Extract

Recent estimates of the genetic parameters of the traits used in the MLC Lean Index (Simm and Dingwall, 1989) have suggested that the rate of genetic progress in carcase quality could be improved by using alternative indexes (Pollott, 1994). This study was carried out to investigate the changes in a range of carcase components using these alternative selection indexes. Interest is particularly focused on changes in fat depots and bone weight under selection, as well as that of the primary trait of interest, lean weight.
