I certainly won't tell you how to raise cattle :) but I'm going off
sources like this:
Referring to this paper (caution: paywall)
"Domestic ruminants in developed countries are often fed an abundance of
grain and little fiber. When ruminants are fed fiber-deficient rations,
physiological mechanisms of homeostasis are disrupted, ruminal pH
declines, microbial ecology is altered, and the animal becomes more
susceptible to metabolic disorders and, in some cases, infectious
disease. Some disorders can be counteracted by feed additives (for
example, antibiotics and buffers), but these additives can alter the
composition of the ruminal ecosystem even further."
That being said, I'm sure the positive health impact of NOT raising
cattle in feces up to their ankles is substantial (skip to about 5:30):
So part of the effect of grain-based diets on cattle is direct
(digestive problems) and part of the effect is indirect (concentration
of animals into feedlots, which is only made possible by a grain-based
diet). Then there is the problem that grain-based diets for cattle
create and spread acid-resistant E.coli (the strains that cause actual
sickness and death in humans because they can survive the digestive tract).
It's clear that if you want to make cows as fat as possible as quickly
as possible without regard to their health, you should feed them lots of
grain and grain products. I think there is a lesson here for humans.
That being said, I don't blame anyone for feeding grain to their
cattle...when we subsidize it so heavily to make it so cheap, it's the
obvious thing to do. And sustainable grazing is actually a lot of work,
because you're moving the cattle around daily with small electric fences
in order to mimic the movement patterns of native grazers (like
buffalo), which move around continually and let the grass regenerate
instead of eating it down to the ground where they are before moving on.

By that standard, fruits and nuts are really just vegetables because
they're derived from plants. That may be technically true, as
"vegetable" is not a precisely defined term -- but commonly understood
usage, including the "food pyramid", defines "vegetables" as separate
entities from other plant products such as fruits, nuts, grains, and
Wikipedia gets it about right: "The noun vegetable usually means an
edible plant or part of a plant *other than a sweet fruit or seed.*
[emphasis mine] This usually means the leaf, stem, or root of a plant.
However, the word is not scientific, and its meaning is largely based on
culinary and cultural tradition."
