In the United States, it is legal to give a bovine GH to dairy cows to increase milk production, and is legal to use GH in raising cows for beef; see articles on Bovine somatotropin, cattle feeding, dairy farming and the beef hormone controversy.
Several companies have attempted to have a version of GH for use in pigs (porcine somatotropin) approved by the FDA but all applications have been withdrawn [REF].
