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.
If you’ve been a SWASH™ customer or follower for a while, you might have noticed some changes in recent weeks. Back in December 2019, Jones-Hamilton Co. acquired FarmLab Innovations, LLC and the SWASH™ line of products. As a part of that transition, we have worked to become a part of the Jones-Hamilton Co. family in a number of ways.
Layer housing has changed dramatically in recent years with the U.S. egg industry adjusting to the demands of companies that have pledged to source only cage-free eggs. Approximately 18-20% of egg production in the U.S. is now cage-free with more producers slated to make the change in five to six years.
The State of the Industry Today
The shift to antibiotic-free broiler production has created a great biosecurity challenge for the broiler industry. Tackling this challenge must begin in the hatchery with efficient cleaning programs that prepare surfaces for the application of registered disinfectants.
While biosecurity has been emphasized on poultry and swine farms for years, attention paid to maintaining secure facilities has increased recently as the nation focused more on animal and human health in the wake of the COVID-19 pandemic. On poultry farms, the primary method of transmission of disease-causing microorganisms is the use of contaminated equipment or worker clothing and footwear. It has long been documented that harmful viruses and bacteria can move from one flock or one farm to the next on trucks, tractors and other equipment.1
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
As producers work to remove moisture from poultry houses, it’s important to understand that temperature plays a critical role in the amount of water air can hold. Humidity describes how much water is in the air; for example, at 100% RH air is at its maximum water holding capacity, while at 90% RH the air can absorb a little more water. Humidity levels of 40% allow for the air to absorb a significant amount of moisture which can then be removed from the house through ventilation.
