| The experiment was conducted to evaluate the effects of different dietary vitamin combinations on the egg quality and vitamin concentrations in the eggs of commercial laying hens. A total of 1,800 25-week-old Lohman pink-shell hens were randomly assigned to four dietary vitamin treatments as follows: NRC(1994) level, NRC (1994) level with Hy.D® (25-hydroxy-cholecalciferol), Local level (current average industry level in China) and OVN® level (optimum vitamin nutrition level), with 10 replicates per treatment and 45 layers per replicate. Hens were housed in commercial laying cages with three birds per cage and given ad libitum access to feed. Results showed the hens that received the fortified vitamin levels in the OVN® treatment had a significantly... |

| 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.... |
