Yes, if that's what it takes to save the calf!
A Black Angus calf at 4 months old typically weighs around 400-500 pounds. This can vary based on factors like genetics, diet, and overall health of the calf.
No. A Hereford already has a white face, so no use calling Herefords "baldy herefords." The genes for a white face is dominant to that of a coloured face like black, red, tan, etc. So, if you bred an Angus bull with a Hereford cow you will ultimately and always get a calf that is black with a white face. The only time you will get a small (16%) chance of getting a purely black calf is if you breed an F1 black baldy cow with an F1 black baldy bull. Another 16% will give you an all black calf that is horned (from the genes of the calf's grandsire or granddam, which ever was a Hereford (non-polled)). However, if you breed an Angus bull to an F1 black baldy cow, you will have a 50% chance of getting a pure-black calf.
Genetics. The genes in the momma cow combine with the genes from the calf's sire to create a calf with either the same colouration of the cow or not. What breed the calf's sire matters to. For instance, a Hereford sire bred to an Angus cow results in a black-baldy calf. Or, an Angus cow that has a recessive gene for Red colour and is bred to either a Red Angus bull or a Black Angus bull also with a heterozygous gene for the red gene can most likely produce a red calf. And the examples go on.
You can either buy one--off a local producer who sells such calves or from your local salebarn--or you can get one yourself by breeding an Angus cow with a Hereford bull (or a Hereford cow with an Angus bull). Even breeding a modern-type Simmental cow with an Angus bull (or vice versa) will get you a black-baldy calf.
That all depends on the breed[s] of either the sire and the dam.Basically, though, if the black bull is Angus, and the white cow is Charolais, then the calf that results will come out grey.
Angus or Black Angus are black. Red Angus are red.
The average weight of a 7-month-old Black Angus calf typically ranges from 500 to 700 pounds, depending on factors such as genetics, diet, and overall health. Males usually weigh more than females during this stage. Proper nutrition and management practices can significantly influence their growth rates.
Growth rate or ADG (Average Daily Gain) depends on what the calf is fed, how much milk it gets from its dam, and its genetics. ADG ranges from 1.5 to 3.0 lb/day.
That cross does NOT produce a blue calf. This cross will give a GREY or smokey-grey calf, never blue. The resulting cross would simply be called a Char-Angus cross or Angus-Char or Angus-Charolais cross.
A black Angus is a type of black, hornless cattle from Scotland.
The length of lactation in an Angus cow is for as long as she has her calf on her, which is around 6 to 10 months.
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.
