Abstract: Background: Surveillance of antimicrobial use (AMU) in food animals is the key strategy to tackle the problem of antimicrobial resistance. Aim: A cross-sectional period prevalence survey was conducted to collect AMU data from 12 dairy farms from two provinces (Punjab and KP) in Pakistan. Methods: AMU data were analyzed using three metrics, i.e., antimicrobial chemical compound (ACC in kg), (mg/PCU), and (DDDA/1,000 animal-days). Results: The total usage in adult dairy cattle in terms of mg/PCU and treatment incidences across both seasons and all provinces were 6.36 mg/PCU and 26.34 DDDA/1,000 animal-days. However, in adult dairy cattle cumulative AMU across both seasons and provinces was 15.23 kg, 6.36 mg/PCU, and 26.34 DDDA/1,000 animal-days whereas in calves the figures were 1.22 kg, 8.58 mg/PCU, and 36.71 DDDA/1,000 animal-days. Treatment incidences in winter were 23.9% lower in adult dairy cattle and 65% lower in calves compared to summer. In adult dairy cattle, 17.35% of antimicrobials used were HPCIAs. Conclusion: These findings highlight the need for countrywide AMU monitoring and regulations on HPCIAs in food animals.
