Less heat stress for your cows and fewer trips to the barn, with dairy barn ventilation that runs on its own

Your cows stay more comfortable on hot days, barn by barn, day and night. Sensors read the heat and humidity in each barn, the fans speed up or slow down to keep the heat-stress index for cows (THI) at the level you set, and you see every barn on one screen.

The problem

On hot days, the barn can’t wait for you

Heat and humidity together put dairy cows under heat stress. When it climbs, the fans have to react straight away. Run by hand or on a fixed timer, they react late or run when they are not needed, and someone has to be in the barn to change them.

Industry context

THI 68

In high-producing cows, milk loss can start at a daily average THI of about 68.

Extension research now places the start of milk loss in high-producing Holstein cows at a daily average THI of about 68. The long-used threshold was 72.

Outcomes

What you gain

Four things a dairy farm notices first: the herd on hot days, the trips to the barn, the fans and the record.

  • Less heat stress on hot days

    The fans follow the heat stress in each barn and keep it down, without anyone standing in the barn.

  • Fewer trips to the barn

    No need to walk the barns to switch fans by hand. Change the target, or switch a barn to manual, from the screen.

  • Fans only as fast as needed

    On mild days and at night the fans slow down and use less electricity, instead of running flat out on a timer.

  • A record of every hot day

    Temperature, humidity and THI for each barn, with a chart for each reading, to share with your vet or nutritionist.

Industry context

About 0.2 kg

Above a THI of 72, test-day milk yield fell by about 0.2 kg per cow per day for every additional THI unit, in a study of 15,012 Holstein cows on 134 farms in Georgia, USA.

A day on the farm

Fans that follow the heat, from morning to night

Five moments on a hot day, then three screens for any day, all from the Adamakis farm, with a drawing of how the fans follow the heat stress. Scroll, or pick a moment.

What we automate

Everything a barn needs, on one system

Ventilation against heat stress first, then the rest of the barn on the same screen.

  • Barn ventilation

    Fans that speed up only when the cows need it, barn by barn.
  • Your heat-stress target

    Set the target for each barn and change it at any time, or switch a barn to manual.
  • Temperature and humidity sensors

    Live heat and humidity in every barn, turned into one heat-stress figure.
  • Cooling and sprinklers

    Showers or sprinklers for the hottest hours, linked to the same target.
  • Barn lighting

    Long days for the milking herd and a dark rest period, on a clock.
  • Alarms to your phone

    A fan fault or heat stress over your limit raises an alarm, so you know without being in the barn.
  • Energy metering

    Electricity and water metered, so you see what the fans and pumps use.
  • Several barns on one screen

    Every barn on its own tab, and one switch for all of them.
