When a cow is calving is it normal for only one leg to come out at a time?
No! It is normal for BOTH legs to come out at the same time, not one at a time. One at a time has potential for the calf's elbows to lock up, making it difficult for the cow to pass the calf. When that happens you need to go into the cow, push the calf back and then pull the leg that is back too much to the full extension, or as full extension as the other leg is positioned. Then you can pull the calf out.
Why do cows stand while calving?
It depends on the difficulty of the birth. For some cows, the calving is really easy and they can easily push out the calf while standing. For others, the pain can be a bit too much and they have to lay down to calve. It also depends on the individual cow: some like to stand to give birth (or can), others prefer to lay down on their sides.
How long does it take for a cow or heifer to give birth?
It depends on the age of that cow or heifer, what position the calf is in when it enters the birth canal, and what size the calf is. Some may even say that it also depends on the sex of the calf as well. It should only take a few hours or more for the calf to start to emerge during the early stages of labour, being presentation of the water sac and the calf's front hooves. Once the water sac emerges, it usually takes from a half hour to an hour for the calf to be expelled. Most cows that have had experience will only take 10 to 30 minutes to "spit" the calf out. Cows that have been bred to a bull that does not have the genetics for easy calving tend take longer due to the fact that they have a bigger calf to push out. Heifers, on the other hand, may take several hours to give birth because of their smaller pelvic opening. Heifers that have not been bred to a calving-ease bull tend to end up with more problems, and will take longer to calve out. If a calf is not in the proper position it will also take longer, and may end up needing help from a vet or the rancher/farmer to pull the calf out and ensure the cow/heifer and calf's survival. As far as the sex of the calf is concerned, there are some claims that if a cow retains a calf for longer or takes longer to give birth the calf's a bull calf; the opposite is true if it's a heifer. Not sure if this has any scientific merit, or if it's just some old wive's tales.

When should a farmer help a cow give birth?
When she is obviously having troubles pushing out her calf, or, she's not progressing any further in her efforts to push the calf out of her after some time.
What do you do when a calf died in a cows uterus?
This depends on how long the calf has been dead for. If it's only been for one or two days, the calf should be pulled out. However this can be a very gruesome task, and is definitely not for those that are faint-hearted nor those who have weak stomachs. The reason I say this is because often the calf that is inside the cow has already undergone rigour mortis (or the energy in the calf's muscles are used up to the point where it is very stiff), making the calf far less flexible than it would be if it where alive or died just minutes or a couple hours ago. When rigour mortis sets in (which often takes around 4 or 5 hours after death, depending on the size of the animal), it makes it extremely hard to pull the calf out because its ligaments are so stiff. To make matters worse, the amniotic fluids that would otherwise make the uterine and vaginal tracts lubricated, have been excreted, making the uterus quite dry, not to mention pose a LOT of pain for the cow when she tries to push the calf out. But the sooner you get the calf out, the better.So, here's the gruesome part (for those of you who get offended easily, STOP READING NOW). A saw has to be applied to the calf to cut off it's head, and even possibly its legs, to make it easier for the dead calf to exit the uterine tract. The calf is already dead, so it won't feel anything as the vet or you saw the head off, plus the blood from the calf makes the uterus a little more lubricated and a little easier to pull out. Often the head has to be taken off because it just will probably be too swollen to fit through the birth canal, and the front feet should be left intact to allow the calving chains to be applied and to help pull the calf out. Of course the cow will be in a lot of pain as she tries to help push it out.A C-section could be extremely dangerous to the cow because it could invite infection to the cow, especially if the calf has started to rot or decompose in the cow. Toxins will more than likely get into the rest of the cow's system and kill her. For cows that have had a dead calf in them for the last 3 or 4 days, it is best to put her down. If the calf is removed from her, she will undergo so much shock and so much toxins that were being held in her uterine tract will be let loose that she will die within 5 to 20 minutes after the dead calf is removed.That's why it is IMPERATIVE and CRUCIAL that you ALWAYS keep an eye on ANY calving cows. Don't leave a cow for a day or two if you've seen her trying to push but has had no success. Check on her in an hour or two to see how she's progressed, NOT after a few days!!! If you suspect a cow hasn't calved after a certain period of time, get the vet out IMMEDIATELY. If you can't get the vet out right away, get her in the headcatch and reach inside to see why the calf isn't coming through, and try to correct the problem yourself. Get the calving chains on the calf once you've positioned it correctly and start pulling. Do not wait for a day or two to see how she's progressed: often by the time you eventually decide to get the calf out (a day or two later), you will have already lost the calf.

A cow is having trouble giving birth what to do?
Get her in a head gate, preferably one in a calving pen, if you have one, or a headgate with the squeeze chute side settings set as wide as possible. Next you'll have to glove up (use shoulder-length gloves if you a bit squeemish of going in bare-handed) and go inside the cow's vagina into her uterus to see if the calf is not presented normally. A dystocia calf may have one or two legs turned back, his head turned back, he may be backwards (a breach), or there may be twins that are causing trouble. If it's a simple problem like head turned back or a foot turned back, it shouldn't be too hard to get him in proper position. But you have to be careful about how you get him in position so you don't tear the uterine wall by accident. With feet or head, you have to push the calf back away from the birth canal (against the cow's contractions). With the head malpresentation, reach in and cup your hand around the calf's nose and turn his head so that it's facing towards you (or the rear of the cow). With the leg, cup your hand around the calf's hoof and pull the leg up until it is parallel with the calf's neck. With more difficult presentations like a breach or twins, you may have to call a vet. Other dystocia factors that make it difficult for a cow (or a first-calf heifer) to calve out is that the calf may be too big. A vet is mandatory in this case, as a C-section will have to be done. Make sure you catch the problem early and don't wait for 24 hours after you see the signs of a cow having problem calving out. If you see a cow that is having problems calving, first wait for 2 to 4 hours, and if nothing has progressed, then phone the vet. If you wait for 24 hours or more, you will have a dead calf (and possibly a cow, if you've left it for 3 or 4 days) on your hands.
