Abstract

Single-frequency bioelectrical impedance (resistance and reactance) was measured from one hundred and thirteen chilled lamb carcasses. The carcasses were later cut into the DEVCo cuts and every cut was weighed. These cuts were: Legs, Loin, Rack, Shoulders, Shanks, Flap, Breast and Neck. The bioelectrical impedance data, together with carcass weight and temperature, were used to predict the weights of each of the DEVCo cuts. The best prediction was for the DEVCo Legs cut (adjR2 = 0.945), and the worst prediction was for the DEVCo Neck cut (adjR2 = 0.369). The data analysis revealed carcass weight to be the single best predictor of DEVCo cut weights, and that adding the bioelectrical impedance data did not improve prediction significantly.
