Field experiments were conducted during a period of 1997 to 2001 on Stagnic Luvisol and Sod Podzolic soils. Binary seed mixtures were composed of forage legumes: Galega orientalis, Medicago varia, Trifolium pratense and grass species: Alopecurus pratensis, Dactylis glomerata, Festuca pratensis, Phleum pratense, Lolium perenne. Mixtures of legumes and grasses or in pure swards red clower, lucerne and fodder galega could be used as crops with potential for high crude protein content. Non-wilted red clover, fodder galega and timothy-red clover mixture have poor ensilability. Inoculant Feedtech TM Silage was not effective in controlling the butyric acid fermentation in the high moisture silage. Addition of inoculant had a positive effect on fermentation characteristics of wilted legume silage. Inoculation resulted in four times lower mould counts, and the counts of clostrida spores were two times lower in comparison with untreated silage. The use of inoculant in farm-scale experiment resulted in higher silage dry matter intake and higher milk yield. Cows offered inoculated produced, on average, 23.2 kg of FCM per day and it was by 1.2 kg higher than the milk yield produced by cows offered untreated silage.
