你需要读一下这段文章。牛的生长激素对人是无效的。

All milk contains a naturally occurring bovine growth hormone known as bovine somatotropin (BST) in very small amounts. Some dairy producers administer the synthetic version of this hormone, called rBST, to increase milk production in their cows. The U.S. Food and Drug Administration has concluded that milk produced by either treated or untreated cows is exactly the same. During pasteurization, 90% of these hormones are destroyed. The remaining trace amounts are completely digested into inactive fragments in the gut. Both hormones are specific to cows and have no effect on the human body. Thus, the hormones in milk are not a valid explanation for early puberty.
