What is rBST?


Bovine somatotropin (abbreviated bST and BST), also known as bovine growth hormone, or BGH, is a protein hormone. BST is naturally occurring in cattle, and plays a role in the growth and development of the organism.

Since 1994 it has been possible to synthesize the hormone using recombinant DNA technology to create recombinant bovine somatotropin (rBST), recombinant bovine growth hormone (rBGH), or artificial growth hormone which stimulates the appetite of lactating dairy cows resulting in more milk production.

Kraft understands there are some concerns around rBST.  It is important to note that milk from cows given supplemental rBST has been determined to be safe by the U.S. Food & Drug Administration (FDA), the World Health Organization and regulatory agencies in a number of countries all over the world.

We also understand that some consumers are looking for dairy products made with milk from cows not treated with rBST. In the U.S., we continue to offer products with milk derived from both rBST-treated and non-rBST treated cows. The ones which do not contain milk from rBST treated cows are clearly labeled.
