Growth promoters can be classified into four groups; those that increase growth and also increase feed consumption, those that increase growth without altering feed consumption, those that do not alter growth but decrease feed consumption (generally referred to as the feed consumption ratio; FCR=kg feed consumed/kg body weight), and those that increase growth and decrease feed consumption. Obviously, a growth promoter that increases feed consumption would not be a commercially viable product. Furthermore, a growth promoter that adversely alters meat quality and/or taste also would be unacceptable.
