%X The hams and shoulders of 315 pig carcases, ranging in weight from 90 to 174 lb, were visually appraised by four judges. The carcases were then jointed and the hams, middles and shoulders were weighed. There was no significant correlation between the visual appraisal scores and the weights of the joints expressed as a percentage of total carcase weight. Nor was there a significant correlation between the marks gained by the carcases on the basis of their body lengths and the weights of the middles expressed as a percentage of carcase weight. The economic advantage of a pig carcase with heavy hams and light shoulders is small, and it is suggested that there is no merit in continuing to appraise shoulders and hams visually when judging pig carcases. Where appraisal of these joints is required it is better to consider their weights in relation to total carcase weight.
