Easy explanation: Bovine 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. It increases milk production by about 10%.
