They don't. That has never happened before, and likely never will. When you cross a White Shorthorn cow with a Black Angus bull you will get a grey calf (this is how the Murray Grey breed came about, by the way). The same thing occurs if you put a Black Angus bull on a Charolais cow.
Murray Grey and Brahman makes a "Greyman" Murray Grey and Senepol makes a "Senegrey" Murray Grey and Charolais makes a "Chargrey" Realistically, Murray Grey will cross well with most breeds giving exceptional hybrid vigour. The Murray Grey/Limousin is doing very well in the carcase competitons.
Absolutely!! Murray Grey is such a breed that is comprised of only grey cattle, from a light silver grey, to a deep smokey grey colour. Some cattle may also come in a mousey-grey colour. Not only that, but if you cross a Charolais cow with an Angus bull (or a Charolais bull on an Angus cow), you will always get a grey calf. Even a cross on a Simmental cow with a diluter gene to a Angus bull may result in a grey calf with a white face. There are several crosses that can produce a grey calf, so yes, grey cows (and calves, bulls, steers and heifers) do indeed exist.
Yes it is. Square Meaters, a more improved breed from the Murray Grey, are of the Bos primigenius taurus species.
There is no such breed as a "Bromham" cow.
