猪深部输精技术的运用

The Highlights of Post-cervical Artificial Insemination in Sows

猪深部输精技术是一项逐步被规模化猪场接受并使用的繁殖技术。与常规输精相比,该技术不仅能保证母猪的繁殖成绩,还能节约近一半的精液量。然而,很多规模化猪场对于该技术的使用仍不规范,因此本文主要从适时输精、输精深度、输精量和操作方法等方面进行综述,旨在为猪深部输精技术的使用提供指导。

In recent years, post-cervical artificial insemination （Post-CAD in sow is a new breeding technique gradually accepted and applied by intensive pig production. Compared with conventional insemination, this technique can not only guarantee the reproductive performance of sows, but also save nearly half semen volume. However, at present, many large-scale pig farms for use of the technology is still irregular. This paper reviewed insemination time, insemination depth, insemination semen volume, operation methods and other aspects, hoping to provide guidance to swine Post-CAI work.
