Relative concentrations of the 2 electrophoretic fragments identified in Pectoralis major muscles of broiler chickens belonging to fast-growing (FG) and medium-growing (MG) genotypes at different ages through the western blot analysis and having a molecular weight of 72 kDa (A) and 125 kDa (B). The results are expressed as %, considering as 100% the intensity of the band respectively assigned to the 72 and 125 kDa fragment in MG broilers at d 7. Values are expressed as mean values (%) ± standard error of mean. Within each sampling time (7, 14, 21, 28, 35, and 42 d), the Mann–Whitney U test was used to assess the differences between FG and MG. * = P ≤ 0.05 and ** = P ≤ 0.01. Moreover, one-way ANOVA was used to assess the evolution of the 72 and 125 kDa electrophoretic fragments (A and B) in FG over their growth period. a-c = for FG, different superscript letters indicate significant differences over the growth period (P ≤ 0.05).
