It's a bitch, not as bad as some farther south have it. The humidity adds to it as well. When it stays hot for prolonged periods and the night temps stay high is when it really hurts . Looking at 50%+ drop in production at that point.
50% drop, that is massive. We have had heat waves with day temps over 45C, overnight temps staying over 30C and then back over 40C by 8:30am and I haven't seen a 50% drop in production.
I agree it's the high night temps that really effect cows. We can get 40C plus through the day but if it gets down to 15-20 overnight the cows are usually fine. Those nights that are 20C plus the cows don't actually cool down before the next day and the heat builds up. I've seen them standing under trees at midnight because they were still hot and trying to cool off. Too stupid to realize that isn't going to help at night.
