摘要
为了培育抗甲肝3型(DHAV-3)病毒北京鸭新品系,本实验以F_0代北京鸭为基础群体进行人工感染,然后将高生存率家系的公母鸭作为F_1代试验组的亲本。统计两代的死亡情况,并比较两代的DHAV-3检出率。结果表明:F_0代的88个家系中生存率为100%的家系有9个,生存率为0%的家系有14个。F_0代总生存率为40.96%。F_1代试验组的生存率为97.78%,极显著高于F_0代试验组的生存率(P<0.01)。F_0代DHAV-3的检出率高于F_1代。表明通过遗传选择能提高北京鸭对肝炎病毒的抗性,为下一步大规模抗DHAV-3北京鸭育种提供可参考的依据。
The Peking ducks of F0 generation were c onducted with DHAV-3 inoculation to breed a new strain of Peking ducks resistance to DHAV-3 virus followed by taking the female and male ducks in low mortality families as the parents of of Fj generation. The results showed that the F0 generation had 88 families, in which there were 9 families whose survival rate was 0% and 14 families whose survival rate was 100%. The total survival rate of F0 generation was 40.96%. The survival rate of F1 generation was 97.78%, which was significantly higher than that of F0 generation. The detection rate of DHAV-3 in the F0 generation was higher than that of F1 generation. The results showed that the resistance to DHAV-3 virus could be improved by genetic selection, which could provide valid theory basis for the further large scale of breeding of ducks.
