液态胆汁酸对肉鸭生产性能、血清生化、肝脏脂代谢的影响OA

The aim of this study was to investigate the effects of liquid bile acid on growth performance,slaughter performance,serum biochemistry,liver and intestinal health of meat ducks.A total of 16 000 1-day-old Cherry Valley commercial meat ducks were randomly divided into 2 treatments,with 8 replicates per treatment and 1 000 ducks per replicate.The experimental period was 39 days.A single-factor randomized design was adopted.The ducks in the control group were given normal drinking water,while the ducks in the experimental group were given normal drinking water supplemented with 100 mL/t bile acid(BA).The results showed that compared with the control group,the addition of 100 mL/t BA significantly increased the fully eviscerated rate and semi-eviscerated rate of meat ducks(P<0.05),and reduced the high-density lipo-protein content of serum(P<0.05).In addition,BA significantly improved the morphology of the liver,increased the mRNA expression of the fat decomposition related gene LPL(P<0.05),while decreasing the mRNA expression of the fat synthesis related gene FAS(P<0.05).In conclusion,liquid bile acid can promote the slaughter performance,improve fat metabolism in the liver and be applied in meat duck production.
