Avoid heat stress in the entire barn – with SMARTCOWTUBES

Much has changed in a dairy barn in Styria (Austria) with approx. 60 dairy cows since the installation of our VETSMARTTUBES ventilation systems. Here’s a comparison:



  • The cows crowded in a corner as soon as temperatures rose above 15 °C (even in spring/autumn!)
  • Result: Reduced feed intake, reduced lying times, performance loss
  • Axial and ceiling fans were inefficient – they did not bring the desired results


System with 4 ventilation tubes:

  • Feeding places: Free stall barn (fresh cow group) and straw bedded pens (dry cows)
  • Cubicles
  • Group area dry cows
  • Group area fresh cows

Our high-precision 3D simulation allows us to do an inch-perfect calculation of the air jets and the airflow for the respective conditions:

  • Every single cubicle receives the exact same air velocity and amount of air at exactly the spot where dairy cows can be cooled most efficiently according to our expert veterinarians.
  • Every feeding place receives fresh air in a way that the cows are cooled, but the fodder at the feed alley remains untouched and therefore does not dry out.
  • Thanks to the precise airflow, the cows scatter evenly in the group lying area, as they have optimal air and climate conditions.
  • Interactions of the tubes can be considered.

The system was installed early in April. Ever since, one can observe longer lying times, a constant feed intake and no building of groups anymore at warm temperatures.

Before and after pictures are the best way to show these results. Click here to see the pictures.

The system also includes an automatic temperature control module, which allows the tubes to work even at temperatures under 10 °C (at lower power). The calculations were specifically adapted to this. Moreover, the system works with highly efficient EC fans for a lower noise level and an optimised power consumption. The system’s total maximum power consumption is 3.2 kW.

We can’t wait to see the first comparative values of the milk yield.

As soon as the hot days of the year are over, we will give an update on the animals’ behaviour under our cooling system.
