Don't waste your time. This is supposed to happen, as what will happen after you wean the calf from the cow and the cow dries up after a few days of not being milk. If you have already rebred the cow a few months prior to weaning, then you'll have to wait until after she's calved to begin milking her again.
It is a good idea to keep them separated for about a month, this is to ensure that the mother wont let the calf start to suckle again.
A stray calf is a calf that has wandered off away from his mother, and/or has been separated from his mother by either the herd moving to another pasture, or by them being sorted, or simply by the fact that that little calf went exploring a little farther than he should have.
Only if she has given birth to a calf before being bred again and continuously milked since then, then yes. But, if that cow has given birth to a calf, was dried up for some reason before being bred again, no.
A cow and calf should not be separated unless you are weaning them. Thus, if you are asking about weaning a cow from her calf and vice versa, you should keep them separate for at least 6 to 8 weeks, longer if the calf tries to go back to suckling his momma again when you put them back together.
He could, but in most cases he either chooses not to because the cows are already doing a fine job of it, or he can't because the producer (or "farmer") has separated him from the cows with calves for the time being until breeding season starts up again.
A calf raise is an exercise for the calf muscle where someone raises their heel off the ground, to stretch the calf, and lowers it again.
This depends on when you first put the calf on the bottle. But mainly, it'll be a few months that a calf goes from being dependent on the bottle to being fed as a feeder calf.
Between 2 to 6 weeks.
the young is called a calf when producing called mating
No. Once a cow is pregnant she won't have any signs of heat again, until after she gives birth to her calf.
It means that the calf is being separated from its mother so it doesn't drink milk anymore, or is not allowed to drink milk from a bottle or bucket (if it's bottle- or bucket-fed) anymore, and is made to get used to no longer drinking milk for the rest of its into-adult life.
That's your opinion, and it depends on whether you are referring to dairy production, weaning as separating like that in beef herds, or another reason that requires a calf to be separated from its dam or vice versa. As far as dairy production is concerned, it may seem cruel to separate a calf from a cow that has just bonded with it, like after a day or two, but it's necessary because it's not a great idea nor is it productive to have a whole pile of calves loose in the barn or having to contend with being separated from their mothers for a short time twice a day when their mothers are being milked. The cows only bawl for their calves for a few days, then soon forget them and settle down to regular routine. It is not cruel to separate a cow from it's calf during a time when calves MUST be weaned from their dams, especially when they don't need their mother's milk anymore. You may consider it cruel if the weaning process involves separating cow and calf into separate pastures where they can't hear, see or smell each other, but not if they are only separated by a fence or the Eezy-Wean nose ring is used for a short period before the calves are actually separated from their dams. It is not cruel if you have to separate a cow from her calf if the cow cannot care for that calf for whatever reason: either she died from a complications, cannot get up after a difficult delivery, doesn't have enough milk to feed her calf and the calf needs to be orphaned onto another cow, the cow won't accept her calf despite everything a producer tries to do and has to bottle-feed or put the calf on a nurse cow, the calf has to be kept in a protected area because it is sick or injured or otherwise too weak to be able to keep up and suckle from its mother, etc. in these cases, mom and calf have to be separated, and, if and when necessary reunited only briefly to feed the calf its mother's milk.
