几种单味中草药降低鸡蛋胆固醇的效果比较

Effect of Single Chinese Medicine Herb on Cholesterol Content of Egg

选择产蛋率和体重相近的42周龄罗曼褐壳蛋鸡180只,随机分成6组,每组设5个重复,每个重复6只鸡,试验期8周。以基础日粮作为空白对照组,试验组分别在基础日粮中添加1%的陈皮、山楂、姜黄、决明子、大黄,以研究5种中草药对鸡蛋胆固醇的影响。结果表明,5种中草药都能降低血浆TG、TC、LDL水平和提高HDL含量,以山楂、决明子、大黄效果明显(P<0.05);5种中草药都能降低鸡蛋胆固醇,但以山楂、决明子、大黄降低鸡蛋胆固醇作用显著(P<0.05),与空白对照组相比,蛋黄胆固醇浓度分别降低14.83%(P<0.05)、16.06%(P<0.05)、13.84%(P<0.05),鸡蛋胆固醇含量分别降低14.50%(P<0.05)、15.56%(P<0.05)、12.72%(P<0.05)。

To study the effect of five Chinese medicine herb on cholesterol content of egg, 180 Lohmann Brown Laying hens aged 42 weeks with similar body weight and laying rate were selected and randomly divided into six treatment groups ,each treatment with five replicates, each replicate with six layers. The experitment lasted for 8 weeks. The layers in control group were fed with basic diet, and the layers in the treatment groups were fed with basic diet added to by 1.0% Periearpium Critri Reticulate, Hawthorn, Rhizoma Cureumae Longae, Semen Cassiae and Rhubarb respectively. The results showed that five Chinese medicine herb deduced TG ,TC ,LDL level in the laying hens plasma and increased HDL content, but significant effect was seen from adding Hawthorn, Semen Cassiae and Rhubarb in basic diet respectively （ P 〈 0.05 ）. Compared with control group, after supplemented with Hawthorn, Semen Cassiae and Rhubarb in basic diet respectively, cholesterol content per gram yolk was significantly decreased by 14.83% （ P 〈 0.05 ）, 16.06% （ P 〈 0.05 ） and 13.84% （ P 〈 0.05 ） respectively, and the content of cholesterol per egg was significantly decreased by 14.50% （ P 〈 0.05）, 15.56% （ P 〈 0.05 ） and 12. 72% （ P 〈 0.05 ） respectively.
