Roughage produced on crop fields is basic roughage in cattle's nutrition. If we do not have enough grassland, than we have to find alternatives in the vegetation period which are able to give cheap and natural roughage. Nowadays semi-intensive milk and beef production, as well as heifer rearing on the small or medium size farms, there is a demand for green fodder based diet during the vegetation period instead of monodietical or grass feeding. To achieve a more efficient system of green feeding it is necessary to introduce new species in ruminant nutrition as green fodder, which nutritional value has not been exactly evaluated yet. The objective of this paper compare to different green roughage mixtures could be used in the green feeding system. The next mixtures were examined: triticale & vetch ( Vicia pannonica), winter barley (1-lordeum vulgare)& vetch. The yield and nutrition content were determined for the whole mixtures and for each mixture component. There was significant difference among the roughage mixtures. Triticale mixed with pannon vetch (TR&PV) gave significantly higher yield (36.6 t/ha) than the two mixtures with winter barleys (29.7 t/ha and 31,4 tlha). The crude protein contents was the lowest in case of TR&PV (168 g/kg DM), the highest crude protein was found in case of barley mixed with pannon vetch (182 g/kg DM). The nutritional value found in case of pannon vetch with barley and pannon vetch with triticale highly differs from those of other green fodders mentioned by Schmidt et al (2000).
