The aim of the project is to develop an animal-related indicator system for use in audits to assess the level of animal welfare on organic Peking duck farms with surveys in the barn and at the slaughterhouse and to test its practical suitability. This includes an extensive literature research to identify suitable animal-related indicators and the development of proposals for survey methods for the indicators to be collected at farm level and at the slaughterhouse with detailed descriptions and illustrations. The developed scoring schemes will be tested in a field study in practice farms and a slaughterhouse with regard to the criteria of validity, reliability and practicability. Based on the findings of the practical tests on the project farms and at the abattoir, the selection of indicators and method descriptions will be critically reviewed and modified if necessary. Training materials in the form of guidelines and survey cards will then be compiled for the inspectors and slaughterhouse employees.
