| ABSTRACT Insulin-like growth factor binding protein-2 (IGFBP-2) regulates a broad spectrum of biological activities involved in growth, development, and differentiation. This study aimed at comparing polymorphisms in intron2 of the IGFBP-2 gene among four chicken breeds and at analyzing the associations between its genotypes and body weight in Jinghai Yellow chicken by using PCR-SSCP technique. For primer P2, three genotypes (AA, AB and BB) were observed in the four chicken breeds. Gene sequencing revealed one insertion/deletion (the inserted/deleted TC after position 552bp) in the intron 2 of IGFBP-2 gene. For primer P5, three genotypes were identified in Jinghai Yellow chickens, and named CC, CD and DD. Gene sequencing revealed two SNPs (C1107G, C1130T)... |

| 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... |
