1.对早期耻骨坐骨股内侧肌(PIF肌)、晚期耻骨坐骨股内侧肌(ITL肌)、髋臼后外侧肌(ITL肌)、成熟肌进行了研究。这两块肌肉含有不同群体的组织化学纤维类型。2.肌肉的轮廓测量显示出相对于体重的双时相异速生长。在生长早期(至孵化后15周)，肌肉的长度、宽度和深度都有所增加，而在生长后期(15~35周)，肌肉的生长主要是深度的显著增加，其次是宽度的增加。3.I型纤维，主要见于PIF肌，其成熟时间早于ITL肌的II型纤维。4.根据这些结果，对鸡骨骼肌生长的详细过程进行了讨论。
1. Early, M. pubo-ischio-femoralis pars medialis (PIF muscle) and late, M. iliotibialis lateralis pars postacetabularis (ITL muscle), maturing muscles were studied. These two muscles contained different populations of histochemical fibre types. 2. The profile measurements of the muscles showed diphasic allometric growth relative to the weights. In the early stage of growth (up to 15 weeks after hatching), the muscle length, width and depth all increased, while in the later stage (from 15 to 35 weeks) muscle growth resulted mainly from the marked increase in the depth and to a lesser degree, from an increase in the width. 3. Type I fibres, observed predominantly in PIF muscle matured earlier than the Type II fibres of ITL muscle. 4. From these results, the detailed process of skeletal muscle growth in the chicken was discussed.
