Abstract


Yield, botanic composition and chemical analyses of grazing herbage were observed in four localities with different altitude. The altitude was for first place at 600-650 m, second place at 700-750 m, third place at 700-800 m and the fourth place at 400- 700 m. Grazing herbage is the most natural and optimal feedstuff for all kinds and categories of cattle. Grazing should notably regulate the pasture composition, i.e. support dominance of soft stolonate strain of grasses and decrease occurence of weeds and less value strain of graminoids and herbs. Grazing was found to be 20- 30% less of species then in hewed herbage. Grazing in the earlier growth period supported the development of lower stolonate graminoids and Trifolium repens at the expense of high-grown graminoids and other herbs. Selective character of grazing was at the time the animals had at disposal larger area then forage usage. Part of herbage evaluation was also observation milk and meat quality on farms. Owing to grazing there were some changes in protein content and protein fraction. At the grazing the part of alfa-lacto-albumin has increased.
