Three objectives were included in this research work. The first objective compared different immune components in healthy mature males, mature females, and female kids of local and imported Saanen goats, reared under a sub-tropical environment. The significantly differing immune components were the blood monocyte percent, blood CD8 count, and the total white blood cell count. The second objective compared the performance of Saanen versus local does. The means of the milk yield and prolificacy of the imported Saanen does were significantly higher than those of the local does (p<0.05). The third objective compared the immune responses (hemagglutination-HA titers) and complement fixation (CF) titers in mature does of the two breeds to chicken red blood cells (c-RBC). The HA titers showed a significant seroconversion only in imported Saanen (p<0.05) but not in local does; however, the CF titers increased significantly at 4 weeks following priming with c-RBC in local (p<0.05) but not in the imported Saanen does. The impact of the differences in blood immune components and responses to antigens in the compared goats on protection potential against prevalent diseases in the sub-tropical zone of the eastern Mediterranean countries is discussed.
本研究工作包含三个目标。第一个目标是比较在亚热带环境下饲养的本地和进口萨能山羊的健康成年雄性、成年雌性和雌性幼崽的不同免疫成分。显著不同的免疫成分是血液单核细胞百分比、血液CD8计数和白细胞总数。第二个目标是比较萨能山羊与本地母羊的生产性能。进口萨能母羊的产奶量和繁殖力均值显著高于本地母羊（p<0.05）。第三个目标是比较两个品种成年母羊对鸡红细胞（c-RBC）的免疫反应（血凝-HA效价）和补体结合（CF）效价。HA效价仅在进口萨能山羊中显示出显著的血清转化（p<0.05），而在本地母羊中未显示；然而，CF效价在本地母羊用c-RBC免疫后4周显著升高（p<0.05），而在进口萨能母羊中未升高。文中讨论了所比较山羊的血液免疫成分和对抗原反应的差异对东地中海国家亚热带地区常见疾病防护潜力的影响。
