Summary

The pro-q-project is an udder health programme especially for organic farmers under Swiss conditions. The aim is to minimize the use of s antibiotics and to assure a good udder health state on the farms. At the end of the third project year of 100 project farms 16 participate for more than two years. The udder health situation of these 16 farms improved moderately in the second project year (37% of the cows with a so-matic cell count > 100’000/ml) compared to the year before project start (40% of the cows with a somatic cell count > 100’000/ml). Furthermore, a nearly linear increase of the arithmetic mean of herd lactation number (3.27 year before project start, 3.33 first project year, 3.44 second project year, resp.) could be found. The number of antibiotic treatments per cow and year decreased from 0.37 in the year before project start to 0.24 in the second project year.
