Based the investigation of the quality of roughage (alfalfa and red clover hay, natural meadows and maize silage) the following can be concluded: Quality of alfalfa hay was very good with protein content of 16.35%, which made it I category (Bassara method) to class II (method according to Barnes et al.). Red clover hay was of poorer quality – classes II and III with protein content of 12.65%. Meadow hay was of lowest quality – classes III and IV with protein content of 8.73%. High Ca content and unfavourable Ca: P ratio, were determined in leguminous hay, slightly better in meadow hay. Maize silage was extremely poor in proteins (5.84%), with high share of NFE and low byt fevourably Ca: P ratio (0.4: 0.2%). All roughages were with high share of crude fibre. Almost all maize silages were given high scores, i.e. first class according to DLG method. General conclusion would be that investigated roughages in said regions are of low quality, especially poor in crude protein content (except alfalfa hay), with high share of fibre and this represent limiting factor for more economically efficient production of milk and meat.
