在鸡饲料中添加富含多不饱和脂肪酸(PUFAs)的亚麻籽,观察其对鸡血清总胆固醇(TC)、甘油三脂(TG)的影响,并与常规饲料组进行比较。选产蛋鸡20只,分为4组(对照组和添加低、中、高剂量亚麻籽组),喂养4个月,测定鸡血清中TC、TG含量。结果表明:添加低、中、高剂量亚麻籽组鸡血清中TC均显著低于常规饲料组(P<0.05);高剂量组鸡血中的TG显著低于常规饲料组(P<0.05)。因此,富含n-3多不饱和脂肪酸(PUFAs)的亚麻籽具有良好的降低血脂的作用,值得进一步研究和开发。
The flaxseed rich in polyunsaturated fatty acids (PUFAs) was added to the chicken feed to observe its effect on chicken serum total cholesterol (TC) and triglyceride (TG), and compared with the conventional feed group. 20 laying hens were selected and divided into 4 groups (control group and low-, medium- and high-dose flaxseed group). After feeding for 4 months, the levels of TC and TG in chicken serum were determined. The results showed that the serum levels of TC in chickens fed with low, medium and high doses of flaxseed were significantly lower than those in the conventional feed group (P<0.05). The TG in chickens fed the high-dose group was significantly lower than that in the conventional feed group (P<0.05). Therefore, flaxseed rich in n-3 polyunsaturated fatty acids (PUFAs) has a good lipid-lowering effect and is worthy of further research and development.
