During the grazing period summer/autumn 2009 different pasture and biotope growth of sheep pasture located in low mountain range were characterized concerning their botanical composition. Furthermore using a difference cut before and after grazing dry matter intake of ewes as well as crude nutrient contents, metabolisable energy (ME), utilizable protein (uP) and mineral contents of pasture and biotope growth were determined. Biotope growth offered a more distinct diversity of plant species particularly in herbage compared with the pasture growth samples. However the former mentioned showed higher average values of crude fibre (300 vs. 267 g/kg DM) as well as a lower average ME concentration of 8.5 MJ/kg DM in comparison with 9.5 MJ/kg DM in pasture samples. The total range of ME and uP contents amounted to 8.1-9.6 MJ ME/kg DM, 100-122 g nXP/kg DM, respectively. A well-directed selection of sheep for plant material high in protein and energy, but low in fibre was observed. Dry matter intake of ewes ranged between 1.9 and 2.9 kg per animal and day. The feeding value of pasture and biotope growth meet the energy and protein requirement of ewes during maintenance and early gestation as well as during late lactation. In contrast supply recommendations for the performing stages of late gestation and early lactation were fulfilled only partial in pasture growth and at no time in biotope growth.
