Bovine somatotropinBovine somatotropin or bovine somatotrophin (abbreviated bST and BST), or bovine growth hormone (BGH), is a peptide hormone produced by cows' pituitary glands. Like other hormones, it is produced in small quantities and is used in regulating metabolic processes. Recombinant bovine somatotropin (usually "rBST"), is a synthetic version of the bovine growth hormone given to dairy cattle by injection to increase milk production.
