Kingsbury County independent. (DeSmet, Kingsbury County, S.D.) 1894-1929, 1906-06-08

In an earlier number OF this series
the economy of substituting home
i grown feeds rich in protein for pur-
chased feeds was discussed upon the
basis of experiments conducted by c..
b. Lane at the New Jersey station,
n in a later number. Ohio station
work, by G. G.. Williams, was referred
to as showing hat corn silage may
| replace with profit a large part Of the
grain ration usually fed to dairy cows.
Additional Investigations of a similar
nature are here briefly noted with a
view OF emphasizing again the econo-
my OF the fullest possible utilization OF
home grown products in feeding, es-
pecially of those products rich in pro-
TEN, such as alfalfa, clover, cowpeas
and other ~leguminous crops.
At the New Jersey station three ex-
periments, similar in nature TO the
earlier work cited, were by
c. b. Lane to study the substitution OF
alfalfa hay, cowpea hay and soy
silage for purchased feeds. Each ex-
pertinent was made with four COWS and
covered two periods of fifteen days
each, the third experiment being duplf-
Gated.
In the first experiment a ration
consisting of ~eventee pounds of cow
pea hay and thirty-six pounds of corn
silage was compared with a ration
made up of five pounds of cornstalks,
thirty-siX pounds OF corr silage, four
pounds of wheat bran, three pounds of
dried brewers grains, and two pounds
Of cottonseed meal, The cowpea a
ration contained 800 pounds OF pro-
tein and had an estimated nutritive ra-
ito of 10. The feed ration contained
$40 pounds of protein n had an es-
timated nutritive ratio of l:5. The
cowpea hay ration was produced n
tirely on the farm, while over two
thirds of the protein of the feed ration
was purchased. On the cowpea hay
ration the daily yield averaged 23.7
pounds of milk. containing 1856 per
cent. OF fat; on the feed ration il was
25.7 pounds OF milk. containing All
per cent. of fat. The feed ration pro-
duced S.S per cent. more milk, or l5.2
per cent. more butter. than the cowpea
hay ration. At market prices for feed
ing stuffs the cost of producing 100
pounds of milk was S9.Sc, and of pro-
ducing one pound of butter S.S2c, when
the cowpea hay ration was fed. When,
however, the feed ration was given, the
cost of production was 60.5c per hum
dred for milk n l2.6c per pound for
butter. With milk at 81 per hundred,
these results were interpreted as show
ing an increased profit for herd of thir-
ty cows of 1920 per month from the
home grown ration over the feed RAJ
ton. However, il is believed hat a
combination OF coarse and fine feeds Is
necessary to produce the best results.
In the second experiment the home
grown ration consisted of thirty-six
pounds Of soy bean silage, eight pounds
of alfalfa hay n six pounds Of corn
meal. The protein content OF the ra-
ton was 3.64 pounds, and the osti-
mated nutritive ratio was 1.5. The
feed ration consisted Of thirty-sX
pounds of corn silage, four pounds of
wheat bran. four pounds Of dried
brewers grains and two pounds OF
sottonseed meal. The protein content
was 3.45 pounds and the estimated nu-
tritive ratio was 1.6. The average Gaily
yield of milk per COW was 27.2 pounds,
testing SO per cent. of fat on the home
grown ration, and 25.7 pounds eating
3.8 per cent. of fat on the purchased
ration. The home grown ration pro-
duced, therefore, 5.S1 per ,ent. y ole
milk than the purchased ration. Tne
butter production was practically tae
same on both rations. on the home
grown ration the food ccsg OF $50
pounds of milk was SIS cents, and of
one pound of butter 1876 cents. and On
the purchased ration O. cents ana lES
cents, respectively, showing a ccn =
cradle saving when home grown iced
ing stuffs were used.
The third experiment showed that
when protein was supplied IN the form
Of c~ottorseed meal rather than wheat
bran and dried brewers grains, the
saving In cost of production was ll.9
cents per 100 pounds of milk and 3.3
cents per pound of butter.
In still later work at the New Jersey
station. G. A. Billings compared a ra-
ton consisting Of IA pounds of al
falfa hay, 35 pounds OF corn silage and
2.5 pounds of ~cottonseed meal with a
ration made up OF 40 pounds OF corn
silage, 2 pounds of cornstalks, As
pounds Of wheat bran. 4.5 pounds of
dried brewers grains and 2 pounds Of
~cottonseed meal. The experiment was
made with eight cows and lasted sixty
days. The results showed that the
purchased feed ration produced 81 per
cent. more milk and 7.2 per cent more
butter than the alfalfa hay ration. but
that the cost was much greater. With
