不同饲养模式对黄山黑鸡禽流感及新城疫抗体水平的影响

Effect of Different Rearing Patterns on Antibody Levels of Avian Influenza and Newcastle Disease of Huangshan Black Chicken

为比较黄山黑鸡笼养和山间林地散养时禽流感和新城疫的免疫效果,分别对黄山黑鸡笼养群体和散养群体17-25周每周随机抽取相同数量的个体采集血清后进行免疫抗体检测。结果显示,笼养组禽流感抗体效价最低为8.3,最高为9.9,散养组禽流感抗体效价最低为8.8,最高为9.8,散养组9周平均抗体效价为9.4,显著高于笼养组平均抗体效价9.1（P〈0.05）;笼养组新城疫抗体效价最低为5.8,最高为7.4,散养组最低为6.0,最高为6.9,两组差异不显著（P〉0.05）。研究表明,黄山黑鸡散养模式下禽流感抗体平均效价显著高于笼养模式,新城疫抗体平均效价差异不明显。

To compare the Avian Influenza（AI） and Newcastle disease（ND） of Huangshan black chick- en reared in cage or free range, the antibody level of AI and ND were detected every week from week 17 to 25 in two rearing patterns. The results showed that the average antibody value of AI in cage population was 8.3 to 9.9, and that of free range were 8.8 to 9.8 ; the antibody level of ND in cage population was 5.
