THIS SUMMER seemed to be hotter and definitely was more humid than previous years. I noticed that this year in particular had many August nights when the humidex barely fell below 25C.In talking to dairy producers, some had the same experience and also noticed their heat stressed cows' milk production as well as reproduction performance fell hard with this rising humidex. While I am confident that milk production recovers once we approach cooler days ahead; dairy reproduction often takes a little more time to bounce back and might be a significant problem for some dairy barns well into the fall. Fortunately, dairy producers can take some post-summer steps to finally get their cows bred.
