We studied the nutritive value and production efficiency of feed rations on the basis of maize silage with low (17.4%) and higher (28.52%) content of dry matter, fed together with lucerne silage, in feeding and balance experiments. We studied digestibility, nutritive value and production efficiency of roughage alone, and with the additive of feed mixture as well. Digestibility of nutrients in feed mixtures on the basis of maize silage with higher content of dry matter was higher than the digestibility of nutrients in feed rations with maize silage with low content of dry matter. The addition of feed mixture to the basic feed rations of roughage increased the digestibility of dry matter, crude protein, nitrogen-free extract and organic matter with the decrease of digestibility of fibre and fat. Young bulls fed the maize silage with higher content of dry matter and lucerne silage achieved average daily live weight gains 736 g, and 1146 g with the additive 2.65 kg feed mixture. In groups of young bulls fed analogical feed rations but with maize silage with lower content of dry matter were average daily live weight gains hihgly significantly lower (P0.01), by 349 g without feed mixture, and by 184 g with the addition of feed mixture
