Abstract
Animal welfare has become a prominent concern around the world so that the laws and guidelines of animal welfare are being strengthened in many countries including the EU. In Korea, it is required to supplement animal welfare standards because social awareness of animal welfare has changed. This study was conducted to compare broiler welfare certification standards and improve the quality of practice. We found that broiler welfare certification standards differ among countries according to environmental and managemental differences. Standards for stocking density and perch which is considered more important for poultry welfare are similar, but there is a little difference in feed, water, litter and lighting. Therefore, we assumed that theses are able to revise standards taking into account the environment and suggested that the broiler welfare certification standard will serve as a more useful criterion if breeding conditions in Korea are considered.
