title: Welfare assessment in porcine biomedical research - suggestion for an operational tool.
abstract: In recent years, increasing interest in using the pig (Sus scrofa) for biomedical research has become evident. Today, the pig is considered an advantageous alternative animal model for various human diseases and conditions. However, even though a considerable amount of biomedical research has been done on pigs, hardly any studies include systematic welfare assessment. Still, it is essential to assess welfare of laboratory pigs, both domestic pig breeds and smaller purpose-bred breeds, as (1) scientific obligations entail responsibility to ensure and document a fair welfare standard for animals used for experimental purposes; and (2) the scientific outcome can be dependent upon the welfare state of the animals. In order to be able to quantify and control laboratory pig welfare, a practical tool is needed. The purpose of the present paper is to provide an overview of the current status of the extent of welfare assessment in pigs used in biomedical research and to suggest a welfare assessment standard for research facilities based on an exposition of ethological considerations relevant for the welfare of pigs in biomedical research. The tools for porcine welfare assessment presented suggest a method for monitoring the welfare status of individual laboratory pigs, intended to relieve the practical scoring of the welfare of individual pigs as well as the interpretation of the findings.
