That all depends on the breed[s] and genetics of that bull calf. You can bull calf birth-weights anywhere from 30 lbs (miniature) to over 100 lbs (large breeds).
Low birth weight is the genetics that a bull passes on to his offspring to be able to be small at birth so that the calf can easily fit through the pelvic opening of his dam. This is important as heifers have small pelvic openings and will have a harder time delivering a calf if the bull they are bred to is not a low birthweight or high calving-ease bull.
That really ultimately depends on the breed of that bull calf.
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 male calf is always known to be heavier than females. Heifer calves (Holstein) are known to have a birth weight of approximately 80 pounds whereas the bull calf can weigh about 90 pounds at birth. This weight can differ between each calf depending on genetics of the parents and growth of the calf while in the womb.
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 steer is not born as a steer because a steer is a castrated bull-calf. In other words, a bull calf is born then castrated (or "steered") a few days or months after birth, or right at weaning, depending on the producer. A bull-calf's birth weight depends on its breeding. He can be as small as 30 lbs (miniature cattle) or as large as over 100 lbs (larger breeds like Chianina, Simmental, or Charolais).
No. A Hereford cow will only give birth to a Hereford-Limousin cross calf if bred to a Limousin bull. Only a Limousin cow can give birth to a Limousin calf--IF she's bred to a Limousin bull. Just like a Hereford cow can only give birth to a Hereford calf if bred to a Hereford bull. Otherwise, she too (referring to the Limousin cow) can give birth to Hereford-Limousin-cross calf if bred to a Hereford bull.
That all depends on the gender of that calf. Bull or heifer or steer?
At birth Charolais bull calves will range from 80-100 lbs, heifers will usually weigh around 60-80 lbs at birth.
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.
A Pied calf may weigh around 100 lbs at birth.
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).
