References and efficiencies of the primer sequences that were used for qPCR.

The three muscles were: biceps femoris (BF), longissimus dorsi (LD), and ventriculus sinister cordis (VSC).ND = not determined.aEfficiency = 10−1/(slope of standard curve). Efficiency was calculated by LightCycler software (ver 2.0, Roche Applied Science, Penzberg, Germany).本次涉及的三种肌肉分别为：股二头肌（biceps femoris, BF）、背最长肌（longissimus dorsi, LD）与左心室（ventriculus sinister cordis, VSC）。ND 代表未测定（not determined）。a 效率（Efficiency）= 10−1/(标准曲线斜率)。该效率值通过LightCycler软件（版本2.0，罗氏应用科学公司，德国彭茨贝格）计算得出。
