These two pictures show how adequate ventilation in the laying house can produce more desirable conditions for profitable egg production. The photo at left shows how litter can become wet and crusted when there is insufficient ventilation. Studies have shown this is one of the major reasons for dirty eggs. The photo at right was taken in a laying house that was properly ventilated. Notice how the liner is dry and fine.

Birds in this house can be expected to perform much more profitably than when the house is damp and foul smelling. Don't overlook the need for adequate ventilation in dairy calf quarters. In fact, ventilation management can be more critical here than in other livestock buildings. Young animals have little resistance to stress. When pens become damp, disease problems increase.

Also, you'll want to be careful in controlling air flow. If using some natural ventilation, as shown, make certain there are no drafts. Ventilation is an important aspect of producing milk in comfortable surroundings. This is the milk room of the Sprecher Brothers dairy operation in south central Wisconsin.
