The climate in the barn is the key!

The choice for the right ventilation solution depends on your specific situation. The type of
barn, its location, dimensions, specific climate conditions , lay-out inside, systems in use etc. ,
all influence the right choice to maximize the best result for your livestock.
Abbi Aerotech helps you to design the right solution that saves you
money and guarantees the best conditions in your dairy barn for animal comfort and for your profit.

Heat Stress: an underestimated issue for dairy cows !

Dairy cows are very sensitive to heat stress, which can cost the dairy farmer over EUR 250,00-EUR 300,00 per cow per year.
Higher producing cows show even more signs of heat stress. There is increasing evidence that relatively low temperatures can lead to depressed feed intakes, lower milk yields, reduced fertility and increased risk of mastitis.
Heat Stress is linked to ambient temperature and to relative humidity.
The temperature-humidity index, or THI, is the common indicator for heat stress.
While the heat stress threshold was previously set at a THI value of 72, new studies show that a THI of 68 already effects the milk production, health and reproduction of high yielding cows.

Simple tips to reduce the negative impacts of heat stress on dairy cattle:

1. Provide adequate shade.
2. Provide cooling with fans.
3. Supply enough fresh and clean water.
4. Modify feed rations to increase energy supply and decrease heat load on the cow.
5. Add sprinklers/soakers and/or misters/foggers when possible.

Abbifan 140-XXP-21
Abbifan 140-XXP-21

The ABBIFAN 140-XXP-21 Dairy cattle fan guarantees extremely low power consumption and perfect control. This very energy-efficient Abbifan is equiped with a directly driven Permanent Magnet motor with built-in electronics. The propeller is fitted directly on the axis of the motor, this replaces the traditional belt drive.

Benefits: fewer wearable components, no maintenance, more quite, more energy-efficient and extremely low power consumption

Also in the milking parlour, additional air movement ensures cooling on hot days. Not only the milker, but also the milking cows take advantage of the additional air movement. The cows stay calm, due to the presence of fewer flies.

The compact and efficient V50 series fans are stepless controllable. They have an air capacity of 4800-8700 m³/h. These fans blow horizontally over the cows and are suitable for an area of ca.30-50 m. Optionally they are equipped with guards.

The PV600 is a ceiling fan for use in the milking parlour. The fan ‘presses’ the air down and ensures optimal air distribution during hot and cold periods.

Cross ventilation provides for fresh outside air in the barn, which significantly improves the barn climate. Furthermore, the cubicles are ventilated longitudinally, which increases the cooling effect for the dairy cattle.

ABBIFAN 140-XXP

Abbifan 140-XXP now equipped with EC DC motor
for extremely low power consumption and an affordable price!
The ABBI-FAN 140-X fan is the best option for the necessary cooling:

  • additional air movement for the animals
  • stimulates heat release
  • maintains milk production levels
  • stimulates feed intake
  • less fly nuisance (blue tongue)
  • dryer cubicles
  • feed stays fresh longer
  • reduces mastitis
  • better conception rate
  • low investment costs

With longitudinal ventilation, the fans are mounted behind each other along the barn’s length.

Mechanical ventilation
Mechanical ventilation

Natural ventilation is a good way to ventilate cattle barns. However, on hot days with temperatures above 20°C, cows start having trouble to lose heat and additional air movement must be provided! This improves the heat release of the animals and thus reduces the risk of heat stress. It is important to start ventilating early; low air velocities already suffice to shift the lead-up to heat stress and while the temperature rises, the air velocity is increased proportionally.

Tunnel ventilation system

Fans can also be placed in the outside wall to draw outside air into the barn through cooling panels. This method, the so-called tunnel ventilation system, can realize temperature reductions of as much as 8 to 12°C! A good cooling system produces an air velocity at animal height of at least 2.5-3.0 m/sec throughout the barn. While the temperature of the air does not drop, the wind chill at this air velocity means that the animals experience a temperature that is 2 to 4°C lower.

Extra cooling
Extra cooling

Besides cooling the barn using Abbi fans, additional cooling is possible through water. A spraying bracket with high-pressure (60-70Bar) spraying nozzles can be mounted to the fan, with a time clock or special regulator ensuring regular water atomisation. The very fine droplets evaporate quickly, lowering the air temperature by some 3 to 5°C.
