Dairy: Hormones are used in about 15 percent of dairy cows in the U.S. to increase milk production.

Pork: No hormones are used to promote the growth of pigs in the U.S. Rather, hormones can be given to assist sows during birth. Like humans, they receive Oxytocin to aid the sow during labor.

Poultry: No hormones are used to promote the growth of poultry in the U.S.
