Three extensive production processes with different ruminants were examined (sheep farming and lamb production, suckler cow farming and young cattle, ox fattening). All variants were evaluated with and without Alpung. Existing results from organic milk production were used as basic reference data, as it is the most intensive form of ruminant farming in extensive agriculture. A comparison with intensive livestock farming or arable farming was not carried out because these forms of farming cannot be implemented in mountain areas.
The alpine pasture period itself is largely uncontaminated by direct and indirect releases, and even the greenhouse gas pollution can be viewed as neutral in the long term. In all cases, alpine farming has a lower environmental impact. The largest influence on the results is the purchase of animals in specialized ox fattening and the lower production efficiency in lamb production. Suckler cow farming performs favorably.
Overall, the animals' earnings during the alpine pasture season are offset by virtually no emissions. Extensive use of alpine pastures is the best contribution to sustainability in keeping ruminants. Nevertheless, it is the art of agricultural management to organize the optimal use of resources for one's own location.
