| ABSTRACT The objective of the study was to investigate the mechanism by which dietary energy concentration regulates laying performance in geese. Eighty 558-day-old female Sichuan White geese were randomly allotted to two dietary treatments, each treatment was fed 1 of 2 experimental diets containing 10.00 (deficient) or 11.80MJ/kg metabolizable energy (sufficient) for 30 days. Laying performance, hormone concentration and gene expressions in hypothalamus-pituitary-gonadal axis were examined in geese. Birds fed the sufficient-energy diet had significantly higher average egg weight, daily laying rate, and lower feed to egg ratio than those fed the deficient-energy (p<0.05). The birds fed sufficient-energy diet had higher concentration of serum insulin... |

| ABSTRACT The objective of this work was to investigate the effect of feeding conditions on methylation status of FATP1 gene, which is an important candidate gene of Intramuscular fat and important indicator of chicken meat quality. We selected Daninghe (DNH) and Qingjiaoma (QJM) chickens under scatter-feeding and captivity-feeding conditions as experimental animals, and detected the methylation status of FATP1 genes in chicken breast muscle using Bisulfite Sequencing PCR method. The results showed that the methylation level of FATP1 in scatter-fed chicken was lower than in captivity-fed conditions in DNH and QIM chicken breast tissues; DNA methylation in the promoter and exon1 region was demonstrated to negatively regulate the expression of the FATP1 gene.... |
