What climates are Holstein cows suited to?

Answer 1

Mild to cool climates. They aren't as suited for northern climates like that in the north-central part of the Canadian provinces as other cattle are, even though they can (and do) grow a thick winter coat in the winter. A lot of the time they are indoors in that climate, whereas down further south where the snows don't last long and winters are short, they are able to be outside more often. They don't handle hot summers as well though, certainly not those in the subtropical to tropical climates.
