Ventilation systems for livestock buildings by Dr. Knopf & Oswald

Dear farmers, What can you do if the health of the animals in your barn is not as good as you would like it to be? I asked myself this question around 10 years ago when I noticed the calves in my cattle sheds were not as healthy as they could be. When I started to explore the potential causes, I soon realised that my calves would only stay fit if they had fresh air and were exposed to minimum heat stress. However, simply leaving the door open was not an option. Air had to be guided to the animals, in the right amount and direction. After all, I didn’t want excessive draughts to add to the problem...

What are the consequences of heat stress in dairy cows? H igher early embryonic mortality and reduced fertility. W ithout cooling, the calves have a lower birth weight than with it. C alves that were born at high temperatures will later produce less milk than those born at low temperatures. D isruption of the acid-alkaline balance. M ilk yield can drop from 25 to 40% if the cows are subjected to heat stress during lactation. D eterioration of the milk ingredients. If the temperature is too high, cows will look for a cooler stall. So without cooling in the barn they will be more restless and lie...
