摘要
实验用 1 5日龄北京爱拔益加 AA肉仔鸡 1 2 0只 ,随机分为 3组 ,用新城疫弱毒苗免疫 ,然后在饲料中添加纯中药饲料添加剂方 和方 ,于不同日龄采血 ,检测血清中 HI抗体水平。结果表明 :实验组 (即纯中药添加组 ) HI抗体水平与对照组相比有升高的趋势 ;作血涂片经 α-醋酸萘酯酶染色发现 ,实验组 T淋巴细胞的阳性率显著高于对照组 ( P <0 .0 5)。证明纯中药饲料添加剂方 和方 有增强肉仔鸡体液免疫和细胞免疫的功能。
In the study, 120 Beijing AA broilers of 15 th day were randomly and divided into 3 groups. They were immuned with ND in 15 th and 31th, then PrescriptionⅠ(PⅠ)and PrescriptionⅡ(PⅡ)were added to the broilers feed. In different days ,the effect of PⅠand PⅡon broiler's HI antibody titres were investigated. The resultis as follows: PⅠand PⅡ made the HI antibody titres of the testing groups higher than that of the control group. PⅠand PⅡ made the positive rate of T lymphocytes higher than that of control group on 6 th day and 15 th day, post second immunization. So PⅠand PⅡ promoted broilers cell immunity and humoral immunity.
