Like I said, I don't doubt that antibiotics are necessary and used on
the major industrial feedlots. I'm just saying that in my experience,
which I think is typical for smaller producers throughout the
southeast US (and probably elsewhere), grain finishing doesn't
automatically mean antibiotics are required. My neighbor raises a
couple dozen head/year. He buys calves at auction, raises them on
pasture, finishes them on grain feed a month or so, then sells them at
auction. From there they go right to slaughter. They're already
finished, so feedlotting them wouldn't make sense economically. He may
be able to buy grain below cost due to subsidies, but believe me, the
margins in farming are sufficiently tight that they get no more grain
than he thinks is necessary to properly finish them.

Extreme overcrowding like that is never healthy.

It's the caloric density of grains, which allows cattle to be fattened
rapidly, and the customer's preference for grain-finished beef that
makes feedlotting economical. But feedlots could be feeding hay or
silage if grain weren't an option.

Yeah, that's an overcrowding problem.

I agree. I just happen to think that moderate amounts of grain
products are perfectly OK for most people.

No, that's not true. I already explained, back in the paleo/primal
thread, that subsidies don't make grains cheap. They make them
cheaper, but they're already cheap. Furthermore, cattle aren't fed
grain routinely while they're being raised. It's too expensive and
pasture/hay are cheaper and readily available. Cattle are finished on
grain because Americans like a nice, marbled steak, and you can't do
that with grass.

It's not that hard. The easiest way is to keep the number of livestock
low enough that they'll do that on their own. If you want to push it,
a little cross fencing and more active pasture maintenance is all it
takes.

First, you're confusing "vegetable", the noun, with the adjective.
Fruits and nuts aren't vegetables, but they are vegetable--they come
from organisms in the vegetable kingdom, AKA "plants".

Yes, Wikipedia does get it about right. But you stopped reading too soon:
"As an adjective, the word vegetable is used in scientific and
technical contexts with a different and much broader meaning, namely
of "related to plants" in general, edible or not — as in vegetable
matter, vegetable kingdom, vegetable origin, etc."
Seriously, nobody thinks vegetable oil comes from carrots and
cucumbers. Corn oil is in the gray area because most people consider
corn a vegetable, but peanut oil, soybean oil, olive oil...everyone
knows where they originate. Probably 95% of the population has no idea
what a "canola" is, but you can't blame the rapeseed industry for
using a different name.
