Due to the common occurrence of environmental stressors worldwide, many studies have investigated the detrimental effects of heat stress on poultry production. It has been shown that heat stress negatively affects the welfare and productivity of broilers and laying hens. However, further research is still needed to improve the knowledge of basic mechanisms associated with the negative effects of heat stress in poultry, as well as to develop effective interventions.
Understanding and controlling environmental conditions is crucial to successful poultry production and welfare. Heat stress is one of the most important environmental stressors challenging poultry production worldwide. The detrimental effects of heat stress on broilers and laying hens range from reduced growth and egg production to decreased poultry and egg quality and safety.
Moreover, the negative impact of heat stress on poultry welfare has recently attracted increasing public awareness and concern. Much information has been published on the effects of heat stress on productivity and immune response in poultry. However, our knowledge of basic mechanisms associated with the reported effects, as well as related to poultry behavior and welfare under heat stress conditions is in fact scarce.
Perry Faulk Sr, Executive Director at Innovative Insulation Inc., gives a practical explanation of the heat stress problem and a practical solution to eliminating heat stress issues in Animal Confinement Barns.
“One challenge to farmers to reducing heat stress economically starts with the architecture of the modern confinement house. The modern Poultry house is a pole barn wrapped in sheet metal. Sheet metal is well known as a superior conductor of Radiant Heat from the sun. The sheet metal’s daytime temperatures during a typical sunny day can exceed 150 degrees. Traditional insulation like fiberglass or foam insulation are conductive insulations and are not well-suited to combat high temperatures in metal buildings due to radiation. The attic temps under the metal roofs and above the insulated drop ceilings of a Poultry house can exceed 150 degrees as well. By the middle of the day the high temperatures in the attic space defeat the insulation above the drop ceiling. If you can eliminate the radiant heat that enters the attic space, you can effectively cool the house by 60 degrees in the summer. We have installed millions of square feet of Ag Barrier, an agricultural radiant barrier that blocks 96% of radiant heat with tremendous results. We have effectively removed up to 60 degrees from these buildings in the summer, reduced propane expenses in the winter and eliminated condensation from under the metal roofs as well.”
“This is Bridgeport’s third year working with Innovative Insulation,” says Jason Whitmore, an agricultural specialist for Bridgeport Corporation in Sioux Falls, Iowa. “We started off using their bubble product. Then the last two years we have seen the value of their Ag Barrier. As of to date we currently have three million square feet installed. We are finding out that Ag Barrier is outperforming the other types of insulation. It is easier to install, half the cost and, and gives much more radiant barrier. Everyone that has used the Ag Barrier loves the results they are seeing. We are getting readings of forty to sixty-degree attic temps cooler in the summer months.”
“In the Midwest most everyone uses a poly barrier to line their ceilings,” Whitmore adds. “We have found that using Ag Barrier does not trap moisture in the ceiling or your roofs, saving you tons of LP. So, with this being said Bridgeport is a proud supporter of Ag Barrier and what it brings to the ag industry, including its lifetime warranty which no other insulation carries.”
Ag Barrier is useful in battling harming radiant heat in multiple Agricultural / Livestock Buildings such as:
Ag Barrier offers a wide range of applications and products for installation in Agricultural and Livestock Buildings. Depending on the structure of your building and the level of benefit required, there is an energy efficient “easy to install” option to consider.
- Wide range of performance options (R-value depends on application)
- Quicker installation results in lower labor costs
- Product does not contain fibers or dust that require respirators or protective garments
- Lowers stress levels in livestock due to lower internal building temperatures (radiant barrier application blocks 96% of radiant heat)
- Reduces the impact of the “black-globe effect” on livestock (reduces the absorption of radiant energy by the animal’s body and results in higher weight gain & reproductively and lower mortality rates).
- Non-toxic / non-carcinogenic.
Ag Barrier’s retail cost of just 13.9 cents a square foot makes Ag Barrier the most economical option for animal confinement insulation.
