H0pO to Develop Dairy Production
Is Sh01U71 By Demonstration

must have good producing cows and
at the same time must be economical
in feeding. 1t is not meant that the
cows be given light rations, but that
those feeds be used that produce the
most milk at the least cost to the gal
lon. In dairylar it is not the milking
of so many COWS twice each day that
governs the cost Of production, but
herd puts in the pal ach day.
Some feeds are betts. . producers /
than are others.
Starting the Test.
The object OF this test was to .
make a comparison of the value of .
bright cottOnseed meal, peanut meal /
and velvet-bean meal Oceans and !
pods ground together) for milk pro .
ducton.
For the work, nine COWS were Sc /
.ected from the dairy herd and di- .
vided into three lots Of three cows .
each. The feeding test was divided
into three periods Of twenty days
each with four days between periods .
for changing feeds. This was con
sidered advisable so that it would not
be necessary to make a sudden /
change in feed
The feeds in this test were not fed
in equal amounts but in as nearly
/ equivalent food nutrients as it was
possible to get them.
The Rations Used.
] The daily ratiOns were: All cows
were fed wheat bran 9 pounds, silage
] 12 pounds: in addition, lot I received
pounds cotton seed meal, lot II, 4
/ pounds peanut meal, and lot III,
pounds ve!vet-bean meal.
/ The first period began November
{ II and lasted twentv days. The sec
Ond period began December 5, and
continued for twenty days. The
bird pe~.od began December %. and
continued for t."e@ty days, closing
January i. 1911.
The Results.
During the first period the COWS
I'D on wheat bran. cotton seed meal
end e.!are produced OOPS pounds of
m5i3: those fed peanut meal produced
i l.04@ pounds of milk; those fed vel
vct-b"an meal produced 889.7 pounds
Of milk. During the second period
the cows fed on cottonseed meal pro
duced 1892 pounds of milk; those fed
peanut meal produced 1856 pounds of
milk, and those fed velvet-bean meal
produced 1,048.5 pounds Of milk.
During the third period the cows fed
on cottonseed meal produced 1851
pounds Of milk; those fed peanut
meal produced 1851 pounds of milk,
and those fed velvet-bean meal pro
duced 1902 pounds of milk.
The total amount of milk produced
during the three periods by feeding
cotton seed meal was 2,6O18 pounds
or 3O2.5 gallons; by feeding peanut
meal, 2,735.3 pounds or 1904 gallons:
by feeding velvet-bean meal, 2,S184
pounds or 327.7 gallons. This shows
that the velvet-bean meal ration pro
duced more milk than did either cot
ton seed meal or peanut meal. The
difference in the amount of milk pro-
duced by velvet-bean meal and pea
nut meal is very small, being a diff
ference of less than eight gallons.
The difference in the amount of milk
produced by veIvet-bean meal and
cotton seed meal is a little more than
25 gallons.
Feed Cost Per Gallon.
In reckoning the feed cost for each
gallon of milk, the feeds were priced
as follows: Cotton seed meal $50:
wheat bran $40; peanut meal $40;
velvet-bean meal $50; and siIage 81
a ton.
The feed cost of the milk produced
by feeding cotton seed meal was 1863
cents; for peanut meal it was Is
cents and for volvet-bean meal it was
16.5 cents a gallon.
From these figures we get the rel
ative value Of each of these feeds for
milk production. If cotton seed meal
IS worth $50 a ton, then. according to
the results Of this experiment, pea
nut meal is worth S45 ton and vel
! vet-bean meal is worth $500 ton.
