摘要
试验选用1日龄健康爱拔益加(AA)肉鸡和北京油鸡公雏各72只。检测新城疫抗体效价,牛血清白蛋白抗体水平,外周血T、B淋巴细胞转化率以及T淋巴细胞亚群等指标。结果表明:北京油鸡二免后第7天的新城疫抗体效价和二免后第6天的牛血清白蛋白抗体水平都比AA肉鸡的高,但均无显著性差异(P>0.05)。北京油鸡的脂多糖(LPS)刺激指数始终比AA肉鸡的高(P>0.05);21日龄时,北京油鸡的刀豆素(A ConA)刺激指数、CD4+、CD8+T淋巴细胞数量以及CD4+/CD8+都比AA肉鸡的高,但均无显著性差异(P>0.05);而42日龄时,AA肉鸡的ConA刺激指数、CD4+、CD8+T淋巴细胞数量以及CD4+/CD8+却高于北京油鸡(P<0.05)。本试验结果提示,AA肉鸡和北京油鸡的体液免疫和细胞免疫功能之间存在一定的差异,但差异不显著。
This study was conducted to investigate the humoral immunity and cellular immunal function between Arbor Acre（AA） and Beijing fatty chickens. The results showed that the antibody titers to NDV at 28 d and the anti- BSA antibody production at secondary response 6 d of Beijing fatty chickens were higher than that of AA chickens（P 〉 0.05）. The proliferation of peripheral blood B lymphocyte of Beijing fatty chickens were higher than that of AA chickens（P〉 0.05 ）. At 21 days, the proliferation of peripheral blood T lymphocyte, CD4^＋ T lymphocyte amount, CD8^＋ T lymphocyte amount, and CD4^＋/CD8^＋ of Beijing fatty chickens were higher than that of AA chickens（P 〉 0.05 ）, but at 42 days, the proliferation of peripheral blood T lymphocyte, CD4^＋ T lymphocyte amount, CD8^＋ T lymphocyte amount, and CD4^＋/CD8^＋ of AA chickens were higher significantly than that of Beijing fatty chickens （P 〈 0.05 ）. In conclusion, there were not significantly differences in humoral and cellular immunal function between Arbor Acre and Beijing fatty chickens.
