Cull cows can be put on pasture, or fed a mix of hay and grain before slaughtering them. It's advisable to put them on a bit of grain so that the meat doesn't taste to strong or is tough. Of course how the meat turns out depends on the breed and how long it is hung for.
It's not really important whether you feed a cow right before it gets butchered. When it gets butchered, the stomach contents are going to be cut out anyway, and the meat kept to be eaten.
But, if you mean to fatten up a cow before butchering, you may wish to feed it a little bit of grain (around 10 to 20 lbs per day) along with hay and/or grass for a few weeks before sending her to the butcher.

Yes, but only in moderation.
Dairy cows, even though they are not lactating, still have higher nutritional demands than dry beef cows, so baleage (a form of silage) is a recommended feed to feed to them.
First let us get some terminology straight here. Male cattle are called Bulls and females are called Heifers (if have never calved a calf) or Cows if have calved a calf. Neutered Cattle are called Steers. Bulls are neutered if not of breeding quality and the Farmer wants to feed them out to fatten them and then slaughter for use as beef. This is where your beef comes from.
It's supplemental protein for beef cows that are on grass diets.
Veal does not come from any part of a cow. Veal is the meat from dairy bull calves that are not needed in dairy production and are sent either for slaughter or to be fed a special feed prior to slaughter.

None. Cows eat grass, hay, silage and grain, not any sort of animal meat like "beef nut."
No. Dairy cows have much larger udders than beef cows do. A dairy cow has been selected to produce more milk than what she can feed her calf to meet the farmers' demands for more milk to be produced per cow per day.
Ranches that are defined as companies, like those found in Montana and Alberta, for instance.
"Menudencias" are the internal organs of the animals (cows, steers, heifers) that are used after the slaughter for several uses, chemical, medical, feed, etc.
