Disease Diagnosis & Prevention
Factors that influence disease
•
•
•
•
Stress
Nutrition
Natural Immunity
Environment
Stress
• Stress comes from
– Too hot or cold
– Too little to eat or drink
– Over work
– Emotional (separation from young, abuse, etc)
– Over crowding (peck order, competition, etc)
– Pain or injury
Malnutrition
• Does not always mean starving
• Deficiency of any one or more nutrients
• Deficiencies of vitamins or minerals can
weaken the body’s ability to fight
pathogens
• Lack of calories causes the body to go into
survival mode and shut down nonessential system like immune system
Natural Immunity
• Broken down into innate immunity and
adaptive immunity
– Innate is the generalized immune response to
any pathogen
– Adaptive immunity is the specific – more rapid –
response to a pathogen if re-infected again
• Example – injecting horses with low levels of snake
venom to build up their natural immunity
Environment
• If the environment is chronically dirty, wet,
etc, then more of a chance for infection of
disease.
– Exposes animal to feces (carry pathogens)
– Moisture encourages bacterial & fungal growth
– Causes stress
– Filth encourages vectors like insects
