摘要
将２００只雏鸡根据不同的处理分成四组：对照组、淫羊藿－蜂胶合剂组，ＭＤ疫苗组和疫苗－合剂组，并在１１日龄时全部用ＭＤ强毒攻击。于４、１１，２６、４１和５６Ｈ龄时采血样，测定各自的ＲＢＣ－ＣＲ，花环率和ＲＢＣ－ＩＣ花环率，同时统计各组的ＭＤ发病率。结果：ＭＤ发病率，对照组＞合剂组＞疫苗组＞疫苗－合剂组，分别为：７６％、６０％、５４％和３４％。疫苗－合剂组ＭＤ发病率极显著地低于其他组（Ｐ＜０．００５）；ＲＢＣ－ＣＲ＿１花环率，接种ＭＤＶ后，疫苗－合剂组迅速增加，并一直维持在较高水平（８．０％左右），其他组均是下降以后再缓慢回升，与ＲＢＣ－ＩＣ花环率呈反向变化关系。结果表明：淫羊藿－蜂胶合剂有明显增强感染ＭＤＶ后鸡ＲＢＣ－ＣＲ＿１活性和降低ＭＤ发病率的作用。
chickens were divided into 4 groups with diffent treatmental methods:the control group and vaccine-mixture group.All chickens were inoculated MDV on the 11th day and the RBC-CR rosetterate and RBC-IC rosette rate of their blood.samples were determined respectively at4,11,26,4 and 56 days of age,their incidence of MD and was calculated.Theincidence of MD is 76%,60%,54%and 34%respectively(control group>mixturegroup>vaccine group>vaccine-mixture>roup).After inoculation of MDV,the RBC-CR rosette rate in vaccine-mixture group increased rapidly and maintained on a highlevel.The other groups were increasing after decreasing.The RBC-CR、and RBC-ICrosette rate presented a opposite change. These results indicate that epimedium-propolismixture can develop the RBC-CR1 activity aiid decrease the incidence of MD Ofchicken after inoculation of MDV.
