What should be known about the history of disease in the animal?
Time course of disease on property and animals affected
Where the sick animals are housed
Age class affected
Treatments administered
Population morbidity rate
% of all exposed animals
population mortality rate
% of exposed animals that die
case fatality rate
% of all animals that develop signs and die
how to calculate morbidity rate
sick/#total pop. exposed x100
how to calculate mortality rate
died/#total pop. exposed
How to calculate case fatality
died/#sick
Enzootic/Endemic
Disease that regularly occurs in a particular area/group of animals
Epizootic/Epidemic
Rapid spread of disease to a relatively large portion of population within a short time period
Evaluation of environment
Housing
(design, stocking density, hygiene practices, exposure to wildlife)
Handling and movement
Biosecurity
Mentation
consciousness of animal
1. Alert (awake)
2. Obtunded (response decreased, awake)
3. Stuporous (response is limited)
4. Comatose (response is nonexistent, unconscious)
