Abstract: 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.

Key words: pGH, physiological function, recombinant expression, prospect
