Dynamic of nutrients quality characteristic of pasture in different altitude in South Bohemian region

Abstract

Yield, botanic composition and chemical analyses of grass and herbage were measured in seven localities with different altitudes between 450 and 900 metres above sea level. Grass and herbage are the most natural and optimal feedstuff for cattle. Grazing management should notably regulate the pasture composition, i.e. support dominance of soft stoloniserous strains of grasses and decrease occurrence of weed and less value strain of gramineous grasses. Grazing in the early growth period supported the development of lower stoloniserous grameous grasses and Trifolium repens. A part of the herbage evaluation was observation milk and meat quality on farms. Due to grazing there were some changes in protein content and protein fraction, although not statistically significant.
