The question ought always to be, How much can a cow eat and drink? not,
How little can she get on with? Grain and forage are to be turned into
milk, and the more of these foods our cows eat, the better we like it.
If these machines work imperfectly, we must get rid of them at once and
at any price. It will not pay to keep a cow that persistently falls
below a high standard. We waste time on her, and the smooth running of
the factory is interrupted. I'm going to place a standard on this farm
of nine thousand pounds a year for each matured cow; I don't think that
too high. If a cow falls much below that amount, she must give place to
a better one, for I'm not making this experiment entirely for my health.
The standard isn't too high, yet it's enough to give a fine profit. It
means at least three hundred and fifty pounds of butter a year, and in
this case the butter means at least thirty cents a pound, or more than
$100 a year for each cow. This is all profit, if one wishes to figure it
by itself, for the skimmed milk will more than pay for the food and
care.
