I do not think the word "efficient" means what you think it means.
Recall that the USA (one of the most productive nations in the world) is
only 19% arable, and much of that only due to massive
government-subsidized dams and irrigation projects. It is maximally
efficient to graze animals on land that cannot grow crops.
Also, I think Dave knows more about cattle than you or I do :) I
learned that lesson earlier.

Attempting to "scale up" food production is the cause of most of our
problems. It is most efficient and least damaging to grow and consume
local food grown appropriate to the water, soil, exposure, and shade
conditions of the land (see: "permaculture"). Yet we heavily subsidize
industrial-scale farming that strip-mines topsoil, pollutes water, and
requires massive energy input both for fertilizer and transportation.
Factory farming is destructive whether it produces cows or soybeans.

Then I have better things to do than read your posts.
You might consider that what vegetarian propaganda calls the
"inefficiency" of animals grazing is, in reality, nutrients being
returned to the land in the form of dung -- which actually *increases*
the fertility and productivity of the soil vs. the dry, dead grass that
would otherwise build up...
...and versus human consumption of grains and vegetables, which results
in those nutrients being flushed into the nearest body of water.
Yes, properly managed grazing *creates* topsoil...which should be common
sense, or the Serengeti and Great Plains would have blown away into dust
tens of millions of years ago. We're currently living on the drawdown
of the accumulated capital of millions of years of grazing (among other
