No. The bull should be separate from the heifer and her calf simply because it's less stress for her and enables her to mother up to her calf without having to be getting after the bull if he tries to interfere with her.
That all depends on the gender of that calf. Bull or heifer or steer?
No.
95 percent of the time they are, they are called Freemartins
The proportion of sexes varies in both directions when the ratios were determined with random numbers. In other words, it's a 50/50 chance that a cow will have a heifer calf or a bull calf.
The offspring of a cow and a bull is called a calf. If the calf is female, she is referred to as a heifer calf. If the calf is male, then he, unless castrated after birth, is called a bull calf. Castrated calves are called steer calves.
A calf is a heifer calf if it's female, a bull calf if it's male.
Bull calf, heifer calf.
You could call it a heifer, or a twin heifer if the sibling is also a heifer, or a freemartin if the heifer's sib is a bull calf.
A calf. If it's a male, it's a bull calf. If it's female, it's a heifer calf. Bull calves become steer calves if they are castrated. A bull calf becomes a bull when he is weaned and reaches one year of age. Bulls are raised and used for breeding cows and heifers. Steers are steers when they are fed and raised for beef. A steer can become an ox if he is trained at a young age to pull carts and wagons. A heifer calf is no longer a heifer calf after she is weaned and becomes one year of age. She is a bred heifer when she is impregnated by a bull at 15 to 18 months of age, then a first-calf heifer when she calves. She becomes a cow after having her second calf.
That all depends on the gender of that calf. Bull or heifer or steer?
A bull calf or a yearling bull. You can also get steer calves, or weaner or feeder steers too, if the bull calf has been castrated.

A calf is a calf from birth to weaning. That calf is no longer a calf after weaning, but a bull (if male and intact), a steer (if castrated) or a heifer (if a female). If the calf is being used for beef, at weaning age it's called a feeder calf. A feeder become stocker steer/heifer/bull when put out on pasture, usually when it reaches around 12 months of age. The calf is called a finisher when it goes into the feedlot to be put on a "hot" ration prior to slaughter, then a slaughter bull/heifer/steer when it is sold to be slaughtered for beef. This part of the equation is primarily reserved for steers. A heifer calf is a female calf from birth. She becomes a weaned heifer when weaned, a heifer after she's gone through the weaning process, then a bred heifer when she gets pregnant for the first time. After she has had her first calf, she is called a first-calf heifer. She can also be considered a cow at this time. She will remain a cow until she dies of natural causes or illness, or is slaughtered for beef. A bull calf is a male (intact) calf from birth. He is referred to as a weanling bull when weaned, then a young bull after being weaned and is not quite a year old. He is referred to a as a yearling bull when he reaches a year old and until he turns 2 years of age. He will then be referred to as a 2-year-old bull when he reaches two. He becomes a Mature bull when he reaches full maturity by the time he's 4 to 5 years old, and remains so until he dies of natural causes or is slaughtered for beef.
This is the wrong question to ask, actually. You should be more concerned about the age that you should put a heifer in with a bull to be bred, not when should a heifer be taken away from a bull. See the related question below, but generally, a heifer should be at least 15 months of age to be bred and be able to grow a calf in her. Now to really answer your question, the bull should be removed after a couple months of being in with the heifer[s].
