The effects of use of silage made from 4 maize hybrids (A, B, C, and D) of different dry matter digestibility (DM) on production performance of fattening cattle were investigated. Trial was carried plan on 60 male cattle of Holstein-Friesian Black and White breed, divided into 4 groups of 15 heads of each. Nutrition trial lasted 84 days. DM digestibility of maize hybrids used in this nutrition trial established in vitro was 58.38; 67.57; 60.74 and 61.91%, realized average daily gains of cattle were 813; 884; 816 and 836 grams and established differences were significant. Silage digestivility established by indirect method with Cr2O3 was 65.64; 76.10;70.90 and 72.78% and differences were also significant. Differences in in vitro digestibility of dry matter hybrids were in the amount of 9.2 percent points (67.57:58.38%), resulted in greater body mass of young cattle in average by 6.73 kg per head, i.e. higher daily gain of young cattle by 71 grams or 8.7%. Results of these researches indicated that dry matter digestibility of maize hybrids is extremely significant parameter of nutritive value.
