Input: Input is done by the veterinarian. Data input can be automatic (through xml) or manual. The animal occupation numbers used in the calculation of the indicator are obtained from the governmental database SANITEL. The system allows to link AMU to an individual animal in the farm.
For Walloon dairy cattle, benchmarking (and reporting) is done once a year, based on the average BD100. Consequently, it is done per weight category. ‘Dynamic benchmarking’ is applied: two thresholds are set, recalculated upon every benchmarking and representing the median (P50) and 90th percentile (P90) of the benchmark population. The Flemish (see AB Register) and Walloon cattle farms that harbour the respective categories and have data of sufficient quality are included in the benchmark population.
In addition, the type of antimicrobials used is benchmarked. Three colour codes of antimicrobials are distinguished: yellow, orange and red, the latter including the 3rd/4th gen. cephalosporins and the fluoroquinolones. The percentage of each antimicrobial class and each colour code in the total AMU in each weight category is compared to the mean percentages over all farms. Also the use of intramammary products is benchmarked to the average of all far.
