T here needs to be plenty of air-flow movement. However, just blowing hot air won't do it alone. Water is also needed. The cow's heat load increases during summer months due to more intense solar radiation and less air flow movement, as well as higher temperature and humidity. To improve the cow's comfort, it is important to minimize the time cows spend in the holding pen.
M aintaining cool resting areas is critical, as well.
High pressure fogger kits on fans will cool the air and keep cows cool while resting. It's also important to have correct freestall bed dimensions and cow comfort cushions in drylot areas. T here are many ways to design cooling systems on dairies. The most important point to remember is heat stress costs money through decreased production, reproduction losses, cow health problems, mastitis, loss of body condition, high cull rates and even death. That is why implementing these heat abatement improvements can offer a quick payback.
