A cow can lactate for as long as a couple years if she is still being milked, or if her calf hasn't been weaned (or she hasn't weaned her calf). However a cow is most productive during her first 3 to 4 months of lactation after parturition.

∙ 13y agoYou have to wait 24 to 48 hours before you can get "normal" milk from the cow, because from the time she drops her calf to around 48 hours later, she will be producing colostrum, which is more important for her calf than for you to collect and drink.

∙ 13y agoIF (and ONLY if) the calf cannot get up on its own and nurse his mother, should you milk the cow out and bottle-feed or tube the calf with her colostrum. BUT, if the calf CAN get up and suckle (AND his mother lets him) then don't waste your time milking that cow out, as the calf is needing the milk more than you do.

∙ 12y agoI'm not too sure what you mean here. Are you asking about when a cow giving milk right after her last calf how soon she'll have her next one, or when she starts lactating during her third trimester when to expect a calf?

∙ 11y agoShe can't be milked again. That's the whole purpose of the drying-up process: you get a cow to not produce milk again, even if you suddenly decide you want some milk from her. If you do that, you won't get even a drop of milk.
However, in order to get her lactating again, you must get her bred (no not you yourself, I'm talking putting a bull with her or via artificial insemination) in order for her to become pregnant with a calf, let her carry it to full term and then the tap will start flowing again, so to speak.
