Both will work just fine. Neither cross will have the desired heterosis like Hereford on Angus or Hereford on Charolais will.
The average lifespan of a charolais cow is around 15 years.
The natural lifespan of a Holstein cow is typically around 15-20 years. With good care and management, they can sometimes live longer.
A typical Red Angus cow would have an average lifespan of 10 to 15 years of age.
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.
The Droughtmaster is a sub-tropical breed of beef cattle developed in Australia from crossing Zebu-type and British-type cattle (mainly Shorthorn, Hereford and Shorthorn-Devon crosses) cattle during the early 1900s. The lifespan of this breed has not been determined.
Both will work just fine. Neither cross will have the desired heterosis like Hereford on Angus or Hereford on Charolais will.
I assume you are referring to the Shorthorn breed. A red Shorthorn bull bred to a white Shorthorn cow will produce a roan calf. The chance of this happening is 100% in this breed.
Shorthorns are dual purposed animals, they can be used for both diary and beef production. The Milking Shorthorn is the dairy producer.
There is no such breed as a "Bromham" cow.
