Introduction

Sheep, cattle, and other livestock have techniques to protect themselves against changes in temperature. Most animals have a hide or fleece to provide warmth and protection against cold and wet conditions. In summer animals sweat to increase heat loss through evaporation and may seek out natural shade sources such as trees or stay close to water.

Animal producers and owners also have many ways of managing animals to provide proper care and shelter. Barns and shelters can protect animals from cold, rain, and snow in the winter. Barns can also provide shade in hot summer months. Sometimes, animal producers will use misting systems to help cool animals.

Sheep producers are able to shear their animals to help regulate body temperature. Does it make sense to shear a sheep right before winter? In this activity you will explore the effect of insulation on maintaining body temperature.
