Here we see a very light, open barn, with a big problem: it's too hot! You see the cows are all grouping together to find the coolest place.
The message is clear: watch out for heat stress! Cows like 5 - 15 degrees Celcius.
What we can do here is either improve the ventilation or reduce the sunlight coming in.
What else can we do? You're thoughts are very welcome.
