摘要
为了了解和比较免疫增效剂的作用，本研究选用了左咪唑、维生素Ｅ、转移因子、ＡＣＭ－１四种药品，对雏鸡作分组试验。共分１０组，１～５组用ＨＩ法监测鸡新城疫（ＮＤ）免疫抗体。６～１０组用ＡＧＰ法检测鸡法氏囊病免疫抗体。分别于免疫后第５、１５、２５日作三次监测。试验结果：两种疫苗免疫后均以左咪唑增效作用最大，维生素Ｅ、ＡＣＭ－１次之，最小是转移因子，但四种药均有明显效果。而左咪唑和维生素Ｅ是既便宜又实用且效果好的免疫增效剂，对ＮＤ和ＩＢＤ免疫有明显增强作用，可在生产中推广应用。
Levamisloe,vitamin E.transfer factor and ACM 1 were tested and compared as the immune enhancement reagents lang with Newcaslt disease (ND) vaccine and Infectious Bursal disease (IBD)vaccine,respectively.The efficency of these reagents for the antibody titre enhancement was determined by HI test for ND and AGP test for IBD at 5、15 and 25days of postinoculation.The result showed that all the reagents were efficently enhanced thd immune response of ND and IBD vaccine.Among the reagents ,levamisole and vitaminE were more efficent than others.Meanwhile the two reagents are the best candidate for practical application as the immune enhancement reagents due to the low cost and easy adminstration.
