The effects of high environmental temperature on dairy cows include the following except

The correct option is "high feed intake." High environmental temperature has several negative effects on dairy cows, including fever, high water intake, low milk production, and restlessness. Heat stress caused by high temperatures can lead to decreased milk yield, reduced fertility, and increased susceptibility to diseases. In response to high temperatures, cows may also reduce their feed intake, which can further decrease milk production and cause weight loss. Therefore, high feed intake is not an effect of high environmental temperature on dairy cows.
