Animal welfare management
On the long term, one need to have an idea of the level of welfare in order to improve animal living conditions: welfare assessment On the short term, one should be informed of deviations from normal:
welfare monitoring
deviationwarning management action :
- Collection of more information to understand the causes of the deviation - Isolation of an animal from its group in case of infectious disease
or severe aggressions from other animals
- Remedial action: Medical treatment, adjustment of barn ambiance
…
