You keep on running from the data, swamp.  No surprise.

You don't say.

We have to find weight before we can calculate calories.

Running so fast you indicated snipping the same paragraph twice.

over a year; at 450kg (1000lb) at eighteen months old, or at

Scary data, huh.

To remind you- I'm calculating feedlot or high concentrate feed, to gain.

You're crazy.

We know that.  What happens to all those calories they eat then?

Yes, water.  An increasingly scarce resource.  We can look at feed:beef
with water content if you prefer.

Not so.  The data you keep snipping indicates appalling waste.

That's the way it's going.
