蓝黄青口服液对鸡传染性喉气管炎疫苗免疫的影响

Effect of LHQY on Immunity Efficacy of Chicken Infectious Laryngotracheitis

为测定蓝黄青口服液(LHQY)对鸡传染性喉气管炎(ILT)免疫以及红细胞免疫力的影响,试验分为4组,分别为对照组、LHQY(浓度为1:1500)饮水组、鸡传染性喉气管炎和鸡痘基因工程活载体疫苗免疫组和二者同时给予组。结果显示,LHQY给药后3d就能极显著提高健康鸡的RBC-CR1花环率和RBC-IC花环率(P<0.01),并且这种作用效果可以持续20d以上;与疫苗同用,RBC-CR1花环率和RBC-IC花环率均显著或极显著高于健康对照组和疫苗组(P<0.05,P<0.01)。进行攻毒保护试验,发现LHQY用药组的RBC-CR1花环率和RBC-IC花环率均极显著高于感染对照组(P<0.01),LHQY与疫苗混合使用这两种花环率也极显著高于感染对照组(P<0.01),并整体高于疫苗组。说明蓝黄青口服液能显著提高鸡红细胞免疫功能,对ILT有很好的预防和治疗作用。

The effect of LHQY on prevention of ILT and erythrocyte immunity were studied in this paper. The trial had 4 treatments. There were control group,adding LHQY group,immunization group by the genetic engineering vehicle vaccine of ILT and varicella,and LHQY and vaccine group. The results showed that the chaplet rate of RBC-CR1 and RBC-IC were both increased in health fowls when the LHQY was given 3 days （P〈0.01）,and this effect last 20 days. If LHQY and vaccine were given to fowls simultaneously,the chaplet rate of RBC-CR1 and RBC-IC were both significantly higher than that of control group and vaccine group （P〈O.O5,P〈O.O1）.To determine the effect of LHQY on the prevention against ILTV,the results showed that the chaplet rate of RBC-CR1 and RBC-IC in LHQY group were significantly higher than that of infective control group （P〈0.01）. If LHQY and vaccine were given to fowlssimultaneously,the chaplet rate of RBC-CR1 and RBC-IC were significantly higher than that of infective control group and vaccine group （P〈0.01）. The results showed that LHQY have the prevental and therapeutical effect on ILT.
