Doxycycline, also known as doxycycline hydrochloride and deoxyoxytetracycline, is a highly effective, broad-spectrum, low-toxic semi-synthetic tetracycline antibiotic. Its antibacterial spectrum is similar to that of oxytetracycline, but its effect is 2 to 10 times stronger. In the pig industry, it is currently mainly used for the prevention and treatment of eperythrocytes. In addition, it can be used to treat colibacillosis, salmonellosis mycoplasmosis and psittacosis.
