家畜转基因抗病育种研究进展

Progress of Transgenic Technology in Disease Resistance Breeding of Livestock

人们一直期望畜产品产量和动物健康水平能快速得到提高,DNA重组技术和转基因技术的出现使得其在不同物种间,甚至不同系统发育领域间成为可能。转基因、动物克隆等技术的进步在一定程度上已经实现了在动物转基因领域的期望。本文讨论了当前家畜转基因技术和转基因抗病育种的研究近况,并对转基因抗病动物的发展进行了展望。

There was a constant expectation for fast improvement of livestock production and animal health. The advent of DNA recombinant and transgenic technology made it possible to implement gene transfer between organisms of different species, or even different phylogenic systems. The recent progress in gene transfer, animal cloning techniques had partly fulfilled the expectation in the field of livestock transgenesis. This paper reviewed the recent progress of transgenic technology and its application in disease resistance breeding of livestock. Finally, the tendency of transgenic technology in disease resistance breeding was discussed.
