Abstract: This thesis is an investigation of the use of electronic probe technology (Viewtrak PG-207 optical probe) for predicting saleable meat yield (SMY) in lamb carcasses. 370 lambs were used in this study to compare probe versus carcass measures of backfat and longissimus muscle depth. Pearson correlation coefficients were determined to test probe accuracy versus actual carcass measures. Multiple regression analysis evaluated relationships among probe and carcass measures to SMY. ANOVA was used to determine significant predictors of saleable meat yield and develop prediction equations. Coefficients of determination (R2) for models with probe measurements on the hot carcass ranged from 0.014 to 0.284 (P ≤ 0.86) and 0.120 to 0.316 (P ≤ 0.50) on the chilled carcass. In this study, Viewtrak PG-207 optical probe measurements could not be used alone to accurately predict SMY in lamb carcasses.
