Don't know too much about Braunveigh, but all my cattle stand in the shade when it gets hot enough, just like me. And I'm talking about cattle bred for the heat. Doesn't bother me to know they graze all night and chill all day. But I've been through some trials on Gelbveigh and they just didn't hack the heat at all. They got worn out quicker than a rental car. Sold them off and bought Brafords.
they will handle it if they are crossbred with any bos indicus or easier to understand "Brahman influence" or with Italian influence (you could try Romagnola) but I prefer Brahman influnce, more Hybrid Vigor
Are Braunvieh cattle able to handle it? Or will they stand in the shade like Angus and wait till the sun goes down to graze?
