【摘要】 本试验将试验用鸡分为两A、B两组,A组用左旋咪唑和新城疫Lasota疫苗处理,B组只用新城LaSota疫苗处理,并按常规在7日龄和28日龄分别进行两次免疫,于处理后第14、21、35、42天用HA和HI实验检测抗体滴度,试验结果表明:第一次免疫后,14、21日龄A、B组的平均抗体滴度分别为26.1、25.6、60.5、61.0,统计处理表明,A组抗体滴度比B组抗体滴度差异不显著(t<0.796,0.794)。第二次免疫后35、42日龄A、B组的抗体滴度分别为221.6、221.2、267.3、266.3,统计处理表明,A组抗体滴度比B组抗体滴度差异不显著(t<0.864,0.714)更多还原

【Abstract】 The testing chickens were divided into two groups named group A and B, and A was treat with Levamisole and new castle disease vaccine of LaSota strain, and B was treat only with new castle disease vaccine of LaSota strain. Both of group A and B were immune at 7 and 28 old days, then antibody titer was detected by HA and HI test. At 14,21,35 and 42 old days, antibody titer of A group is 26.1,60.5,221.6 and 267.3,B group is 25.6,61.0,221.2 and 266.3 .By statistics,the result shows that the difference between A and B is quiet.更多还原
