Carcass Grading for Local Vietnamese Ban Pigs and its Potential for a Quality Feedback System in a Short Food Supply Chain

In-situ conservation of local pig breeds in Southeast Asia requires genetic improvement embedded in viable marketing concepts. Increasing demand offers marketing opportunities for indigenous Vietnamese Ban pork. This study sought to adjust estimation methods for grading light carcasses according to their leanness. Using data from the dissection of 45 carcasses, several models were fitted and evaluated. Although the predictive power of the equations was limited, Ban carcasses could be approximatively classified according to their lean content. Finally, a suggestion of how to include these measurements in a quality feedback system of a short food supply chain is made.
