Ventilation systems
Curtains or fans?
We prefer natural ventilation where possible. This means we will aim to design a building which maximises the air movement when full of cows.
The key aim is to replace the moisture laden air (from respiration), with cool fresh air. The optimum temperature for a dairy cow is around 5C, so this is critical to maximise production and welfare in the building. The cooler the cow, the more she lays down, and the more milk she will produce.
There are two main ways of moving air naturally. These are either:
-
'stack effect' through the ridge or roof, with cool replacement air coming in the sides.
-
also using natural 'wind' blowing through the building, so removing the warm, moist air.
We also advise on renovating existing systems and supplying fans to meet these requirements.
THI is a measure that has been used since the early 1990s. It accounts for the combined effects of environmental temperature and relative humidity and is a useful and easy way to assess the risk of heat stress.
Cow Plan have a dedicated THI calculator page here: https://www.cowplan.com/thi
FANS

CowPlan are proud to work with world-wide market leading manufacturers TopCool, and their European distributor Magdek.
