| ABSTRACT The melanocortin 1 receptor (MC1R) gene plays a key role in controlling the deposition of melanin. In mammals, the MC1Rgene is regarded as a major candidate gene in the control of melanin formation. In domestic animals, the MC1R gene mainly controls the expression of coat, skin, and plumage color in mammals and birds. In order to breed chickens with dark-green shank faster, we screened the molecular markers for shank color in a HS chicken population by exploring the relationship between polymorphism of the MC1R gene and three different shank colors (light green, dark green and yellow). Two primer pairs for code region of the MC1R gene were designed in the basic of chicken genomic sequence. DNA sequencing was performed to detect the polymorphisms... |

| ABSTRACT The objective of this study was to analyse the impact of dietary vitamin E supplementation on laying performance, serum reproductive hormones concentration and gene expression in ovary and follicles of anti-season breeding goose. A total of 210 anti-season breeding geese were divided into seven treatments with six replications. Each group was supplied with diets containing different vitamin E (DL-α-tocopherol acetate) contents (0, 10, 20, 40, 80, 160, 320mg/kg). We observed that the egg production and laying rate improved significantly at doses of 10 and 80 mg/kg, while the highest egg weight appeared in the 320 mg/kg group. Meantime, 80 mg/kg of vitamin E supplementation significantly improved the concentration of follicle-stimulating hormone... |

| ABSTRACT Chinese indigenous chicken breeds are geographically widespread, and a total of 116 indigenous chicken breeds are listed as Chinese national genetic resources. However, these indigenous chicken breeds are facing serious challenges as declining population and germplasm degeneration because lots of commercial chicken breeds had been introduced. In this study, the genetic variations of eleven Chinese indigenous chicken breeds of Sichuan province and three commercial chicken breeds were investigated based on the partial mitochondrial DNA D-loop of 487bp in length. 147 individuals from 14 breeds were examined and 34 haplotypes were observed. Genetic diversity analysis showed that the highest haplotype diversity level was found in Dahen Chicken (DH)... |

| ABSTRACT Over-accumulation of triglycerides (TGs) in goose hepatocytes leads to the formation of fatty acid liver. Phosphoenolpyruvate carboxylase kinase 1 (PEPCK) is regarded as the rate-limiting enzyme for gluconeogenesis, and there is evidence that PEPCK is involved in regulating hepatic glucolipid metabolism. Hence, we proposed that PEPCK may have a role in goose hepatic steatosis. To test our hypothesis, the present study was conducted to firstly determine the sequence characteristics of goose PEPCK and then to explore its role in overfeeding-induced fatty liver. Our results showed that goose PEPCK encodes a 622-amino-acids protein that contains highly conserved oxaloacetate-binding domain, kinase-1 and kinase-2 motifs. PEPCK had higher mRNA levels in... |
