Cattle Reproduction
Knowing reproduction of cattle is important to the herd, no matter how big or small it is. Cattle reproduction involves breeding, genetics pregnancy, calving, care of the young calf and weaning, all of which is involved in the reproduction of cattle. Questions about everything involving in cattle reproduction, including a little on lactation, can be asked and answered here.

What is the gestation length of a miniature 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.
What are two improved crossbreds of cattle?
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.
A bull is a bovine and a mare is a horse. Your question makes no sense.
Another Answer:It depends on what part of the word "dangerous" you are referring to. Are you asking is it dangerous for the mare or dangerous for the bull?
From the gist that I'm getting from the question asked, I have to say yes, especially for the bull, as he could get injured if he keeps trying to breed her. Please do these two animals a favour by completely separating them from each other.
Additionally, though I have no idea what kind of other animals you have on your farm, if you have the bull because you only have one or two cows, do yourself (and even the mare) a favour by considering selling him. That bull is most likely attempting to mount the mare because he is sexually frustrated that he doesn't have a large number of cows to breed with. One bull can be used to cover from 10 to 50 cows or heifers in one breeding season: this means that cattle are polygamous, not mono- nor bigamous. If he isn't given the opportunity to release his pent-up sexual energy by being with his girls for a few months to breed as many of them as he can in that period, then he will find other ways to release his frustration and attempt to breed other animals like your mare, or break out of his enclosure and go in search of other cows that are requesting his services.
Bulls can also be very dangerous, and cost more (especially in feed and mineral) to keep than it costs to keep a couple of cows around and breed them via AI. (AI is an alternative and completely harmless to having a bull around, especially if you only have one or two cows around.) It's also not worth anything by keeping a bull around as a "pet" (bulls are actually the worst kind of pet you can have) if you have no cows to speak of and if he's causing more trouble than he's worth. If that is the case, then consider selling him to someone who can make better use of him.
If you can't or don't want to get rid of the bull for whatever reason you have, be it that you're keeping him because you are some sort of farm sanctuary, or you cannot get any local artificial insemination technicians out to provide regular breeding services to your cow[s] (or don't wish to have your cows serviced via AI because you believe it "cruel" and "unnatural," the former which is not and the latter is), then keep the bull and your horse separate from each other permanently. I would also strongly recommend you consider the future of this bull from what I mentioned to you above if he is causing more trouble than just trying to perform interspecies coitus.
How many months after weaning her first calf will a cow get pregnant?
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.
How do you stop a calf from cross sucking?
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.
When should you give cows shots?
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.
What can you do for an older beef cow not producing enough milk for calf?
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.
How young do calves go in heat?
CALVES SHOULD NOT GET BRED. Ever!! A calf is a young bovine that has not reached maturity, and is not weaned or has just been weaned from her mother. A calf becomes a heifer after she has been weaned (or is no longer dependent on her dam), and that heifer will be bred when she is 15 months of age. By the time she is of that age, she is no longer a calf.
However, there are always an exception to every rule!! A calf can indeed get bred, but as mentioned above, that doesn't mean it should get bred. Big difference! Calves that come from a highly fertile herd that are often run with the herd bull or other bull calves that are also reaching puberty, can reach puberty one to two, occasionally three, months before they are weaned (assuming that most calves are weaned at around 6 months of age). If that's the case, then there's a likely chance that the heifer calves will get bred by the bull or other bull calves and even carry a calf to full term. This doesn't happen all the time, it's more occasional or rare than common, but it does happen. Sometimes a heifer calf will carry a calf to full term and birth it without any assistance, much to the surprise of the producer. Other times though, a heifer's pelvic opening may be too small and a calving heifer will need assistance calving, either by pulling or by caesarean section.
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.
When does gestation start for cows?
The stages of gestation are divided into three periods, all around 3 months and 5 days each:
- First Trimester - Day 0 to Day 94
- Second Trimester - Day 95 to day 189
- Third Trimester - Day 190 to day 285
A bovine is another word for domesticated cattle of the species Bos primigenius, subspecies taurus(European/British-type cattle) and B. indicus(tropical/desert-type cattle). Colloquially, they are also called "cows."
Another Answer:
Unlike the name for all other farm animals, English has no widely-known word for (gender-unspecified) "bovine animal." ("Bovine" is really an adjective.) "Horse" can refer to a mare or a stallion, "sheep" to a ewe or ram, etc. "Cattle" comes the closest, but is strictly plural. "Cow" implies the female, ""bull" the male, and "steer" and "ox" neutered/castrated bulls.
What does a cow vagina look like?
It's a cylindrical tube that is about 20" long that starts at the vulva and ends at the cervix.
When can a calf start eating grain?
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.
What do you call a cow in heat?
Heifers will show their first heat around the age of one year, depending on the heifer.
What sexually transmitted diseases affect cattle?
Several, including trichomoniasis, bovine viral diarrhea, leptospirosis, and others.
How many calves do cows have a year?
The average is about 1 per year. Gestation period is 9 months, then a few months later the cow is fertile again.
What is the length of a cows period?
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.
What is the age of maturity for a cow?
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.
What does it mean when a heifer or cow comes in to heat?
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.
How can you see your cow is pregnant?
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.
What should you do if a cow won't stay with her calf?
Giver her a dose of oxytocin to give her a kick-start to start lactating. Also give the calf a bottle of colostrum (or tube him if he's too weak to start suckling) immediately after he's born. If the cow is still not lactating, then you need to start bottle-feeding the calf regularly until either the cow starts producing enough milk for the calf, or until you have to wean him from the bottle.
If they are drinking milk from their mother, next to nothing, they will only begin to eat forage (hay and grain) at approximately 5 months (this is when they will begin to really need it). At this point in time a 40 kg bag of grain will last over a month. However, if you need to feed the calf milk replacer, it runs about 40 bucks a bag and could last under a month.
They should be weaned at about 10 months (if on milk replacer than about 6 months to save money), at this time they will need more grain. Then a 40 kg bag of grain may last a month to 3 weeks (depending on what kind you are feeding you are probably looking at about 10-15 bucks per bag).
Babies are easy to care for and don't cost too much, they start to eat more at about 10 months old, it is best to research what feeds you feed them before you start to feed them, protein is important (keep that in mind), a feed that has about 14% protein is good and usually only costs 12 dollars per bag.
When should beef cows produce milk?
Prior to having the calf, the milk begins to form or snythesize in the cow's mammary glands. Prolactin, adrenal cortical homones and placental lactogen are what are responsible for the beginning of milk synthesis in the cow's udder. All of these hormones increase rapidly right before parturition or birth, which induces greater milk synthesis. After delivery, the hormone (oxytocin) stimulates "milk letdown" from the action of the suckling calf.
Cows will produce milk for up to 10 months normally. The calf suckling action releases more oxytocin from the hypothalamus in the brain which stimlates more milk production. When the calf takes in less milk, the production will slow.
What do you do if your cow has placenta out before the blister at calving?
It depends on a lot of factors, including whether your cow is a first-calver or one that has calved before, or if she has accepted her calf right away or not. Often heifers that have given birth to their first calf won't pass the placenta until 2 to 12 hours later. Suckling often triggers uterine contractions to start shedding the placenta. If she is slow to accept her calf, or doesn't have a calf nursing on her, then the process of her cleaning out will be a bit slower. Twins can cause a retained placenta; so can anything that causes a calf to come early (heat stress, inflammation of the placenta from some infectious disease), nutritional deficiency, lack of exercise before calving, or even if the cow is overweight.
So, with that in mind, what I would do, if I were you, is just leave her be. Make sure she gets lots of exercise, as this will often help her clean out her placental membranes. Keep an eye on her in case she gets ill on you all of a sudden, but really, it's actually rare for a cow to get an infection from having a retained placenta. But if she does, then get some antibiotics in her straight away. Injections of Oxytocin can help the uterus to shrink up and shed the placenta, but keep in mind this is only helpful after the first 48 hours (from the time she birthed to 48 hours later). DO NOT go in to get the placenta out yourself nor even ask a vet to do it, as the membranes should be let to slough off on their own. Even the vet will tell you that, because careful removal can still cause damage to the uterus, and small pieces of that membrane are often invariably left inside, which may cause problems later.
If your cow does not develop a serious infection following a retained placenta (and most cows don't), she will eventually clear the temporary infection and inflammation on her own, and will have normal fertility. But she will have normal fertility if you don't have her bred at least 60 days after calving.
