The Netherlands' policy to reduce the amount of antibiotic (AB) medication used in livestock production is often hailed as a paragon of achievement. Forged by industry stakeholders and the Royal Netherlands Veterinary Association, it is backed up by tough government regulations and underwritten by the Authority for Veterinary Medicinal Products (SDa), an independent body that sets indicators and parameters for responsible practice.
Its benchmarks are based on scientific evidence and are managed via banded 'traffic light' guidelines that categories and monitor individual farm consumption (daily doses per livestock unit per year) and the amount of medication prescribed by vets. Antibiotic therapies are classified into three distinct groups, which govern how, when and if these medicines can be used with animals.
Introduced in 2011, this sector- wide initiative enabled the Dutch livestock industry to cut its AB use by 70% from 2009 to 2015. The Dutch livestock sector was once one of Europe's highest AB consumers. In 1997 consumption was around 300 tonnes a year, doubling to 600t by 2007- partly explained by the rising livestock numbers and productivity.
But this high usage began to erode consumer confidence and the country's reputation as an efficient, healthy food producer. It is also implicated farmers as a key cause of the country's growing antimicrobial resistance (AMR) problem.
This galvanised the production sector into more proactive disease control across supply chains to reduce dependency on medication where possible. On-farm, the implementation of systematic control measures and industry-wide auditing has delivered year-on-year improvements.
For pigs, usage fell by 38% by 2012 and 2016, the vast majority of which occurred between 2012 and 2013. Recent SDa statistics show after the initial dramatic reductions, overall AB use is still falling but, as was expected, is now stabilising. Animal-day doses for the year show annual decreses between 2015 and 2016 of:
Broiler - 30.1%
Veal Calves - 3%
Dairy - 3.2%
Pigs - 1.9%
However, vets and farmers say the law is just a framework as there's no 'cure all' policy. Speaking during a fact-finding tour to the Netherlands organised by Applied Bacterial Control in October, Erik Boer, a cattle vet with the Vechtdal practice at Heemserveen, said that the Dutch AB regulations had forced a re-evaluation of farm animal care. It had changed mindsets, because vets and farmers now have the same target.
Mr Boer said: "All livestock producers must now demonstrate they have a health plan and they cannot just access medication from any vet, as used to be the case. We ( vets) are audited too, every three to five years, and what we prescribe has to reconcile with farm records. "There must be a traceability and transparency because that's the law, and it's encouraged a one-to-one working relationship between vets and farmers."
If progress is not made against SDa benchmark levels, investigations are likely and actions can be taken, including vets losing their license if AB levels remain high over time.
The SDa traffic light benchmarks levels for AB use include three bands: the target amount (green), a signalling/cautionary rate (yellow) and a high use/alert status (red). Some 94% of pig breeding herds and 90% of finishers are now operating in a green band, compared with only 56% of sows and 77% of finishing pigs in 2012.
The Dutch system is effectively controlling antibiotic use and the costs of medication/kg meat produced are lower. However, for most pig businesses, these savings are being outweighed by the additional administration and professional veterinary inputs required to comply with the law.
Many herds have also increased investment in proactive health strategies, such as vaccination programmes and improved hygiene, bio-security protocols. Since 2010, the Netherlands has been a 120% rise in vaccine sales and a significant increase in clinical testing and on-farm veterinary investigations.
