[The role of behavioral science in animal welfare in teaching and practical application].

This paper gives an introduction on the importance of ethology as a basis for the ethical animal welfare. The last edition of the Animal Welfare Act of the Federal Republic of Germany is based on the ethological principle which includes, that the animal must be free to satisfy its needs and preserve itself from damage by using of adequate behavioural patterns. With the help of observing animal behaviour the veterinarian can remark faults in the animal management before pain, suffering or injuries set it. So the importance of the ethology in the system of veterinary education is clear. Pertinent information shall promote the dialogue between scientists working in the field of animal behaviour and people engaged in animal welfare.
