Discontinuing the use of rbST will entitle the farm to an additional over-order premium. Michigan cooperatives were given a commitment for a 75 cent/hundredweight (cwt) premium to provide rbST-free milk for the Class I market for a 1-year period. This money will be part of the over-order premium.
Human growth hormone is very different in structure from bovine growth hormone and bovine rBST. The differences in the DNA structure of natural human BST and natural bovine BST means this bovine growth hormone (rBST) cannot work in the human body.omatotropin regulates the cowâs metabolism and determines how efficiently the cow converts feed into milk. Bovine somatotropin (BST) is also called Bovine Growth Hormone (BGH). Dairy farmers can now inject cows with a man-made version of bovine BST called recombinant BST (rBST).
