Studies were made in the years 1986-1992 in Jaworki (Small Pieniny Mts.). On four neighbouring pastures young cattle (heifers), Polish Red, were grazed. Two pastures were utilized by rotational system of paddock and the two a free grazing system. Within the frame of given system, pastures were differentiated by the cutting of the residual plants after grazing. The animals were grazed in non stop system and fed only with the green pasture forage. Plant and animal production were recorded and the botanical composition of sward. It was found that the paddock system of grazing improves the quantity and quality of yields. In comparison with the free grazing the differences amounted 0,8-1,2 t/ha DM. Cutting of residual plants caused decreased of plant biomass up to 1,3 t/ha and 0,9 t/ha DM on the pasture, with a free pasture system. However, this decrease has been compensated by the higher feeding value of fodder which at the beginning of studies was classified as good (the number of utilization value - 7,4) whereas at the end was evaluated as very good (respective number of utilization value - 8,2).
