Extract

Samples of the longissimus dorsi muscle were removed by biopsy from 4 pigs at intervals during the period from weaning to 125 lb. live-weight. In parallel studies involving 127 pigs attempts were made to relate mean fibre diameter to indexes of lean meat content of a range of bacon pig carcasses but only poor correlations were obtained. It was concluded that fundamental knowledge of the structure of the longissimus dorsi is not yet sufficiently advanced to allow accurate predictions of this type to be made.
