PoRkMAklNG AS A SCIENCE.
Experiments With Various Sorts of
Hogs Feed for Fattening.
The Purdue University agricultural
station concludes, after series of ex-
periments, that skim milk is the most
efficient supplement to shelled corn or
corn meal in fattening hogs; that soy
bean meal is equally as efficient as lin
seed meal; that tankage is the most
efficient commercial feed used as a sup
plement to corn in fattening hogs under
market conditions prevailing during the
past five years. Another conclusion is
that the previous treatment and the
condition of the hogs when the fattening
process begins, have as much influence
on the subsequent gains as does the
KIND OF feed used. Still another con-
clusion is that in every experiment
conducted at the station during the
past five years there has been an in
crease in the rate of gain, decrease
in the cost of grain. higher finish and
a greater profit resulting from the use
of supplement in connection with
shelled corn or corn meal. as compared
