Hypothesis
How has antimicrobial use in livestock in Japan changed from 2011 to 2022?
Conclusion
The study found that while antimicrobial sales volumes fluctuated, the mg/kg biomass index provided a clearer picture of antimicrobial use trends in different livestock species.
Supporting Evidence
- Tetracycline accounted for 39% of antimicrobial sales in 2022.
- The peak antimicrobial sales volume was 847 tons in 2017.
- AMU tended to increase in beef cattle and dairy cattle, while it decreased in pigs and broilers.
- The mg/kg biomass index provided a more stable measure of antimicrobial use trends than sales volume alone.
Takeaway
This study looked at how much medicine is used for animals in Japan over 11 years. It found that some animals are using more medicine while others are using less.
Methodology
The study analyzed antimicrobial sales data and livestock biomass from 2011 to 2022 to calculate antimicrobial use per kg of biomass.
Limitations
The analysis was based on sales data, which may not accurately reflect actual antimicrobial use on farms.
