Y. Cherel et al., COMPARISON OF POSTNATAL-DEVELOPMENT OF ANTERIOR LATISSIMUS-DORSI (ALD) MUSCLE IN HEAVY-WEIGHT AND LIGHT-WEIGHT STRAINS OF TURKEY (MELEAGRIS-GALLOPAVO), Growth, development and aging, 58(3), 1994, pp. 157-165
ALD muscle development was studied from day 2 to week 15 in males of t
wo turkey strains. At 15 weeks, the heavy-weight (HW) strain weighed 2
.2 times as much as the light-weight strain (LW). Morphometric and imm
unocytochemical analysis showed the presence of small fibers in KW ALD
muscle which simultaneously accumulated ventricular and embryonic fas
t myosin heavy chain isoforms. The appearance of these nascent myofibe
rs suggests that hyperplasia contributes to the growth of HW ALD muscl
e.
