## Abstract

Pork carcass fabrication is a central determinant of value realization within packing and processing systems, translating biological variation in carcass weight and composition into economic outcomes under dynamic market conditions. The objective of this review is to synthesize current knowledge on the economic drivers of pork carcass fabrication, with a specific focus on the interactions among carcass characteristics, fabrication strategies, and value realization. Regional differences in cutting specifications and market orientation are discussed as key factors shaping primal yields, market allocation, and value distribution across domestic and export channels. The economic contributions of primals, subprimals, trim, fat, and by-products are examined in the context of wholesale pricing signals, carcass merit programs, and packer-specific specifications that link production decisions with downstream processing requirements. Fabrication strategies, including depth of fabrication and primal-specific cutting decisions, are evaluated with respect to yield optimization, labor and packaging costs, and market flexibility. The influence of carcass weight and composition on fabrication efficiency, trim generation, and fixed cost allocation is highlighted, illustrating trade-offs between biological performance and processing constraints. Technological advancements, including instrument grading, automation, and data integration, are reviewed for their role in improving yield prediction, carcass sorting, and operational consistency, while emerging tools such as predictive modeling are identified as promising approaches for managing variability and economic risk. Price volatility, biological variability, and supply chain disruptions are identified as persistent challenges to fabrication economics, underscoring the need for resilient and adaptable processing systems. Beyond economic performance, fabrication decisions are discussed in relation to labor welfare and sustainability outcomes. Collectively, this review emphasizes that optimal pork carcass fabrication is achieved through the strategic integration of biological inputs, economic signals, and operational capabilities. Improved data transparency and collaboration between industry professionals are essential to develop integrated biological-economic frameworks that enhance value realization and long-term sustainability across the pork supply chain.

Pork carcass fabrication decisions quietly shape profitability across the entire supply chain, from primal yields to labor efficiency and market access. This review explores how carcass characteristics, fabrication strategies, and emerging technologies interact with market dynamics to influence economic outcomes in the modern pork industry.
