Note. Values in a line without a common lowercase mean that the relative quantities of the CAPN2 gene differ greatly significantly at the same age (P <0.05). Expression data were based on the mountainous black-bone chicken (MB). For each growth point, we used the Ct value of the liver as the control to calculate the expression values of the CAPN2 mRNA in other tissues.
