While the muscle lengths increased significantly (P less than 0.001) with age, non-significant sex influences (P greater than 0.05) were obtained except for M. gastrocnemius and M. infraspinatus. The rate of longitudinal growth in muscles was greatest between the birth and 112 days of age. The ratio of linear equivalence (cubic root) of the muscle weights to muscle lengths indicated the proportionate increase in transverse growth relative to longitudinal growth. Generally, these ratios were higher in the earlier than in the later phase of growth and stabilized between 112 and 448 days post natal. Linear modelling of the growth gave highest values for male and lowest values for castrated animals. Muscle length growth was more closely related to body weight than to chronological age.
