A negative pressure poultry house operates effectively during most of the year, but wintertime conditions can pose a problem. The large deviation between indoor and outdoor conditions causes the system and the grower to work harder to maintain the optimal environment for the birds. This article reviews optimizing fan winterization in poultry houses and the impact it has in the field. The grower must winterize the building to prevent unwanted cold, damp air from entering.

The large deviation between indoor and outdoor conditions in the wintertime causes the system and the farmer to work harder to maintain optimal environment for the pigs. When a fan turns on to bring air into the barn, most of the air should be brought through designated inlets. However, if the barn is not properly sealed, air can enter the building through any opening which leads to cold air entering directly into the barn without properly mixing. The farmer must winterize the building to prevent unwanted cold, damp air from entering.

A properly designed environmental control system is a high priority in today’s poultry houses. The system must maintain the correct temperature, humidity, and air velocity while minimizing noxious gases to create optimum conditions and results. Keep in mind, the optimal settings for these parameters will change throughout a bird’s life.

It's time to start thinking about and preparing for cold weather ventilation. Even though minimum / transition ventilation is important year round, it is even more important to get things right during cold weather to assure the welfare of the chicken and control of litter conditions. It is not as critical when the outside air is warm and the inside air falls to the floor. However, when the outside air begins to get cold and damp, it is very important to keep the air off the floor and directed into the peak of the house.

Retrofit projects allow producers to use existing structures to add new components. As production costs continue to rise, we need to do all we can to help minimize extra labor expenses. University articles have listed air mixing as one of the most important ways to reduce heating costs. One of the easiest ways to do this is to have the right size fan and inlets as well as inlets that do not leak air back into the attic.

A proper circulation fan system gently moves air across the litter while ensuring chickens or turkeys are not being chilled. A circulation stir fan system is used not only to break up temperature stratification and create more uniform conditions from one end of a poultry house to the other - but just as importantly - stir fans are used to increase the level of air movement over the litter to aid in moisture removal. Proper litter management will result in better environment for the birds and ultimately better health and performance.

Wean healthier litters and protect your sows with the right flooring. A farrowing floor should be cool for the sow and warm for the little pigs. Cast iron under the sow is cool and Filter-Eeze polypropylene in the creep area is warm. The cast iron provides excellent traction for the sow, is durable yet comfortable, minimizes possible teat and foot damage, helps prevent abrasions, and cleans well. The plastic in the creep area is non-conductive and does not rob body heat from little pigs.

Ideal broiler flock performance is greatly affected by correct ventilation management. It is important to note not all poultry sidewall inlets are created equal - some poultry sidewall inlets are better at directing air across the ceiling than others. As the poultry industry is evolving, house design and construction are evolving too. Ideal air mixing in super houses is more difficult to achieve in wider super houses (larger than 60 ft. wide) without the proper equipment. European Sidewall Inlets have a curved blade and recessed design that is the ideal design to achieve complete air mixing in poultry houses.

Since technology is always evolving, swine barns should too. Think back to barns built 30 years ago. The production practices, barn construction, ventilation practices, and equipment to service the animals have all evolved drastically. The driving factor to these changes is usually to gain production efficiencies, ventilation efficiencies, and provide an overall healthier environment for production animals that reside in barns.

Achieving optimal performance from a broiler flock depends on executing the ventilation as correctly and efficiently as possible. During minimum ventilation periods, producers are concerned about moisture, litter condition, keeping birds warm, and air quality. The more control producers have over air quality, air temperature, and energy usage the more control they will have over their paycheck at end of grow-out.

Inlets will not perform without static pressure and you cannot have proper static pressure if you have air leaks. Most managers overlook the fact that static pressure is affected by air leakage. Remember, you are trying to pull incoming air in through engineered openings, not through random leaks in the building. Cold air entering through cracks, curtains, or inlets is heavier than the inside warm air. If it does not shoot into the room with sufficient speed at ceiling height, this incoming cold air will immediately fall downward along the sidewalls and endwalls, resulting in pigs being chilled.
