Extract

A Quality characteristic of the bacon side is the fat to lean ratio of the rashers obtained from it. Although this measurement has received attention in carcass evaluation (Pearson, Bratzler, Hoefer, Price, Magee and Deans, 1956; Lucas and Mitchell, 1962; Jonsson, 1963), unlike many others its accuracy as a predictor of lean content of the carcass has not been established. On this basis it was considered worth while to undertake an analysis of the method.
