The goal of our work was to determine the influence of chemical preservation on fermentation indicators, nutritional value and aerobic stability of silage of maize grain with about 66.5% of the dry matter. The coarsely ground maize grain was ensiled in glass laboratory vessels. After the fermentation the vessels were opened, one part of the mass was analyzed and one part was stored in special boxes isolated from the surrounding environment by a 10 cm layer of polystyrene. After 24, 48, 72 and 96 hours the silages were analyzed. The temperatures were measured continuously also after 168 hours, i.e. the seventh day after the start of ensilaging. The control silage of wet maize grain without preservative was stable for about 48 hours, then it started decaying quickly (the temperature rose from 19 deg C to 30.5 deg C, pH from 5.0 to 5.9, acidity of water extract dropped from 774 to 471 g/kg). The silages preserved by chemical preparations in doses of 3 and 6 litres per ton of wet grain were stable in air for the whole 7 days of observation.
