ABSTRACT The aim of this study was to investigate the effects of Myostatin (MSTN) and MyoGenin (MyoG) on goose skeletal muscle growth. In this study, MSTN and MyoG gene expression in breast and leg muscle of Zi and Rhine goose were detected by Real-time Polymerase Chain Reaction (PCR), and the correlations between genes expression levels and carcass traits were investigated. The results showed that the breast muscle weight and breast muscle percentage of Rhine goose were significantly higher than Zi goose (p<0.01). MSTN mRNA and MyoG mRNA expression in breast muscle of Zi goose were significantly higher than that of Rhine goose and the level of MSTN in leg muscle of Rhine was significantly higher than that of Zi goose (p<0.01). There was a significant difference between MSTN mRNA expression in breast muscle and in leg muscle of Zi goose (p<0.01). MSTN mRNA expression in leg muscle was significantly higher than that of breast muscle of Rhine goose (p<0.05). There was a significant difference between MyoG mRNA expression in breast muscle and in leg muscle of Zi goose and Rhine goose (p<0.01). There was a negative correlation between MSTN mRNA expression in breast muscle and body weight, breast muscle weight and breast muscle percentage.
