Abstract: The study aims to investigate resistance of Escherichia coli isolates from cow dung at different cattle growth stages to commonly used antibiotics in a cattle farm in Ili, Xinjiang. Fecal samples were taken from fattening cattle, breeding cattle, strengthen fattening cattle and non-breeding cattle. Minimal inhibitory concentrations of the Escherichia coli isolates were determined by the broth micro-dilution method. Results showed that isolation rate of Escherichia coli from fattening cattle, breeding cattle, strengthen fattening cattle and non-breeding cattle were all 100%; Escherichia coli of different cattle growth stages showed resistance to ampicillin, resistance rates were 4.0%, 8.6%, 6.7% and 20.0%, respectively, and were more sensitive to apramycin. Resistant of Escherichia coli isolates of non-breeding cattle was more serious than that of the others. Multi-drug resistance of Escherichia coli isolates from cattle at different growth stages was less serious, and most of the isolates were resistant to zero and one antibiotic. While the level of drug resistance is not very high, rational drug application should be observed in production.
