ClassyFarm

General

The sample/survey system ClassyFarm, developed by the Istituto Zooprofilattico Sperimentale della Lombardia e Dell'Emilia Romagna (IZSLER) is owned by the Italian Ministry of Health. It started in 2014 for pigs, in 2016 for dairy cattle, and in 2019 poultry farms will be included too. Currently, it is based on a convenience sample of 150-200 pig and dairy farms each. A full integration with the Italian electronic prescription system is planned in 2019.

Data collection

Animal subcategoriesThe distinguished weight categories in pigs are sows/boars, finishers, weaners and sucklers; in dairy cattle cows, heifers and calves are distinguished and in poultry broilers, turkeys and laying hens.

Input: This is the responsibility of the IZLER staff, with assistance of vets and farmers. Data sources of consumption are treatment registries, invoices and prescriptions.

Analysis

The dose-based units of measurement DDDAit and DCDAit are used to calculate respectively the number of days and courses per animal per period (which can be a semester or a year = the time-frame). Each active ingredient is considered as a single treatment, whether it is part of a combination product or not. The main indicator is days of treatment per animal per year; other indicators, such as days per semester and courses per time frames, are provided as additional information. For finishers and the cattle subcategories, weights at treatment are standard estimations set on national level. For the other weight categories, EMA[1] weights are used.

Benchmarking

Farm consumption is compared to the median of all farms at weight group-level and is also classified according to its quartile. Usage of “critical” antimicrobials (fluoroquinolones, 3rd and 4th generation cephalosporins and colistin) are highlighted. The methodology is however currently under review. Particularly, Italian pig production differs substantially from other countries; pigs are slaughtered at 160 – 170 kg and a new age group (i.e. pre-finishers) may be introduced in the next few years.

Reporting

Farmers, vets and farmer groups/associations receive written reports and an oral presentation. Interactive dashboards for pig production are available for authorised veterinary officers, with dashboards for species and user profiles being developed.
