ASC101 (Chapter 8)

Homeotherm

Warm blooded animal, has body mechanisms to maintain constant body temp

Acclimatization

Process of an animal adapting to its climate over a period of time

Evaporation

Loss of heat through water and water vapor

Normal body temp of dogs

100-102.5

Four methods of heat loss or gain

Radiation, conduction, convection, evaporation

Lower critical temperature

The minimum temperature an animal can tolerate before it must increase its metabolic rate to generate heat.

Conduction

Exchange of heat between objects that are touching

Radiation

Exchange of heat between objects that are not touching

Normal body temp of cattle/cats

101.5

Normal body temp of horses

100

Convection

Exchange of heat through air or water movement

Normal body temp of goats, pigs, and sheep

102.5

Upper critical temperature

The maximum temperature an animal can tolerate before it must increase its metabolic rate to dump heat.

Thermoneutral zone

Range of temperatures where an animal feels comfortable

Poikilotherm

Cold blooded animal, does not have body mechanisms to maintain constant body temp

Normal body temp of chickens
