摘要
同期发情-定时输精技术是在经典的定时输精技术基础上的延伸以及改良,目前已在全世界范围内广泛使用,可以有效提高牛的繁殖水平,避免因发情延迟或不发情等带来的经济损失。本文总结了近几年国内外在奶牛和水牛同期发情-定时输精技术中对激素配伍和输精时间等方面的改良研究进展,为奶牛和水牛的繁殖育种及相关研究提供参考。
The estrus-timed insemination technology is an extension and improvement based on the classic timed artificial insemination. Currently, estrus-timed insemination technology has been widely used all over the world, which can effectively improve the breeding level of cattle and avoid economic losses caused by prolonged estrus cycles or estrus. This paper summarized the research progress in the improvement of hormone compatibility and insemination time in dairy cows and buffalo in recent years, and provided reference for breeding and related research of dairy cows and buffalo.
