GVET is a voluntary, computerised register for all the treatments in pig farms. It is active since early 2017, and is run by the French Institute for pig and pork Industry (IFIP) in cooperation with The French Agency for Veterinary Medicinal Products, the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) and Isagri, a private software company. 

Data collection

Animal subcategories: Four weight categories are distinguished: sows, fatteners, weaners and sucklers.
Input: Farmers give the input about antibiotic treatments thanks to drop-down lists available in the software: they select the veterinary drug among a standardized list where all medicines are linked with a unique identifier, which allows to know its strength and thus to calculate the weight of active ingredient. Then, farmers either validate the pre-set dosage (according to SPC) or register the actual dosage with one of the pre-set units (g/animal or g/100 kg of body weight for example).  There are also pre-defined lists for the other characteristics of the treatment (dates of administration, duration, reasons of treatment, number of treated animals...). All the input about the denominator is already registered in the same software and in the national database for other purposes: either in the GTE (the technical-economic results of the farm) or in the GTTT (Technical management for breeding herds, where sows are individually identified and linked with their physiological stage and reproductive performances). Thus, this automatic link between different databases (GVET, GTE and GTTT) simplifies the work of the farmers and allows to perform technical, economic and epidemiological impact studies for the measures applied under AMU stewardship.
Vets are supposed to bring technical support to the farmers.  


Different indicators are calculated once a year:
  • For the farmers, results are expressed in ‘number of treatment days’ and ‘number of treatments” per animal per weight group. These two indicators are count-based, using the number of treatment days, the number of treated animals and the population at risk.
  • For national and European purposes (e.g. ESVAC project), the systems also allows to use dose-based technical units (UDD, UCD, DDD and DCD; DDDvet, DCDvet). They are used to calculate two indicators: the number of daily doses per animal and the number of course doses per animal. The weights at treatment of the animals are national standard values, with plans to replace this with real weights at treatment. 


Benchmarking will be performed when a sample of farms deemed large enough to be representative has participated in GVET. Meanwhile, farmers can follow their own evolution of AMU over time. Thus, they can see the impact on AMU of the implementation of a vaccine or biosecurity for example.


Farmers securely access their results on an online interface of Ifip (GT-Direct) which already allows them to consult and analyse their technical and economical results.
