Abstract

Abstract: In the present study,Cherry Valley ducks were subjected to diets with 4% linoleic acid and eicosapentaenoic acid (EPA) from week 2 to the end of week 10,respectively,and detected the mRNA expression of SCD-1 in 4,6,8 and 10 weeks,and analyzed its association with meat quality and serum biochemical indexes in 10 weeks.The Real-time fluorescence quantitative PCR results showed that the linoleic acid and EPA could significantly reduce the SCD-1 mRNA levels in liver,fat and breast muscles (P<0.05),meanwhile,the SCD-1 gene mRNA expression level had no significant difference between linoleic acid and EPA in every period (P>0.05).Correlation analysis showed that the mRNA expression levels of SCD-1 had significant positive correlation with serum TG,TCHO,HDL and LDL (P<0.05),and no significant correlation with all meat quality traits in 10 weeks (P>0.05).The research suggested that the transcription of SCD-1 gene was inhibited by linoleic acid and EPA,and played important role in the regulation of duck lipid metabolism.

Key words: duck; SCD-1; gene expression; meat quality; serum biochemical index
