B The proportion of myofiber type composition in 3-week-old lambs. C Relative mRNA content of MyHC I, MyHC IIa, MyHC IIb and MyHC IIx in 3-week-old lambs. D Protein abundance of MyHC I and MyHC IIx in 3-week-old lambs. E Representative images on muscle fiber type composition of sheep at harvest. F The proportion of myofiber type composition of sheep at harvest. G Relative mRNA content of MyHC I, MyHC IIa, MyHC IIb and MyHC IIx of sheep at harvest. H Protein abundance of MyHC I and MyHC IIx of sheep at harvest. Data were shown as mean ± SEM; n = 8 in each group, *P < 0.05, **P < 0.01
