Document Summary
Benefits of sickness behaviour: sickness behaviour is proposed to constitute ad adaptive strategy involving energy saving measures such as. General disinterest in pleasurable activates, social behaviours and interactions. Energy normally used for growth and reproduction will instead be used for the energetically demanding metabolic activity of the immune system. Assessment of animal welfare at the group level. What to assess: measures of the environment and resources: welfare inputs resource-based measures, measures of the animal"s responses: welfare outputs outcome-based measures. Animal/ genetic, early life experiences: outputs. Real-world problem: group assessment living in large groups. Assessment on group level: choosing welfare indicators. Practicability: time constraints, expenses, handling of animals, observation periods. Validity: meaningfulness of the parameter, test has to be validated using another, scientifically accepted measurement. Health and welfare monitoring impact assessment of interventions: voluntary certification schemes, legislation, codes of practice, advisory preventive medicine. Perceive evaluate act revaluate: benchmarking system. Giving points of reference for; animal-based parameters, production performance: management system.
