| Abstract: | The aim of this study was to investigate the effects of MSTN and MyoG genes on goose skeletal muscle growth.In this study,MSTN and MyoG genes expression were detected in breast and leg muscle of Zi and Rhine goose by Real-time PCR,and the correlations between genes expression levels and carcass traits were investigated.The results showed that the breast muscle weight and breast muscle rate of Rhine goose were extremely significant higher than Zi goose (P<0.01).MSTN and MyoG mRNA expression in breast muscle of Zi goose were significantly higher than that of Rhine goose,and the mRNA level of MSTN in leg muscle of Rhine was extremely significant higher than that of Zi goose (P<0.01),there was no significant difference of MyoG mRNA between Zi goose and Rhine goose (P>0.05).There was extremely significant difference between MSTN mRNA expression in breast muscle and 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 extremely significant difference between MyoG mRNA expression in breast muscle and leg muscle of Zi goose and Rhine goose (P<0.01).There was a extremely significant negative correlation between MSTN mRNA expression in breast muscle with body weight,breast muscle weight and breast muscle percentage (P<0.01).There was a extremely significant positive correlation between MyoG mRNA expression in breast muscle and leg muscle with body weight (P<0.01).MSTN and MyoG gene might have positive and negative regulation effect on muscle growth. |
