UK dairy farms have achieved a remarkable feat: slashing antibiotic use by 19% since 2020 without compromising animal health or milk production. This groundbreaking progress sets a new industry standard and addresses growing concerns about antimicrobial resistance. Discover how they did it.
Summary:
UK dairy farms have significantly reduced antibiotic use, achieving a 19% decrease since 2020 without compromising animal health or milk production. The latest Kingshay Dairy Antimicrobial Focus Report reveals that the average total antimicrobial usage in 2024 was 12.7 mg/kg PCU, well below the 2024 target of 17.9 mg/kg PCU. This reduction has been accompanied by improvements in key health indicators, including lower mastitis rates and decreased bulk somatic cell counts. The success is attributed to strategies such as Selective Dry Cow Therapy, enhanced herd management, and data-driven decision-making. While challenges remain, including potential economic impacts and the need for continued vigilance, the UK dairy industry’s progress sets a promising example for sustainable farming practices prioritizing animal welfare and public health.
Key Takeaways:
- The UK dairy farms have successfully cut antibiotic usage by 19% since 2020, surpassing targets and maintaining herd health and milk production.
- Wales demonstrated significant progress with a 31% reduction in antibiotic use.
- Mastitis and somatic cell counts have decreased, reflecting improved herd health following responsible antibiotic management.
- Antibiotic usage metrics, including dry and lactating cow tubes, show positive trends with reduced usage rates.
- Industry experts call for continued efforts to focus on reducing usage in high-use farms and advocate for adopting best practices.
In a positive development for the UK dairy industry, farms have successfully reduced antibiotic use by 19% since 2020 without negatively impacting animal health or milk production. The latest Kingshay Dairy Antimicrobial Focus Report shows that the average total antimicrobial usage 2024 was 12.7 mg/kg PCU, representing a 29% reduction from the target of 17.9 mg/kg PCU set for 2024.
Key Findings
The report, which analyzed data from 879 dairy herds across the UK, highlights several encouraging trends in reducing antimicrobial usage.
- Every UK region has excelled in surpassing the 2024 target for antimicrobial usage.
- Wales showed exceptional improvement, with a 31% reduction in antimicrobial use.
- Over half of the farms reduced their total antimicrobial usage by about 7.4 mg/kg PCU compared to the previous year.
- Antibiotic usage has decreased by 15% for cows during the dry period and while producing milk.
Dr. Tim Potter, Senior Clinical Director at Westpoint Farm Vets and co-author of the report, states that this reduction in use has positively impacted herd health and milk production, with no adverse effects observed.
Improved Herd Health Indicators
Indicator | 2019 | 2020 | 2021 | 2022 | 2023 | 2024 |
---|---|---|---|---|---|---|
Mastitis cases per 100 cows | 39 | 36 | 32 | 30 | 29 | 26 |
Somatic cell count (‘000/ml) | 161 | 164 | 163 | 161 | 159 | 159 |
Milk yield (liters/cow/day) | 28.6 | 28.5 | 28.6 | 28.5 | 29.1 | 28.4 |
Culling rate (%) | 28 | 28 | 28 | 28 | 29 | 28 |
The reduction in antibiotic use has coincided with improvements in key health indicators such as mastitis rates and bulk somatic cell counts.
- Mastitis rates have decreased to 26 cases per 100 cows, down from 29 in 2023 and 42 in 2020.
- Bulk somatic cell counts have decreased.
- There has been no increase in culling rates due to mastitis.
Strategies for Success
Several approaches have contributed to this achievement, including Selective Dry Cow Therapy (SDCT), enhanced herd management, and data-driven decision-making.
- Selective Dry Cow Therapy (SDCT): treating only cows with a high probability of infection during the dry period.
- Enhanced herd management: focusing on improved animal husbandry and disease prevention.
- Data-driven decision making: using antimicrobial usage tracking tools.
- Industry-wide commitment to addressing antimicrobial resistance concerns.
Implications and Challenges
As you review the report’s positive outcomes, it’s essential to consider potential challenges that may arise.
- Economic impact: while farmers may save on antibiotic costs, implementing new practices may require initial investments.
- Animal welfare concerns: some critics argue that reducing antibiotic use could lead to untreated infections if not carefully managed.
- Environmental effects: reduced antibiotic use may positively affect soil and water quality, but more research is needed to confirm this.
Future Directions
Industry experts emphasize the importance of ongoing efforts in targeted interventions, knowledge exchange, and developing new targets for further reductions in antibiotic use practices.
- Targeted interventions for high-use farms.
- Investigation of factors driving regional variations in antibiotic use.
- Promotion of knowledge exchange between low-use and high-use farms.
- Wider adoption of practices like Selective Dry Cow Therapy (SDCT).
- Development of new, challenging targets for further reductions by 2030.
Emma Puddy, a Farm Services Specialist at Kingshay, notes that the dairy industry has significantly reduced the use of critical antimicrobials. Since 2020, the number of herds using them has dropped by nearly three-quarters to 3.9%, showcasing substantial progress.
Global Context
Acknowledging the UK’s commendable progress, it’s essential to consider how it compares globally. According to the World Organisation for Animal Health, the UK’s efforts align with a global trend towards improved antibiotic use practices in livestock. However, practices and progress vary significantly between countries, with some nations still struggling to implement effective strategies, such as Selective Dry Cow Therapy, for reducing antibiotic use.
The UK dairy industry’s efforts in responsible antibiotic use serve as a model for sustainable farming practices that prioritize animal welfare and public health. To ensure long-term success and proactively address any unexpected challenges arising from these changes, it is crucial to continue monitoring and conducting research.
