Abundance of transcripts encoded by genes associated with meat quality in chicken skeletal muscle as affected by delayed postmortem. Bars represent fold changes (mean± standard error of the mean) in expression of genes at 1.5 h or 6 h postmortem relative to the expression in the samples at 20 min postmortem. The genes of interest are insulin-like growth factor (IGF1), pyruvate dehydrogenase kinase, isozyme 4 (PDK4) and peroxisome proliferator-activated receptor delta (PPARD). TATA box-binding protein (TBP) was used as a reference gene in the 2^−ΔΔCt calculation. * p<0.05.
