There's a 50% chance that a cow will give birth to a bull calf. Same with heifers. Therefore the ratio is 1:1 that a cow will be mother to a bull (bull calf) or a future cow (heifer 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.
No. Only a heifer calf twinned to a bull calf will be infertile, not twin heifer calves.
The offspring of a cow is referred to as a calf. A heifer calf is a female calf, a bull calf is an intact male calf, and a steer calf is a castrated male calf (castrated after birth).
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.
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.
Like this:"The farmer had a prized heifer in the cattle shed.""The heifer was bred by the herd bull yesterday.""The cow gave birth to a heifer calf!""Those blasted heifers got out again!!"
"heifer" is a cow that has not borne a calf, or has borne only one calf. Cows are female and the male is therefore a bull.
Yes. The only thing is that this "bull" is actually called a bull calf: the "calf" part of "bull" is dropped after the calf reaches around yearling age (~9 to 10 months of age). A cow has just as much of a chance of giving birth to a bull calf as a heifer calf. The sex or gender of her calf is determined by the sperm of the bull she was bred to, not the cow herself.
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.
