To make her stop producing milk.
Yes, when they are to old to breed and the milk production drops off they are eaten. Smaller (family) dairies usually care more about their cows and will sometimes give a cow a year off if she is normally a good milker, but eventually she will have to be replaced by a younger cow. On occasion a favored cow may be turned out to field and retained as a farm pet or mascot. That is if it is a small grass based dairy and not a confinement dairy operation.
I am sure that you could, but dairy cows are more valuable to farmers for the milk they produce, not their meat.
For beef and dairy cows, lactation period begins immediately after a calf is born. For beef cows, the lactation period ends when their calves are weaned off of them. For a dairy cow, the lactation period ends when she is not longer being milked and allowed to dry up so that she can focus on putting energy into growing the calf inside her. The dry period for a dairy cow is shorter than a beef cow's: two months for a dairy cow, and four to five months for a beef cow.

What are somw of a dairy cow's adaptations?
It's so that, or the belief is, that it keeps the udder more clean and keeps the tails from hitting the faces of the dairy workers.
Cows finish lactation when they are being dried off; i.e., when they're weaned form their calves, or when the dairy farmer has to dry them off to give them rest before calving in two-months' time.
This question refers to dairy calves. The meat is called veal, but the legs are not removed at birth in any case in beef or dairy cattle.
It is most effective to use lotion after showering.
YES!! Drying off a cow prior to calving is VERY important. It's not to increase colostrum, but to generate it right after the calf is born. Cows need to rest and gain a bit of weight too, with a couple months taken off from being milked, before they calve and produce milk again.
by drying off
No no no no no!!! DEFINITELY not in the straight form, as she will easily get toxicity from it!! You're better off giving it to her in a loose-mineral form with other minerals like iron, cobalt, salt, copper, manganese, etc. Cattle only need like 0.5 mg of Selenium per day, and only if you are in an area that is Selenium deficient. If you are NOT in an area that is NOT Se deficient, then you can completely forget about feeding a dairy cow selenium!
