Summary: The relationship between antimicrobial use and the occurrence of antimicrobial resistance in cattle was investigated in this study. Three types of production system were investigated for 2 years, for a total of 25 herds: 10 dairy, 10 beef, and 5 veal herds. Two different types of bacteria were sampled for the monitoring of intestinal and nasal resistance. The use of antimicrobials was recorded on 15 of these farms (5 of each production type). Antimicrobial resistance rates for 12 antimicrobial agents demonstrated large differences between intensively reared veal calves and more extensively reared dairy and beef cattle. Data analysis showed a strong relation between intensity of antimicrobial use and increased resistance. Antimicrobials given in orally in low doses and antimicrobials used preventively as group medication promoted the rise of multi-drug resistance in bacteria from the digestive and respiratory system.
