葫蔓藤抗鸡球虫病初步研究

Preliminary study of Gelsemium elegans resistance of chicken coccidiosis

试验取已感染柔嫩艾美耳球虫的4周龄艾维茵(Av500)肉鸡20只,分为Ⅰ、Ⅱ、Ⅲ、Ⅳ组,分别灌服0、5、10和20ml质量浓度为0.04g/ml的葫蔓藤全株粉悬液;一周后发现随着灌服液量的增加,鸡血便的症状逐渐消失,粪便中柔嫩艾美耳球虫卵囊的数量明显减少。体外试验发现经葫蔓藤全株粉悬液处理的柔嫩艾美耳球虫卵囊出现了扭曲、孢子化不完全的现象,且能观察到柔嫩艾美耳球虫卵囊数量减少,说明葫蔓藤对未孢子化柔嫩艾美耳球虫卵囊具有明显的破坏作用。

Twenty Av500 chickens of 4-week-old infected with Eimeria tenella were equally divided into control group（ Ⅰ ） and infected group（ Ⅱ、Ⅲ、Ⅳ）, garaged with fed with 0, 5, 10, 20 ml Gelsemium elegans whole plant powder suspension concentration of 0.04 g/ml, respectively. A week later we found that with the increase of liquid amount, the symptoms of chicken blood stool gradually disappeared and the number of oocysts reduced significantly. By the vitro treatment of Gelsemiurn elegans whole plant powder suspension, the phenomenon of distorted and incomplete spores appeared in occysts, and the number of oocysts reduced, indicating that the Gelsemium elegans had obvious influence on unsporulated oocysts infected with Eimeria tenella.
