Without getting caught up in discussions about climate change or changing weather patterns, the reality is that temperatures over the winter months have been higher than normal in recent years. This is leading to reports of greater health issues in cattle housed in sheds with poor ventilation and is also linked in such sheds to animal performance falling well below targets.

A good air flow in sheds is vital for several reasons. A sufficient supply of fresh air will remove gases, bacteria and odours from the atmosphere and also help to regulate an animal’s temperature by removing heat and moisture that they generate. This in turn will keep sheds dry, cooler and cut down on the chances of an environment establishing that bacteria or viruses will prosper in.
