2. Literature Review and Theoretical Framework

2.1 Animal Welfare Science and Industry Standards

Animal welfare science has evolved significantly over the past several decades, establishing evidence-based frameworks for assessing and improving the treatment of animals in agricultural production systems. The Five Freedoms framework, originally developed by the UK Farm Animal Welfare Council, provides fundamental principles that guide contemporary animal welfare assessment: freedom from hunger and thirst, freedom from discomfort, freedom from pain and disease, freedom to express normal behavior, and freedom from fear and distress (Webster, 2016).

The application of scientific animal welfare principles to commercial food production requires comprehensive understanding of species-specific behavioral needs, physiological requirements, and environmental factors that influence animal well-being. Contemporary research in animal welfare science has demonstrated clear connections between improved welfare conditions and enhanced product quality, reduced mortality rates, and improved production efficiency (Dawkins, 2017). These findings provide scientific justification for corporate investment in animal welfare improvements beyond ethical considerations alone.

2.2 Corporate Responsibility and Supply Chain Governance

The theoretical foundation for corporate animal welfare initiatives rests upon stakeholder theory and the concept of extended producer responsibility, which recognizes that companies bear ethical obligations for practices throughout their supply chains, not merely their direct operations (Freeman et al., 2020). This framework requires companies like Costco to develop comprehensive governance systems that ensure animal welfare standards are consistently applied across diverse suppliers and geographical regions.

Supply chain governance for animal welfare presents unique challenges related to monitoring complex production systems, verifying compliance with welfare standards, and supporting supplier capacity building for improved practices. Contemporary research indicates that effective animal welfare governance requires combination of contractual requirements, third-party verification, supplier education, and economic incentives that align welfare improvements with business objectives (Tonsor & Wolf, 2011).
