This question is impossible to answer because there is no reference to location, whether it's of the entire world, of a particular country or a particular state/province within a country.
Breeding dairy cows produces calves which subsequently makes them produce more milk in the next production year. Calves are also raised as replacements (if they are heifers) for the other cows, as these calves have been selected, through the process of sire selection, for giving more milk per year when they mature into cows.
A cow that has a calf at side and suckles that calf, no matter if it's her own or foster calves.
This question is impossible to answer since we have no idea of location where these calves are born, location as in country or state/province.
Calves raised indoors grow faster than those raised outside because they are fed more often. Indoors they have more access to food and are limited to how much they can move around.
Calves, chicken, cow, and... thats it.
Manatees are at least a year old when they have calves.
It's a mark of identification, usually done to calves, to identify certain calves that are to be raised for slaughter, for replacements, as bulls or heifers, etc.
Bear calves could be referred to those calves that have such thick fluffy hair that they look like little bears with four legs; these are often referred to yak calves, Highland calves, or Galloway calves, all of which are born with thick long hair. The term could be a mis-spelling of "bare calves" which may be those calves that are orphaned and are raised in a bottle or bucket by humans.
no because just because
Red deer usually have about 2-3 calves but twins are very rare.
Any cow can have a calf per year, usually cows will be able to breed and produce calves until they are 7-10 years of age.
Depends on the breed. Most calves can gain between 600 and 800 lbs in their first year.
