bleed our pocketbooks-they have up
set our sense of values. We knew a
year or two ago that we could afford
10 pay -, 20 or - cents hundred
weight for skim milk. but what is it
safe 10 paw now?
The feed market Is wearing such n
completely new front that most of us
can scarcely more than guess. When
II iS~ realized however that Michi-
gan's estimated annual production of
skim milk is 1869, $4,000 pounds, we
can readily appreciate why this matter
Is one of such immediate interest and
Importance.
The results of n study Of this sub
iect completed recently by the expert
ment station of the college are ac-
cordirgly of much value for they an
swer. at least i'm part, the ever-recur-
ring question. "How much can l af-
ford to pay?"
To arrive at an answer Ii was first
necessary. of course. to determine
what milk is worth as a feed. For
this purpose the results of feeding en-
periments conducted by many stations
415 pigs fed cereal grains only (corn.
wheat, rye and barley includeD made
an average gain of 100 pounds for
each 1863 pounds of grain eaten.
Further. it was found that i'm the
case of 325 pigs which were fed ra-
ton of cereal grains (corn. wheat and
rye included. with skim milk as n sup.
plement, each pig made an average
gain of 100 pounds from 2G6.9 pounds
Of grain and 1851 pounds of skim
milk, resulting In saving of 2196
pounds OF grain-Or I'm other words
100 pounds Of skim milk replaced %
pounds of grain.
Having the grain value of skim
milk when fed as supplement to corn
and other cereals, the determination
of its money value is relatively simple.
Thus, when the price of grain per
100 pounds is S1.OO, 100 pounds of
skim milk rs supplement to cereal
grains (fOr pigs) is found to be worth
% cents; when the price of grain is
S1.25, skim milk Is worth 81 cents !:
when grain Is worth $50 a hundred
pounds, skim milk is worth ~ cents !;
when grain Is worth S175, skim milk
Is worth 40 cents; when grain is worth
$500, skim milk is worth IS cents;
when grain Is SD skim milk is worth
81 cents: when grain Is worth $3.50,
eli to,
grain Is worth S2.75 hundredweight,
skim milk is worth II cents; when
grain is worth $500, skim milk is
worth 81 cents; when grain is worth
$3.25, skim milk Is worth 81 cents |;
when grain is worth $3.50. skim milk
is worth % cents when grain Is
worth 1913, skim milk is worth 81 90 /;
when grain Is worth $500. skim milk
is worth SLIP. and when grain is
worth $4.25, skim milk Is worth SLID
a hundredweight.
This table shows that when prices
Of cereal grains range from 5000 to
$4,000 per ton, as has been true dur
ing the winter of 1917-191S, skim milk
will range from 40 cents to S120 per
hundredweight In value as supple
mentary feed.
The value Of this by-prOduct of the
dairy as supplement to corn and
other cereal grains Indicates that when
1t Is available II can be combined to
excellent advantage with the farm
grown grains for pig feeding. If it Is
lab f.,. insy
farm where the whole milk is sold to
the retail trade or for condensng pur-
poses. It, becomes necessary. If best
results are to be secured, to purchase
IL or some other protein feed to com
bine with the cereal grains. Tankage,
most commonly used in place of skim
milk for feeding pigs, and in order
that n comparison of these different
supplements could be made. the re-
suits of a large number of feeding
trials from number of different ex-
married..
Where 32J pigs consumed an aver
age Of 1903 pounds of cereal grains
per 100 pounds gain, with 1851 pounds
Of skim milk as II supplement- 100
pounds Of the supplement replaced 2S
pounds of grain; where 332 pigs CON
sumed an average Of 379.3 pounds Of
cereal grains per hundred pounds
gain. with 42.5 pounds of tankage as
supplement, 100 pounds of the tank
age replaced 1929 pounds of grain;
where 100 pigs consumed an average
Of 1888 pounds of cereal grains for
100 pounds gain, with 1912 pounds of
middlings as a supplement, 100 pounds
of the middlings replaced 1862 pounds
of grain; where 106 pigs consumed an
average Of 377.3 pounds of cereal
grains for every 100 pounds gain with
51.7 pounds of oil meal as n supple
ment. 100 pounds of the oil meal re-
placed 26l.7 pounds Of grain, and
