[Animal rights and animal health on ecological farms].

Intensive animal husbandry is criticized in relation to the fulfillment of the animals needs. The guidelines of the organizations of organic agriculture offer the opportunity for better animal welfare. In this paper an overview is given concerning animal health and welfare on organic farms with dairy cows, fattening pigs and laying hens. On organic farms housing systems with the potential for a better animal welfare dominate. In field studies using scoring systems (animal welfare index) organic farms reach more points than conventional ones. However, animal health on average is not much better on organic farms. The health problems discussed in the paper are mainly caused by management problems. Therefore, improvements are possible.
