Abstract: In order to improve professional knowledge of pig-raising farmers and strengthen the rational use of veterinary drugs and monitoring of the drug residues, we investigated the basic information of medium-size and small pig farms and the use of veterinary drugs in the process of breeding in Shandong area through a variety of ways. Findings indicated that preventing drugs currently used on pig farms were mainly antibacterial drugs, Chinese traditional medicines, antiparasitic drugs, nutrient and antiviral drugs, and the remedial drugs used were mainly Chinese traditional medicines, antiviral drugs and antiparasitic drugs. Chinese traditional medicines were mainly for improving the body immunity and preventing virus diseases. Parasitic diseases were primarily based on prevention. During the investigation, some inhibitory drugs have been found still in use on some farms, so we should strengthen the supervision.
