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.

Well...

The regular gestation period for a regular horse is 11 months (compared to humans 9 months)

I don't know if it is different because it is a mini, but i don't believe it's different...

A few weeks before delivering a calf, a cow looks around to find the ideal place to give birth. Depending on how much access she has to woods/trees or shelter, she will choose where she wants to deliver. She may hide the calf in the woods for up to a week before re-joining the herd.

There are actually a lot more than two qualities that crossbreeding in cattle is done, but the main two are increase in carcass quality and characteristics, and greater feed efficiency, both as a result of heterosis from crossbreeding.

Negative three to four months, assuming the cow gets bred two months after calving and the calf is weaned at six months of age. Seriously, a cow is already bred and into her second trimester when her calf is weaned. Cows are not like human females where they can only get pregnant again at least a year or 8 to 12 months post-partum.

Separate the calf and his mother from the herd and put them in a separate pen by themselves for a few weeks. That may teach him to stop stealing milk from other cows and just depend on his dam for milk.

However, you will have to pay attention to his dam. See if she is producing enough milk for him to rely on. If not, then this may force him to have to find other cows to suckle on. Also, some cows are not as strict about having other calves suckle on them as some are: these type of cows should be noted to being potential surrogate dams if you happen to have a calf that needs another mother to take care of it.

If it's the case that the calf's dam isn't producing enough milk, then it may be a wise idea to not find a way to stop the calf from cross suckling. However, if you haven't find the other cows are going down in condition from having an additional calf on them, you will have to consider separating him and his mother from the herd.

It depends on what you need to vaccinate them for. Some calves get a Vitamin A shot a day or two after their born, then a few weeks later get their shots for 9-way Clostridia and Bang's disease and other illnesses, followed by a booster a few weeks later.

Cull them, and send them with a one-way ticket to the slaughterhouse. A few producers who get attached to some of their old cows may let them spend the rest of their days on the ranch in a nice green pasture until they pass on.

Calves are immature bovines that rely on their mother's milk for sustenance and growth, and are typically considered calves between 0 and 205 days of age. Some producers still call young bovines calves even after weaning up until they're around 10 to 12 months of age.

Calves are also the muscular part of a human's lower leg, especially the back part.

It's a cylindrical tube that is about 20" long that starts at the vulva and ends at the cervix.

3 to 6 months. Bottle calves are weaned from the bottle by the time they reach 3 months of age. They can become feeders then or when they reach "weaning" age which, for most calves that have been on their mother's milk, is the age that they are weaned and sold.

Heifers will show their first heat around the age of one year, depending on the heifer.

Several, including trichomoniasis, bovine viral diarrhea, leptospirosis, and others.

The average is about 1 per year. Gestation period is 9 months, then a few months later the cow is fertile again.

Cows do not have "periods." They have what are called Estrous periods or cycles. They last around 21 days long, with heat or estrus lasting around 24 hours.

Cows are already mature, since they are a mature female bovine that has already had at least one calf.

A heifer, on the other hand, reaches sexual maturity at 15 to 20 months of age, and then reaches adulthood at around 3 to 4 years of age. (Most heifers, when they calve at 24 months, are still growing, and will continue to grow for the next 12 months or so while nursing their first calf).

Bulls reach adult maturity at around the same age: 3 to 4 years of age.

When a animal or a pet is in heat that means that your pet or animal is able to reproduce at that time. If you fix your pet this won't happen.

common to when female humans get their period.

Improvement

only most mammalian females are said to be in heat when they want to mate.Heat period is also called estrous and it is part of estrous cycle which is found in female lion tiger cat cattle rat rabbit etc.

No. The best way to tell a cow is pregnant by rectal palpation or blood test. Deciphering whether she's pregnant by her udder is much different than seeing if she's about to give birth. An udder will often get enlarged and the teats will look full (as well as the vulva gets looking loose and floppy and the area around her tail head looks looser too) when she's close to giving birth.
