Welcome to the Netherlands Veterinary Medicines Institute (SDa)

The Netherlands Veterinary Medicines Institute (SDa) is an independent agency established in 2010 to promote responsible drug use in Dutch animal husbandries in general and especially usage of antibiotics.

Available now: SDa-report ‘Usage of antibiotics in agricultural livestock in the Netherlands in 2017’

The Netherlands Veterinary Medicines Institute (SDa) presents its report ‘Usage of Antibiotics in Agricultural Livestock in the Netherlands in 2017 – Trends, benchmarking of livestock farms and veterinarians’ in English, after this report was published in Dutch in June 2018. With this report, the SDa wants to provide insight into the amounts of antibiotics used in the Dutch veal, broiler, turkey, cattle, pig and rabbit farming sectors in 2017.

In 2017, antibiotic use in terms of defined daily doses animal continued to decline in the turkey farming sector (by 23.7%), broiler farming sector (by 7.8%), veal farming sector (by 3.6%) and pig farming sector (by 1.9%). A modest (by 2.2%) increase was observed for the cattle farming sector, considering the low usage in this sector this increase is seen as natural variation over time.

According to the 2017 data, third-choice antibiotics  (fluoroquinolones and third- and fourth-generation cephalosporins) were once again used very sparingly in the monitored livestock sectors.

Considering developments in usage patterns and usage level reductions, the SDa expert panel decided to revise its benchmarking thresholds. The SDa expert panel’s new benchmarking method is based on two different types of thresholds: benchmark thresholds representing acceptable use, and provisional benchmark thresholds for livestock sectors that do not yet have antibiotic usage patterns reflecting acceptable use.

Available now: SDa reports "Usage of antimicrobial drugs in horses and companion animals 2012 - 2014"

The SDa released the reports on usage of antimicrobial drugs in companion animals and horses. The SDa drew up these reports following a request by the Dutch Ministry of Economic Affairs. The survey shows that the usage of antimicrobial drugs in companion animals and horses is low. The DDDADAP in 2014 for companion animals was 2.6 and for horses 0.56. The usage has decreased in the period 2012- 2014 by 17.2% in companion animals and 24% in horses. The usage of third-choice antimicrobial drugs decreased to 0.189 DDDADAP in companion animals and 0.013 DDDADAP in horses over the 3-year period.

SDa determines associations between antimicrobial use and resistance; no justification for benchmarking thresholds

It is with great pleasure that the Netherlands Veterinary Medicines Institute (SDa) presents its report Associations between antimicrobial use and the prevalence of resistant micro-organisms - Is it possible to benchmark livestock farms based on resistance data? This report describes an SDa expert panel analysis of associations between antimicrobial use and the prevalence of resistant micro-organisms. This analysis was performed to find out whether resistance data could serve as the basis for benchmarking thresholds. Read more

Improvement measures linked to the Veterinary Benchmark Indicator

Last December the Netherlands Quality Assurance Body for Veterinarians (SGD) incorporated the Veterinary Benchmark Indicator (VBI) in its regulations. In 2015 the veterinarians will have insight into their own VBI through the various databases. This allows them to compare their prescription patterns of antibiotics with that of colleagues and make improvements where necessary. From 2016 is an obligation applicable to SGD-approved veterinarians with a VBI in the action zone to exert themselves with their farmers to make improvements with the goal to eventually come out of the action zone.

The SDa is positive about this development within the SGD. To break with old prescription patterns is a learning process of both the veterinarian and his livestock farmer. The start of this improvement on the basis of the VBI is an important step in the corridor to restrictive and selective use of antibiotics in animal husbandry.

In February and March the SGD organizes together with SDa  and parties from the Colleges of Stakeholders  information meetings for all the SGD-approved veterinarians about the Veterinary Benchmark Indicator and the associated quality improvement.
