摘要
随着规模化牛场养殖集约化程度的加深,妊娠检查要求在30d之前达到高准确率,但现在的早期妊娠诊断方法明显达不到要求。本文重点从免疫学方法入手,比较了不同方法针对不同内源物质在早期妊娠诊断上的技术难度、繁琐程度、成本、精确程度,以期为后续早期妊娠诊断发展和研究提供方向。
With the development of large-scale dairy farming intensification deepened, pregnancy inspection requirements before 30 days to achieve high accuracy, but the early pregnancy diagnosis method now was not up to the requirements.
