Resumo(s)
The aim of this study was to evaluate the effect of two grazing regimes: the usual for the area
and late spring grazing, and three rates of N fertilisation, on dry-matter (DM) yields and nutritive
value in three mountain meadows (Anthemido-Cynosuretum cristati, Gaudinio-Agrostietum
cristati and Bromo-Cynosuretum cristati). The results showed that the lowest DM yield was
obtained on Bromo-Cynosuretum cristati meadow. Dry matter yields increased significantly with
N fertilisation in all meadows, independent of grazing regimes. The highest nutritive values occurred
at the beginning of spring, and decreased during the year as a result of maturation. This
effect was favoured by N fertilisation and it was independent of grazing regimes. Nutritive values
were sufficient to meet the daily requirements of beef cattle during the study.
