The planned implementation of a self-evaluation regarding animal welfare using animal-based indicators by BIO AUSTRIA served as the starting point for the present thesis. The aim of the study was to determine the members opinions regarding importance and use of animal-based indicators as well as the self-evaluation using animal-based indicators. Additionally it was the aim to obtain the farmers views about the incorporation of animal-welfare assessment in the annual inspection of organic farms. Therefore, questionnaires were handed out during the BIO AUSTRIA Farmers days 2015 and an online survey was conducted which was sent to BIO AUSTRIA members. Using these data, correlations between various farm characteristics and opinions regarding animal-based indicators, self-evaluation and animal welfare assessments were examined in order to find possible reasons for barriers. Furthermore, three interviews with experts, who have already implemented animal-based indicators in practice, were conducted. One other interview conducted with an Austrian organic inspection body brought insights to the possible implementation of animal-welfare on-farm assessments. The use of animal-based indicators are part of the farmers daily routine and the indicators presented in the questionnaire were rated as important. Pronounced differences were found regarding the feasibility of influencing different indicators. The implementation of animal-based indicators in the annual inspections of organic farms was supported to a lesser extent than self-evaluation. The expert interviews underlined the importance of a good communication process with farmers and their integration when decisions are necessary. The interview with an Austrian organic inspection body showed, that implementation of animal-based indicators in organic inspection would be possible; in fact, it is already applied in a small number of Austrian farms which are members of German organic farming associations.
