Abstract: In this paper, the basic information and the status quo of use of veterinary drugs in beef cattle farms in Inner Mongolia were investigated. The results show that small-scale and medium-scale breeding of beef cattle are dominant in Inner Mongolia,and there are a variety of business patterns, while they are mainly bred by breeding cooperatives. Main therapeutic drugs are antibiotics, and gentamicin was used most frequently. In the course of breeding cattle, the epidemic diseases are respiratory diseases and digestive tract diseases, and their preferred therapeutic drugs are florfenicol, amoxicillin and colistin in Inner Mongolia. Compared with medium and large farms, the types and frequency of drugs are more in small farms. The current method of using drugs may lead to gradual enhancement of drug resistance of pathogenic microorganisms and residues of veterinary drugs in products exceeding the standard.
