中文摘要:

研究了不同水平泽泻提取物对绿壳蛋鸡生产性能、蛋品质、血清生化指标和蛋黄胆固醇含量的影响。实验选用190日龄体况良好、产蛋率接近的绿壳蛋鸡225羽，随机分成5组，每组3个重复，每个重复15羽鸡。空白对照组不含泽泻添加物，阳性对照组添加0.58 mg/kg洛伐他汀，给药组分别添加0.1%、0.3%、0.5%的泽泻提取物，实验期42 d。结果表明，与空白对照组相比，质量分数0.5%泽泻提取物提高产蛋率12.28%；质量分数0.3%泽泻提取物能显著降低蛋黄胆固醇质量分数24.2%和甘油三酯质量分数35.5%；质量分数0.3%泽泻提取物能显著降低血清胆固醇质量分数51.97%；质量分数0.1%泽泻添加物组的能显著提高免疫水平。由此可见，一定剂量的泽泻提取物能降低鸡蛋和血清中胆固醇含量、提高鸡蛋品质和鸡群免疫水平，最佳添加量为质量分数0.3%。

英文摘要:

The effects of Alisma orientalis extracts with different concentration on the production performance，egg quality，serum lipid indexes and yolk cholesterol content of green-eggshell chickens. Five groups of 190-day-old green-shell chickens with a similar laying rate were randomly assigned from 225 chickens. In each group，there were 3 replicates with 15 laying chickens per replicate. The blank control group was fed without the extracts of Alisma orientalis，while the positive control was fed with 0.58 mg/kg Lovastatin. The experimental group had 0.1%，0.3% and 0.5 % extracts of Alisma orientalis，respectively，for 42 days. The egg production rate was increased by 12.28 % with 0.5 % extracts of Alisma orientalis compared with the blank control group. The egg yolk cholesterol was significantly reduced by 24.2% using 0.3% extracts，while 35.5% decrease for triglyceride levels and 51.97% decrease for serum cholesterol. The immune index was greatly improved by 0.1% extracts. A certain dose of Alisma orientalis extracts could thus reduce the cholesterol level of egg and serums，to improve the quality of eggs and chickens immunity. The optimal dosage was recommended as 0.3%.
