摘 要:为评价两种球虫疫苗对京海黄鸡杂交配套系亲本良凤鸡(BB鸡)和岭南黄鸡(FF鸡)的免疫效果,本研究对9日龄实验鸡接种两种疫苗[500个孢子化卵囊(V1组)、正典球虫苗(V2组)],24 d后攻柔嫩艾美耳球虫(E.tenella)2.5万个/只,攻虫后8 d检测各项评价指标。结果显示:攻虫后临床表现、盲肠病变、相对增重率及抗球虫指数(ACI),BB鸡优于FF鸡,V1组优于V2组;两鸡群血浆中过氧化氢酶(CAT)、超氧化物歧化酶(SOD)的含量V1组均显著高于V2组(p<0.05);BB鸡γ干扰素(IFN-γ)含量V1组显著高于V2组(p<0.05);FF鸡血浆中β胡萝卜素(β-C)含量V1组显著高于V2组(p<0.05)。综合分析表明,BB鸡E.tenella抗性优于FF鸡,500个E.tenella活卵囊免疫效果优于正典球虫疫苗。In this study, Jinghai Yellow chicken cross-breeding system parental BB and FF were vaccinated two vaccines of 500 live Eimen'a tenella sporulated oocysts (V1) and standard coccidiosis vaccine (V2) at 9-day-old, and challenged with 2.5×10^4 sporulated E.tenella oocysts at 24 days post vaccination (PV). Then, all evaluation parameters were examined at 8 days post challenge (PC) for evaluating the immune effects of two coccidiosis vaccines in BB and FF. The results showed that BB chickens were not serious to FF chickens in clinical signs, lesions in the cecum, relative growth rate, and ACI values post PC. And also the vaccine V1 was more efficient against coccidiosis than that of vaccine V2. The plasma parameters of CAT, SOD in V1 group were significantly higher than that of V2 group (p〈0.05). For BB, the IFN-γ levels in group V1 were significantly higher than that in group V2 (p〈0.05). As for FF chickens, the β-C levels in group V1 were significantly higher than that in group V2 (p〈0.05). Comprehensive analysis shows that the E.tenella resistance of BB chickens was superior to FF chickens, the immtme effect of group V1 was superior to group V2.
