leptin在母羊繁殖周期的作用
基本信息
结项摘要
新疆生产建设兵团拥有国内数量最多、品质最好的细毛羊，而绵羊季节性发情明显成为制约我区绵羊产业化进程的主要因素之一。通过对由下丘脑、垂体及靶腺内一系列与动物生长发育密切相关的激素、受体、相关蛋白等所组成的神经内分泌生长轴进行调控，进行绵羊非繁季节繁殖显得及其重要。本研究通过RIA、分子筛层析、RT-PCR方法检测leptin、OB-Rb在血清和组织中的表达含量，调节leptin在乏情期不同时间的表达水平，再结合现有的繁殖技术，实现方便实用、有效的进行反季节生产繁殖。基于这种假设，首先要全面了解leptin和生殖激素对母羊发情和乏情中是如何协同作用的。研究其作用规律和特点，为更加准确、有效地进行反季节繁殖提供可靠的科学依据和技术支持。
