Summary

In a research project at HBLFA Raumberg-Gumpenstein 6 organic dairy farms are accompanied by converting to the „Low-Input“ seasonal grass-based system in the mountainous regions of Austria. After the first trial year (October 1st, 2004 – Septem-ber 30th, 2005), a pasture grass proportion of 36-60% in the total feeding ration per year could be determined, depending on each farm. Some farms completely dis-pensed with concentrate during the grazing period. Regarding the milk contents, a decreasing fat and protein percentage as well as an increasing urea content during the grazing period was observed. The project farms reached an average value of 0.26 cent of payments free of direct charge per kg milk. This value is a little bit higher than the Austrian average. In the future, the plant stock development on pastures should be observed in more detail and potential changes should be documented. Additionally, the nitrogen flows will be recorded.
