| 摘 要： | 本文报道了在规模化养鸭中应用鸭瘟鸭病毒性肝炎二联弱毒疫苗防制鸭瘟和鸭病毒性肝炎的适用的免疫程序。试验采用了测定血清中相应抗体液度以及免疫鸭抵抗鸭瘟强毒攻击的能力和免疫鸭的下一代雏鸭抵抗鸭肝炎病毒强毒攻击的能力来进行判定。试验结果表明，种鸭鸭瘟鸭病毒性肝炎的免疫防制，使用鸭瘟鸭病毒性肝炎二联弱毒疫苗首次免疫的适宜时间为28－30日龄，二免时间为产蛋前即23－24周龄．这样在60周龄内可使种鸭不发生鸭瘟和下一代雏鸭不发生鸭病毒性肝炎。对于1－30日龄阶段的小鸭鸭瘟和鸭病毒性肝炎的防制主要是依靠母源抗体和环境的隔离、消毒来实现的。

| Abstract: | A practical imune-procedure of applying bivalent attenuated vaccines against Duck Plague (DP) and Duck Viral Hepatitis (DVH) precaution DP and DVH in scale duck farms was reported in this peper. The test was determined by assying corresponding antibody titers in serum and immuned ducks resistance to virulent DPV and the filial generations of immuned ducks resistance to virulent DHV. The result indicated that the first immunine time that DP and DPH bivalent attenuate vaccine should be used at the age of 28-30 day-old. The second is at the age of 23-24 weeks (before breeding ducks laying eggs). So the breeding duck was able to resist against virulent DP and the filial generation of immuned ducks resist against virulent DHV within the age of 60 weeks. For duckling at the age of 1-30 day-old. DP and DVH was prevented by amternal antibody, seperation and sterilization ofenvironment. |
