The climate in the shed is the key!

The choice for the right ventilation solution depends on your specific situation. The type of
barn, location of the barn, the sizes, specific climate conditions , lay-out inside, systems in use etc. ,
they all influence the right choice to maximize the best result for your livestock.
Abbi Aerotech helps you 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 Euro 250,00-Euro 300,00 per cow per year.
Higher producing cows exhibit 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 of enough fresh and clean water.
4. Modificate feed rations to increase energy supply and decrease heat load on the cow.
5. Add sprinklers/soakers and/or misters/foggers when possible.

Our dairy farms ventilation and cooling systems

Water is pumped across the pad . The airflow evaporates the water and the air cools down. Temperature can be lowered by 8-15 degrees , depending on local conditions.

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.

The speed of the fan can be regulated by means of a frequency controller, guaranteeing low energy consumption at low speeds.

Abbi-Aerotech provides various options for automatic ventilation control by means of frequency controllers in combination with a DCC-1 or DCC-1SH temperature controller.

 

The DF-Control, (Dairy Frequency control) is a state of the art frequency inverter for 3-phase motors with extra energy efficiency.

Fogging is working with high pressure pumps ( 70 Bar ) and special nozzles , resulting in a fine mist coming in the building. Temperatures can be lowered by 2-5 degrees.
