grown products i'll feeding. especially OF
hose products rich in protein. such as
alfalfa. clover. owpeas and other
leguminous crops
AT the New Jersey station. three ex-
periments, similar in nature TO the
earlier work cited, were conducted by
e. Is. Lane to study the substitution OF
alfalfa hay. cowpea hay, and soy bean
silase for purchased feeds. Each eX-
pertinent was made with TOUR COWS
and covered two periods of fifteen days
each. the third experiment being dupl-
Gated
In the first experiment Il ration con-
sisting of IL pounds OF cowpea hay and
80 pounds of corn silagc was compared
with Il ration made up of . pounds or
c~ornstalkS. 80 pounds of corn Silage. 4
pounds of wheat bran. 3 pounds of dried
brewers grains. and = pounds OF cotton
seed meal. h cowpea hay ration con
tanned 800 pounds of protein and mad
an estimated nutritive ratio of l:6. The
feed ration contained $50 pounds OF
protein and had AN estimated nutritive
ratio of Ia. The cowpea hay ration
was produced entirely on the farm.
while over two-thirds of the protein OF
the feed ration was purchased. on tho
cowpea hay ration the daily yield aver
aged 23.7 pounds of milk. containing
1856 per cent. of fat: on the feed ration
it was a5.7 pounds of milk, containing
Al per cent. of fat. The feed ration
produced So per cent. moro milk. or
1o.2 per cent. more butter. nan the
cowpea hay ration. AT market prices
for feeding stuffs the cost of producing
100 pounds of milk was 39.S cents, and
of producing l pound of butter $50
cents, when the cowpea hay ration was
fed. When. however, the feed ration
was given. the cost of production was
60.5 cents per hundred for milk and
1916 cents per pound for butter. With
milk at 81 per hundred. these results
were interpreted as showing an in
creased profit for Il herd of thirty COWS
of $3.50 per month from the home
grown ration over the feed ration.
However. it is believed that Il coln-
bination of coarse and fine feeds is
necessary to produce the best results
In the second experiment the home
grown ration consisted of &c pounds of
soy bean silage. s pounds of alfalfa hay.
and 6 pounds of corn meal. The protein
content of The ration was 1854 pounds.
and the estimated nutritive ratio was
1:5. The feed ration consisted of &
pounds of cornstalks, &c pounds of corn
silage, 4 pounds of wheat bran. 4 pounds
OF dried brewers grains. and . pounds
of c%ottonseed meal. The protein con-
tent vas 3.45 pounds n the
estimated nutritive ratio was 1:6.
The average daily yield of milk
per COW was 21.2 pounds. test
ing SO per cent. of fat on the home
3.S per cent. of fat on the purchased
ration. The home grown ration pro-
duced, therefore. 5.S1 per cent. more
milk than the purchased ration. The
butter production was practically the
same on both rations. On the home
grown ration the food cost OF 100 pounds
of milk vas So cents. and of ] pound
of butter 1875 cents. and OH the pur-
chased ration 65 and 14.6 cents. re-
spectively. showing Il considerable saw
ing when home grown feeding stuffs
We're used.
The third experiment showed that
when protein was supplied in the form
of ~cottonseed meal rather than wheat
bran and dried brewers grains, the
cents per 100 pounds of milk and 3.3
cents per pound of butter.
In still later work at the New .Jer-
sey station. G.. A. Billings compared
Il ration consisting of IA pounds of
alfalfa hay. 30 pounds of corn silage,
and 2.5 pounds of cottonseed meal with
"a ration made up of 40 pounds Of corn
c1vQ ro nnI1nHc Of rOrt,ct.1lo 49,
pounds of dried brewers grains. and .
pounds of c~ottonseed meal. The expert
ment was made with 8 COWS and lasted
sixty days. The results showed that
the purchased-feed ration produced 81
per cent. more milk aud 7.2 per cent.
more butter than the alfalfa hay ration,
but that the cost was much greater.
With alfalfa hay inc corn silage VAL
ued at h cost of producing 100 pounds
OF milk on the alfalfa ration was Al 6
cents and on the feed ration IT'S cents.
and the cost of producing I pound of
butter 1911 and 1885 cents, respect
ively. showing a much greater profit
from Il home grown ration. The profit
in feeding the alfalfa ration over the
purchased-feed ration was estimated at
33.7 per cent. for milk and 31.5 per cent.
for butter. These results were aver
aged with those obtained in the earlier
experiments at the station. the results
showing an average saving IN cost OF
production by using home grown feeds
! Of PA per cent. for milk and 20.2 pei
cent. for butter.
AT the Maryland station G.. L. Doane
compared leguminous crops and com
mercial feeding stuffs as sources OF
protein in IA number of experiments.
In a test with fifteen COWS a bal
anced ration of alfalfa hay and corr
meal produced more milk than Il bal
anced ration of corn silage and mixet
grains. In another test with three cow!
a balanced ration of alfalfa hay ant
corn silage without grain did not civ,
as satisfactory results. judged from tn,
yield of milk. as Il ration of corn silag,
and mixed grains. indicating that ap
parcntly some concentrated feed wa
necessary for a maximum yield
In. several tests with the entir
herd during two winters. cowpe;
silase was compared with corn silage
the results being interpreted as prov
ing the superiority of the cowpea 81
lase. These results show that alfalf
and cowpeas. in addition to enrichin
the soil. may be grown for the purpos
of supplying to a very large extent tn
protein In rations for cows.
At the Tennessee station A. NJ, Soul
and S. Il. Barnes showed several year

tuted with profit for q part of the cot
