	abstract = {The present New Zealand export lamb carcass classification  system places carcasses into groups differing on average in fat (and  meat) proportion (e.g. YM=20.6\% fat, PM=23.8\% fat, TM=27.0\% fat and  FM=28.2\% fat). There is, however, considerable overlap in fat  proportion between adjacent fatness classes. A comparison of the  present mainly visual assessment system (one grader) with one based  solely on measurement has shown that the objective systems investigated  to date do not bring any major improvements in terms of sorting  carcasses on the basis of composition. However, other advantages  associated with an objective system, including the ability to sort out  carcasses of any desired fatness range which may differ from current  specified class ranges, makes the introduction of an instrument  measurement based system extremely likely in the near future. As yet, a  satisfactory instrument for this purpose has not been identified.  },
