In this study four maize silages from different hybrids were evaluated in terms of chemical composition, dry matter yield (DMY), metabolizable energy (ME) and in vitro dry matter digestibility (IVDMD). Crude fibre (CF) of the silages ranged from 23.0 to 25.4%. There were no differences between silages in terms of dry matter (DM), crude protein (CP) and ether extract (EE). Dry matter yield (DMY) ranged from 16425 to 19577 kg/ha-1. It was concluded that there were significant differences in crude fibre, ash, DMY, IVDMD and ME between four the hybrids. The rank order in terms of metabolizable energy yield (MEY) or digestible dry matter yield (DDMY) was the same and as follows: Otello> Golden>Broskov>Maverik. Otello had a high index value. Therefore it can be recommended for silage production. However, feeding trials with ruminants are required to see how these differences can affect animal performance such as milk or meat production.
