Yes. Any dairy cow that is culled from the herd as being non-productive is slaughtered for meat. Some cows that die on the farm don't make it as far as the meat factory, rather they get buried in the "dead pile" or "dead pit" or whatever it's called and decompose back into soil.
No. Holsteins are also slaughtered for beef, especially when they're no longer productive. Bull calves are also raised as veal calves. Most of the hamburger and veal meat come from dairy cattle that include not just Holsteins, but Jerseys, and Brown Swiss as well.
Jersey bull calves are slaughtered for veal. Jersey cows, when they're too old to be productive any more or are culled for productivity reasons, are slaughtered for beef, which is often made into ground beef for hamburger and such. Ultimately, though, Jerseys are not used for meat, but for dairy or milk production.
because cows have a healthier milk
"Fat cows are used for meat. In fact, fat cows will bring a premium price at market because of the high density and quality of marbeling of the meat that is obtained from fat cows. Lean cows produce tough meat that is lacking in fat, and fat cows are much preferred."
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.

Jerseys are mainly used for milk (dairy) production.
The genus and species of dairy cows commonly used for milk production is Bos taurus.
There is no "medicine" that is used for dairy cows to increase milk production. Only a particular growth hormone called rBGH or recominant Bovine Growth Hormone.
