There are several reasons why:

1) Bovines would go extinct if cows were not producing calves all the time

2) Cows do not live forever, so they need to produce offspring to keep carrying on their genetics to the next generation.

3) The only way to get good quality beef is to slaughter calves from cows that have been raised to a slaughter age between 18 and 24 months.

4) Cows cannot continue to produce milk if they do not have a calf once a year. In order to produce milk, a cow must give birth to a calf.

5) It's a natural thing for cows to do, just like in all animals in this big ol' world (including humans). It's all a part of the Life and Death cycle.

only a tiny little bit the rest are unnatural chemicals made by man

Gestation period is the time, from the point of fertilization, that the embryo divides and replicates into a fetus, which further grows in the uterus--as a baby calf--until it is too large to grow any more in the uterus and thus needs to be born.

Gestation is a very important part of the conception, growth and development of the calf because the outside world is a very harsh and cruel one that a very fragile, tiny embryo/fetus would otherwise perish in. The cow has the tools (a.k.a the womb or uterus) that helps in not only the protection, warmth, and stable environment that the little baby calf needs, but also in the constant supply of nutrients and waste expulsion through the umbilical cord and the placenta. Without all these tools, this little calf would simply die off and be absorbed into the cow's system. Ultimately, gestation is far more important for calves than cows, even though, in cows, it's a means of producing offspring and spreading their genetics around to future generations.

The gestation period is also a way for producers to tell which cows require more maintenance and labour to keep during their pregnancy and which require less. It's also a means of determining mothering ability, milking ability, calving ease, calf longevity, fertility, and ability to gain weight with suckling a calf, before her next pregnancy.

It should only be a matter of a couple hours.

Bulls don't go through gestation periods: cows and heifers that have been bred do. Bulls are intact male bovines that are used to breed cows, and can settle as many as 50 cows in one breeding season. Cows are mature female bovines that are capable of having a calf, and typically the definition of cows means that they have already had a calf. Heifers are females that have never given birth to a calf. So, if you asked your question with cows or heifers in it instead of bulls, you would get a better answer. :)

In the "wild" (really, there are no truly wild cattle in the world), or those raised on range and pasture all their lives, a cow may be able to live until she is around 15 years of age. Some females may go longer, others less, depending on their productivity and ability to "cull themselves out" of a herd.

Brahmans are known for their great mothering ability, yes.

Get it in a warm dry place after it has been born and after you have ensured the calf is alive. Then bottle feed it with colostrum for the first 24 to 36 hours, then slowly wean it of colostrum to replace it with milk replacer. Do this only if the newborn calf is an orphan and you cannot find a serrogate mother to accept it.

Depends on the breed and the birth weight of the calf. Some cows can stand as tall as only 2 feet at the shoulder; some are as big as 3.5 feet at the shoulder.

That all depends on the age, weight, condition and type (beef or dairy) of calf. Are you referring to baby bottle calves, or feeder beef calves that have been weaned? It is that kind of information that is needed to be able to answer this question.

A bottle calf can be sold for as little as $10, and a beef calf that has been weaned that weighs around 600 lbs may go for as much as $500 to $800 (sometimes more) depending on current prices.

Anywhere from about a month to she already had the foal 5 minutes ago.

Some mares will have a large but not tight udder for over a month...first foal mares may not have a bag until after they foal.

Milk color is a better indicator of how soon the mare will foal and generally once the milk turns white she will foal within days. That being said, some mares will be consistent in their pre-foaling behavior every year and others will not.

The name of a baby cow is a calf (plural: calves)

For dairy operations, they should be separated when the calf is a day or two old. These calves must be fed milk replacer in a bottle or bucket until they are around 3 months of age when they can be weaned and be on a diet of hay and grain. Dairy bull calves often don't have the luxury of meeting up with their mothers again. However, dairy heifers that are going into milk production may, though they don't have as much of a social structure between each other as beef cows do, since they spend most of their time in a stall.

For beef operations, calves should be weaned when they are between 6 and 10 months old. If the cow is getting too thin before the calf is 6 months old or there is not enough feed to have the cows feed their calves to 6 months, early weaning at 3 or 4 months of age may be neccessary. Calves can either be separated by fence, or by taking them away to another pasture. But if calves are weaned with a EasyWean nose ring, they aren't separated from their mothers but instead allows the nose ring to make their mothers wean them. Heifers in these kind of herds never really leave their mothers nor sisters and aunts, but stay with them for life. Those heifers that are not good enough to stay on the farm, though, have to be separated from their dams. Steers, on the other hand, and most bull calves, are separated from their mothers by the time they are around 6 to 10 months of age.

Most calves are weaned by this time, thus may be still called calves, but others may call them heifers (if female), bulls (if intact) or steers (if castrated).

A cow's uterus is an irregular shape, but it certainly does not look like a woman's uterus, which is triangle-shaped. A cow's uterus is divided into two "horns" which divide out in a V-shape if looking at the uterus from above.

In most cows, the chance of a cow having twins is 0.1%. However, there are occasionally some cows that will calve twins all every season. Most cows, though, give birth to only one calf per calving season.

sorry my Q was wrong ans is what doea a girl has three and a cow has 4

No, they have hair, though it can be considered fur. Fur is generally more finer and softer than hair, and cattle don't have fine fur; they have hair.

Yes, most definitely. Cows are not like mares, does or ewes where they will only show signs of estrus in the presence of an intact male of their own species, a cow or heifer will come into heat regardless if there's a bull present or not.

Many, many products come from cows. Directly speaking, beef, milk, leather, manure and other cattle (via sexual reproduction) come from cows. Indirectly, things like clothes, shoes, boots, gloves, horse tack, pharmaceuticals, paint brushes, insulation, paint, gum, gummy candies, shampoo, soaps, ice cream, yogurt, baked goods, the list goes on comes from a cow.

The calf comes from the uterus (or womb) of the cow, where it had been "living" and developing since it was conceived over 285 days ago. It is pushed through the birth canal (also called the vagina) through uterine contractions provided by the cow in the process called parturition or "giving birth."

A rhetorical question. Cows and bulls differ in that bulls do not make milk. That's your answer.

No. Cows can (and commonly do) lactate without being pregnant. A cow can be open (or not pregnant) for several years and keep giving milk...as long as she is being milked out regularly. If not, then she dries up and then you will need to breed her to get her producing milk again.

Dairy cows are bred so that they keep producing offspring or replacements for the dairy herd, mainly because the culling rate (or turn-over rate, if you want to think of it that way) is quite high--some farms have a cow turn-over rate of around 30 to 40%, depending on management criteria. As such, replacement heifers are needed pretty well all the time to replace those cows that get culled.

It would be the same term for a bottle-fed or bucket-fed calf, or a hand-raised calf. Essentially it's a calf that is raised by humans instead of from its "biological mother" being a cow.
