In the conditions of the Republic of Belarus there were analyzed the results on the determination of losses at the siloing of annual leguminous and cereal crops in different ratios. Raw material for siloing was grown on sod-podzolic light loamy soil, developing on light sandy loam, underlying from 30-50 cm of depth with free open-textured sand. It was established that with increasing of leguminous share there was lowering of dry matter content and increase of its losses. Dry matter losses also depended on raw material composition and varied from 4,4-6,3% at siloing of maize (Zea mays) and lupine (Lupinus angustifolius) up to 10,7-16,3% - at siloing of barley (Hordeum vulgare) and lupine (Lupinus angustifolius). Losses of feed units also increased with the increasing of leguminous share and varied from 10,4-18,2% (when specific weight of leguminous crops in green material was 25%) to 13,8-24,4% (specific weight was 75%). Dry matter, crude protein, fodder units and exchange energy output of artificially mixed annual forage crops and its losses at siloing were presented.
