Interannual and monthly variations of herbage production and nutritive value regarding the needs and welfare of grazing ruminants were evaluated in three grasslands located at different altitudes in northern Greece. The sub-alpine grassland was the most productive, with the highest mean annual CP content. Herbage Ca content was sufficient for the animals’ needs, while protein and phosphorus supplementation should be provided in order to cover their requirements and reach high levels of welfare.
