The objective of the research project was to determine the influence of chemical (KemiSile 2000) and bilogical (Lactacel L) silage additives on the hygiene quality and nutritive value of maize silages treated with a mould inoculum of Penicillium verrucosum 410. The experiments were conducted on S.C. type Celux cultivar of maize (FAO 220) with a 34% dry matter count that was harvested in August 2002 and ensiled in 3 variants (each variant in 3 replications). Group 1 was a control and comprised silage without any additives, group 2 was ensiled with the addition of 0.25% KemiSile 2000, while group 3 was treated with 0.20% Lactacel L preparation. After 12 weeks of the silage process individual silages were subjected to chemical analyses, and the microbiological composition of silages was also determined. Similar analyses were repeated following a 7 day period of exposure to oxygen. The applied silage additives were not found to have a significant influence on the chemical composition of silages. Nevertheless, silages supplemented with KemiSile 2000 contained higher levels of water soluble sugars and smaller quantities of lactic acid. The applied silage additives reduced quantities of coli and Clostridium bacteria and improved the hygiene quality. After the exposure to oxygen, the quantities of yeasts and fungi increased and the pH value increased dramatically. The ensiling process caused significant changes in the fungal microflora of silages; the quantities of Penicillium verrucosum decreased considerably, while Penicillium roqueforti turned out to be the dominant species in the examined silages.
