摘要: Abstract 1. Histochemical (fibre type distribution and areas) biochemical (myosin isoforms) characteristics of three muscles, M. anterior latissimus dorsi, pectoralis major sartorius, were compared among male chickens two lines at 11 55 weeks age. 2. The derived from a divergent selection based on growth rate. Cockerels the Fast Growing Line (FGL) 2‐3 times heavier than those Slow line (SGL) when old 1–7 latter age was chosen as representative adult stage 11‐week because, this time, FGL cocks weighed much SGL cockerels weeks. 3. At both ages, showed similar fibre distributions, but total number in ALD muscle, size (cross‐sectional fibres each muscle higher with (14–6% 33% more respectively favour birds). 4. displayed myosin ...
