It depends on the cow. Sometimes it can be a couple weeks before a calf is born that they start springing (producing milk), or it can be right after she gives birth. Every heifer and cow is different.

After a cow calves should you milk her or not?

It depends. Is she a beef cow or dairy cow? Are you wanting to keep the cow with the calf or separating the calf from the cow? Usually with beef cows you don't bother with milking them unless you have to because the calf isn't up and suckling soon after birth and you want to encourage the calf to be up and suckling, or to get some milk from a cow or heifer that won't accept her calf right away to feed that calf with. With dairy cows, though, if you've separated the calf from the cow right away, it's ideal to milk that cow to collect the colostrum to feed that calf--and other calves--to the benefit of the calf's health. But, if you are wanting to keep the calf with the cow for a couple of days, then no, it's not necessary.


How do you help a cow give birth?

First, you have to get her in a head-gate, if she's a bit nervous of you poking around her rear. Then reach inside the birth canal to see if the calf's coming normally. If it's not, you will have to correct the calf yourself or phone the vet to come out and help you. Get the calving chains or calf puller on the calf and start pulling. Pull out and down, and pull when the cow strains. Once the calf is out, get it breathing by clearing the air-way and tickling its nose or ear with a clean piece of straw. Once and if the calf starts breathing and shaking its head, move it to a small pen where you can let the cow in with her new calf. Keep them there for a couple hours or until the calf has been up and suckling at his mother's udder. If you cannot pull the calf out without causing injury to the cow or calf, get the vet out to do a C-section on the cow.


How long is a cow a heifer?

A cow is a mature female bovine that has had a calf. She was a heifer before she had her first or second calf.


Why does a cow lick her calf?

It's an instinctive way of bonding with it. It's always a great sign to see when the calf first comes out, is when the cow turns around and starts licking her calf to not only remove the fetal membranes, but to initiate the bonding process between mom and baby.


What comes first cow is separated before calf is born or cows udder fills with milk?

It depends on the cow. Heifers sometimes will bag up (udder fills with milk) for weeks before they calve, other times they will bag up after the calf is born. Most cows will bag up a few days before a calf is born, so it can be either or.

Do cows have to mate in order to lactate?

Not quite; they have to give birth to a calf in order to lactate.


Why do cows continue to lactate when they no longer have a calf?

Because people milk them. Same stimulation as if a calf was sucking the teat.


Do heifers lactate like cows do?

No. Heifers, being young female cattle, don't lactate until after they've had their first calf, which is typically at 24 months of age. A heifer remains a heifer, from birth, until she's had her first or second calf, whereby she is considered a cow. But until then, heifers don't lactate like cows do, and when they do lactate after birthing a calf, they typically produce less milk than their older counterparts.


Do cats have milk before they give birth?

No, cows must be delivered of a calf in order to lactate, or produce milk. Most large dairy farms will remove the calf from the cow right after birth and give it milk replacer, and this will allow the cow to be milked to maximum.


Do cows need to be constantly pregnant to continously give milk?

No. Cows can be open and still be able to lactate. They must have GIVEN BIRTH to a calf in order to be able to lactate.


Why doesn't a mother cow give milk when there is a calf in her stomach?

A calf doesn't grow in a mother cow's stomach. It grows in her womb or uterus. And cows are fully capable of being able to lactate (give milk) while a fetus is growing in her womb, and it's always to feed the last calf she gave birth to. A cow, however, will eventually stop milk production when her calf is weaned from her several months before she gives birth to her next calf.

Calf muscle is the part toned by jogging.We give different kind of works to all kind of organ/part in our body,except Calf muscle.That is the reason for people when they first jog/run they feel a calf muscle pain.After years of resting,when it starts work, it starts paining as the reason of the calf muscle starts fat burning in their parts.

How long can a heifer be in labor?

Heifers don't lactate prior to their first calf. However, they may start lactating several weeks before giving birth, but they aren't lactating like a mature cow does.


Can a heifer be pregnant coming in heat and starting to lactate?

No. A pregnant heifer will rarely come into heat, and her heat period will only be once or twice during her pregnancy, then stop until after she has her calf. But she will not go into heat and start to lactate at the same time she's bred. She can only either be pregnant and have a small chance of coming into heat, or be pregnant and start to lactate (which only happens when she is nearing the end of her pregnancy).
