Greenleaf dairy farm uses technology to keep cows cool

Local News

GREENLEAF, Wis. (WFRV) — Furnace-like heat in Wisconsin can create a serious problem for dairy farmers. As the temperatures rise, heat stress on high performing dairy cows can cause milk production to drop.

Country Aire Farms uses high powered fans to create a wind tunnel effect throughout their entire barn. A series of small fans mounted above the herd work in conjunction with larger ones that draw outside air into the barn.

“It’s new technology that’s really working well,” says farm co-owner Tom Gerrits “the cows don’t skip a beat in milk production so there’s quite a few benefits from having this tunnel effect.”

An automated sprinkler system also sends down a cool mist for roughly 30 seconds every 12 minutes. Losses from heat stress can start when the combination of air temperature and humidity rise above 68 for the majority of the day.
