Simplified detailed dissections were carried out in two sets of pig carcasses (120 gilts, 120 barrows). The results were used to establish a regression equation for the apparatus HGP. The lean meat content in gilts (Yp) and barrows (Yv) can be predicted using the following equations: Yp=60.76553-0.78012*S+0.11894*M (r=0.83; se=2.20); Yv=59.07731-0.75232*S+0.13500*M (r=0.82; se=2.20). To increase the accuracy of the prediction formulae carcass weight was included into the calculation. The prediction accuracy parameters r and se did not practically change. It is therefore concluded that the inclusion of carcass weight in the prediction formulae does not improve the prediction accuracy.
