VetStat

General

The Danish VetStat database was established in 2000. It is owned and managed by the Danish Veterinary and Food Administration agency of the Ministry of Environment and Food of Denmark. VetStat was among the first data collection systems to become operational in retrieving detailed data on sales of prescribed drug for animals, hence product packages specific.  Data comprises all animals, although the detailing level of production animals is considerably higher, with data at  herd level, than the equivalent data for horses and pets. 

Data collection

Sub-categories of animal species: of pigs: breeding animals (sows, boars, gilts and sucklers), finishers and weaners (< 30 kg); of cattle: cows, bulls, heifers and steers > 24 months, calves < 12 months and youngster between 12 and 24 months; of sheep/goats: animals < or > 12 months; and of poultry: broilers, layers and breeding stock.
Input: Pharmacies and feed-mills are obliged to report sold amount of drugs, and vets the amount used for production animals in veterinary practice. Livestock owners do not provide data, however, they are obliged to register prescribed medicine usage and store these registrations for five years in the farm. In analysis, the needed number of animals can be obtained from the Central Husbandry Register and represent capacity numbers.

Analysis

The dose-based unit of measurement ADD (animal daily dose; defined per product at the active substance level) is used to calculate the indicator ADD per 100 animals per day. Recently, weighted ADD values have been established, in order to discourage the use of certain types of antibiotics and encourage the use of others. The kg animal at risk of treatment is determined using standard weights defined nationally. The use for companion animals is calculated based on the sales of veterinarian products from pharmacies to veterinarians.

Benchmarking

Benchmarking is currently applied to pigs and cattle. One threshold value is defined per weight category, above which the average ADD/100 animals/day calculated over the last nine months (time frame) may not pass to prevent inhibitory measures becoming in force. This is for pigs referred to as the ‘yellow card scheme’. For cattle a similar system is in place. As the system is online available, farms can follow their position relative to the threshold at any time – hence, there is no defined frequency for the benchmarking.

Reporting

VetStat has an interface for vets with graphs and data, as well as an internet based presentation to farmers. Vets can however apply own benchmarking programmes, the results of which however are secondary to those of the official methodology and results.
