重组猪生长激素表达研究进展

猪生长激素作为猪生长发育过程中起主导作用的蛋白质激素，能增加肌肉组织蛋白含量、降低脂肪含量、促进骨骼发育、刺激乳汁分泌等，是畜牧养殖业中值得开发利用的激素之一。利用基因工程技术生产重组猪生长激素使猪生长激素在生产上应用成为可能。本文简要介绍了猪生长激素，总结了重组猪生长激素表达的研究进展，并展望了重组猪生长激素的应用与发展前景。

Progress on Expression of Recombinant Porcine Growth Hormone

Porcine growth hormone (pGH), a protein hormone that plays a leading role in the process of pig's growing development, is one of useful hormones worth developing and utilizing in animal husbandry, since it can increase muscle protein content，reduce fat content，promote bone growth，and stimulate lactation，etc. The development of recombinant porcine somatotropin hormone by genetic engineering techniques make it possible for pGH's applications in the pig production. This paper briefly described the porcine growth hormone，summarized the research progress of recombinant porcine growth hormone expression，and forecasted the prospect of the application and development of recombinant porcine growth hormone.
