What Angus cow? There are many different cows from different ranches, all with different reg. #'s. Please be more specific! Check out the American Angus Association website for the Angus cow you are looking for.
Angus is not any part of a cow. Angus is a BREED of "cow" or bovine, specified by the colouration and genetics that determine whether an Angus cow is purebred or not. Angus cattle are always all black, unlike other breeds that have followed the black trend like Simmental, Gelbvieh, Maine Anjou, Charolais, Limousin and Salers who, traditionally are not black. Please see the related links below for more info.
A healthy, fully mature Angus cow can weigh anywhere from 1200-1600 lbs.
A cow is a cow. Milk is milk. Quantity and butterfat content will vary with each breed. Black angus is a breed. Drink Up!
An Angus cow is exactly the same as a chicken or a flying pig that meows.
naturally born.
An Angus cow can weigh anywhere from 950 lbs to 1800 lbs, more or less, but have an average weight of around 1500 lbs.
An Angus cow only produces around 20 to 30 lb of milk per day.
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.
Maybe the farmer or rancher wanted to keep that particular cow along with his black ones. That does happen, you know: a large herd of commercial Black Angus cattle may include a couple Red Angus or Hereford cattle in it.
