What is a carbadox drug?
1. What is carbadox? Carbadox is an animal drug used in swine (hogs and pigs) for production purposes (e.g., increased rate of weight gain and improved feed efficiency) and therapeutic purposes (e.g., to control swine dysentery and bacterial swine enteritis). Carbadox is an animal drug shown to be carcinogenic in laboratory animals.
