the preparation starter culture for ensiling corn grain there were obtained silages characterized by high stability, microbiological and chemical purity, thus safe in feeding livestock.
