6. Environmental Influences on Health
Temperature
Light
Moisture
Being moved
Pollution

7. Endotherm/Ectotherm Endotherms maintain a certain body temperature
Most farm animals
Adjust to heat by panting, sweating or wading into water
Ectotherms body temperature adjusts to their environment
Aquatic animals

8. How light affects animals
Lengthening the day can increase growth and production in some animals.
Chickens

9. How moisture affects animals
Humidity
Moisture in the air
Precipitation
Rainfall, snow, etc

10. Animal Stress
Changing them to get them into pens or barns raises their body temperature. Loading them and hauling them can expose them to wind, heat, cold, and rain
Pollution
It can cause diseases
Pesticide poisoning

11. Disposing of dead animals
Incinerating
Cremating
Composting
Burying
Turning into organic matter
