The results of the grouping were used to classify Farm Management Grades (A, B, C, D grade).<h4>Results</h4>The proportion of primal cuts in pigs, according to the new classification method, increased from group A to group D for shoulder blade, shoulder picnic, and ham, but decreased for loin and belly. In the regression analysis of the five primal cuts (shoulder blade, shoulder picnic, loin, belly, and ham) production (kg) for each group, all regression equations showed low errors (MAE<0.7), indicating that the Animal bioscienceNew management grading for pig farms: management grading system using pig carcass weight, back fat thickness and k-means algorithm.PMC117257512021RIS001Kim GLim YKim JChoi JfalseNew management grading for pig farms: management grading system using pig carcass weight, back fat thickness and k-means algorithm.<h4>Objective</h4>This study categorized farm management levels to improve the productivity and uniformity of pork from pigs shipped from farms.<h4>Methods</h4>A total of 48,298 pigs were grouped (A, B, C, D group) using the k-means algorithm, carcass weight and backfat thickness.
