What is Mecadox?
Mecadox is an antibacterial that improves pig performance in a wide range of health and growing conditions. It improves gut health by controlling enteric pathogens known to cause scours and hemorrhagic dysentery. Mecadox improves feed efficiency and rate of gain.
How does chloramphenicol work?

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.
Are there any approved new animal drug applications for carbadox?

What happens if Carbadox is no longer available?
