The production yields of five primal cuts\n                    (shoulder blade, shoulder picnic, loin, belly, and ham) were quantified, with\n                    ham showing the highest yield and shoulder blade the lowest. Pearson correlation\n                    analysis revealed strong positive correlations (r &gt; 0.7) between carcass\n                    weight and each primal cut, with the shoulder blade showing the highest\n                    correlation. Backfat thickness exhibited only weak positive correlations with\n                    primal cuts. Simple linear regression models for each primal cut yielded\n                    coefficients of determination (R2) ranging from 0.71\n                    to 0.88, with shoulder blade showing the highest value. Multiple linear\n                    regression, using all five cuts as predictors for carcass weight, resulted in a\n                    high R2 of 0.98. Monthly analysis showed that\n                    carcass weight and primal cut yields were highest during winter months (December\n                    to February) and lowest in summer (June to August). An increase in temperature\n                    adversely affected pig production. Consequently, utilizing the non-destructive\n                    carcass analyzer for monthly evaluation of pig carcass characteristics is\n                    effective for predicting pork production in response to temperature\n
