重组牛生长激素(rBST)主要被用来注入奶牛体内以增加其牛奶产量。

牛生长激素英语:bovine somatotropinbovine growth hormone,缩写bSTBSTBGH)是牛脑垂体分泌的一种肽类激素,用于调节代谢过程、促进动物生长。研究发现将BST注入母牛体内可以增加其产奶量。[1]

自1970年代基因泰克发现了控制合成BST的基因后[2],使用重组DNA技术人工合成重组牛生长激素英语:recombinant bovine somatotropinrecombinant bovine growth hormone,缩写rBSTrBGH)成为了可能。此后,孟山都美国氰氨公司礼来公司普强公司等大型企业相继开发开发出了商用rBST并提交美国食品与药品管理局审核。[3][4]孟山都是其中最早获得批准的公司。除美国外,墨西哥巴西印度俄罗斯等数十个国家也都批准了rBST的商用。[5]

不过,加拿大澳大利亚新西兰日本以色列欧盟阿根廷等国家地区则禁止了市场上的rBST。

美国食品与药品管理局[6]世界卫生组织[4]国立卫生研究院[7]等机构聲稱使用rBST的奶产品及肉类对人类是安全的。不过在美国,由于部分公众的疑虑,一些生产厂家会在牛奶上贴上“不含rBST”的标签。[8][9][10][11]
