When it comes to poultry house ventilation, it’s vital to remember that the lower the total house static pressure can be kept, the easier and cheaper it will be for fans to move air through the house. While this is vital at all times of the year, it is especially crucial during hot summer months when heat stress can negatively impact birds. In the winter, if target static pressure is not reached additional fans can be turned on. In the summer fans are more easily maxed out.
As part of the Jones-Hamilton Co. line of products, SWASHCOOL-CELL™ benefits from the same level of continuous research and development as all JH products. Over the last year, SWASH™ leaders have diligently worked with producers, integrators and leading names in academia to better understand how SWASHCOOL-CELL™ can benefit users the most in extending the life of evaporative cooling pads.
While the performance of evaporative cooling systems is most crucial during hot months, it’s important to consider what maintenance steps can be taken throughout the year to ensure system performance and pad longevity.
During hot months, evaporative cooling systems are crucial to maintain target temperatures within broiler houses, turkey barns, and sow farms to help producers eliminate the costly effects of heat stress in animals. Heat stress can not only cause welfare challenges and mortality, it also decreases production and reduces profits. Common signs of heat stress are reduced feed intake and growth rates, panting, weakness and watery droppings.
Water quality is one of the biggest driving factors that affect the longevity of cool cell pads. Cleaner water typically means cleaner pads. However, even clean water can lead to damaged pads if pads are not properly maintained. Why does supposedly clean water lead to pad quality issues? It comes down to the composition of the water going through the cool cell system. Understanding what kind of water you have on your farm (mineralogy, alkalinity), the better you are able to develop a routine pad maintenance program to extend the life of your pads.
The detrimental effects of heat stress can be seen across all types of birds: increased mortality in broilers, decreased egg production and quality in layers, and decreased weight in turkeys to name a few. Evaporative cooling and ventilation systems work to create growing environments ideal for bird performance. But what happens when systems aren’t functioning at their target capacity?
While the need for evaporative cooling systems is ending for the season, it’s important to remember that investing time now to properly winterize your system can significantly contribute to optimal functionality in the spring.
Each year, more than $20 million in property losses and between 40 and 50 injuries occur from combine and tractor fires1. In addition to fire risk, a build-up of dust, dry chaff, leaves and other organic material can hinder equipment performance. Routine cleaning and maintenance along with basic operational precautions go a long way in preventing costly fires.
Evaporative cooling pad systems have become an essential part of today’s tunnel-ventilated poultry house cooling system. When properly installed and maintained, they have the potential to decrease the temperature of incoming air by 20°F or more1! However, when not properly maintained, not only can the efficiency and life of this system be dramatically reduced, it may also negatively impact the air speed of tunnel fans.
In hot summer months, heat stress is a constant battle for producers. In broilers, heat stress can result in panting, increased water intake, decreased feed intake and eventually death.1 In swine, heat challenges have increased compared to 30 years ago, with sows generating 55-70% more metabolic heat. Add to that environmental heat, and the potential impact of heat stress rises. In swine, heat stress can cause animals to consume less feed. In addition, decreased fertility and milk production is seen in sows and decreased sperm quality in boars.2
