摘要
目的:研究日粮中添加亚麻籽、VE、乙氧基喹啉对海蓝红蛋鸡生产性能及蛋黄中ω-3PUFA富集效果的影响。方法:随机选取480只48w龄的健康海蓝红蛋鸡,以不同水平亚麻籽、VE、乙氧基喹啉添加的饲料饲喂蛋鸡,测定其生产性能指标以及蛋黄中脂肪酸的含量。建立蛋黄中脂肪酸富集效果模型,确定三因素添加的最佳配比。结果:日粮中添加亚麻籽、VE、乙氧基喹啉对海蓝红蛋鸡的生产性能影响较小,试验组与对照组差异不显著(P>0.05);添加亚麻籽15%,VE0.17g/kg,而无乙氧基喹啉时,可获得最大的ω-3PUFA的富集。结论:通过对蛋鸡日粮中亚麻籽、VE含量的调控可以在不影响蛋鸡生产性能的条件下增加鸡蛋黄中脂肪酸的富集。
Objective： The effect of the linseeds, VE and ethoxyquinoline in feed on the productive performance of the Hailanhong layers and ω-3 PUFA deposition in the yolk of laying eggs was studied, Method： Four hundred and eighty healthy layers of 48 weeks of age were randomly selected, The linseeds, VE and ethoxyquinoline of different levels in diet were fed on these layers. The indices of the productive performance and the fatty acids content of yolk were determined, The regression model of the fatty acids deposition was established, Results： The effect of the linseeds, VE and ethoxyquinoline in feed on the productive performance was slight. The most deposition of ω-3 PUFA was found by adding linseeds 15%, VE 0.17g/kg feed without ethoxyquinoline. Conclusion： The deposition of ω-3 PUFA in eggs could be regulated by controlling the proportion of linseeds and VE in feed with no effect on productive performance of layers.
