摘　　要：随机抽取如皋鸡、文昌鸡及安卡鸡各80只,每个品种分为A、B2组,每组分别于49日龄腿肌注射25%绵羊红细胞(Sheep red blood cell,SRBC)0.5、1mL。分别检测了41、56、71、89日龄的异嗜性粒细胞/淋巴细胞(Hetero-phil/Lymphocyte,H/L)值,56、71、89日龄的SRBC抗体滴度以及30、41、56、71、89日龄的新城疫(Newcastle disease,ND)和禽流感(Avian influenza,AI)抗体滴度。结果显示,同一检测日龄H/L值在不同品种间存在差异,随着日龄的增加品种间的差异逐步减小;不同品种H/L值随时间变化的趋势不同,如皋鸡4个日龄变化平缓,文昌鸡和安卡鸡呈先高后低趋势。3个品种SRBC抗体滴度均在56日龄达到最高,其中文昌鸡最高,安卡鸡最低,且差异显著(P<0.05)。除如皋鸡外,其他品种对不同剂量SRBC抗原的敏感程度存在差异。在免疫ND疫苗后3个品种抗体滴度表现出相似的变化规律,但是变化幅度有所差异,安卡鸡前3个检测日龄滴度介于如皋鸡和文昌鸡之间,但免疫后期迅速上升,71和89日龄滴度极显著高于其他2个品种(P<0.001);如皋鸡和文昌鸡之间AI抗体滴度除56日龄之外均不存在显著差异,而安卡鸡在所有日龄均极显著低于其他2个品种(P<0.01)。结果表明,家禽的免疫性状在品种间存在遗传差异,中国地方鸡种比外来鸡种在多个免疫性状上存在不同程度的优势。The present study compared some immune traits to evaluate the disease resistance of different chicken breeds.Random samples of 80 chickens from each population of Rugao Chicken （RG）,Wenchang Chicken （WC）,and Anka Chicken（AK） were partitioned into A and B groups.Each group had an injection of 0.5 mL and 1 mL of 25% suspension of sheep red blood cell （SRBC） at 49 days of age,respectively.The value of heterophil/lymphocyte（H/L） at 41,56,71and 89 days of age,SRBC antibody titer at 56,71and 89 days old,and the antibody of Newcastle disease （ND） and avian influenza（AI） at 30,41,56,71 and 89 days of age were detected,respectively.The results showed as follows：The difference of H/L value existed between different breeds in the same days of age,but it became smaller along with time.H/L value in RG changed less than that of other breeds,however,WC and AK had obvious change from high to low level.The SRBC antibody titer of three breeds got the highest at 56 days,the highest with WC and the lowest AK（P〈0.05）.Moreover,there were significant differences between them.The sensitivities to different dosages of breeds were different except RG.ND antibody titer of three breeds had the change,variable,though the AK＇s antibody titer was in the mid of RG and WC before the third immunity,it was extremely significantly higher than the other two breeds of chicken after that period （P〈0.01）.There were insignificant difference of AI antibody titer between RG and WC in all test time except 56 day,meanwhile antibody titer of AK was extremely significantly lower than that of the other two breeds in all test time（P〈0.001）.This study showed that the immune traits were different between chicken breeds,and Chinese chicken breeds had the some advantage of outside breeds.
