ROOTS AND slLAGE.
Comparison OF the Two In Rations For
MIX Production.

Prepared by Ontario Agricultural COL
lege,]
In the first place, it may be noted
that the Maine, Pennsylvania, Ohio
and Ontario experiment stations COM
pared the yield Of dry matter per acre
from roots and corn. Maine obtained
3,415 pounds Of dry matter per acre
from Swede turnips and $3.50 pounds
from fodder corn. Pennsylvania OBJ
tanned 1864 pounds of dry matter per
acre from mangels and 6,7G3 pounds
per acre from corn, Ohio 5000 pounds
dry matter per acre from mangels and
5000 POUNDS from corn and Ontario
5,034 pounds dry matter from mangels
and S,135 pounds from com.
So far as yield of dry matter per
acre is concerned it will be noted that
corn shows a marked advantage over
turnhps and mangels. BY dry matter
Is meant what is left after all the mois-
ture of the product has been driven OF
by heat.
The Ohio, Pennsylvania and Ver-
mont stations compared the dry matter
Of corn silage and roots for milk pro-
1uction. The following, taken from
Feeds and Feeding shows results from
these trials:
Milk from hundred pounds of dry
matter in corn silage and root rations:
Ohio station 1889, root ration gave
80 pounds of milk, silage ration gave
CO pounds of milk; Ohio station, 1890,
root ration gave SO pounds of milk,
Stage ration gave 60 pounds of milk;
Ohio station, 1891, root ration gave 62
pounds Of milk, silage ration gave G6
pounds of milk; Ohio station, 1892,
root ration gave 60 pounds of milk, 81
lage ration gave rs pounds of milk;
Pennsylvania station, root ration gave
81 pounds of milk, silage ration gave
50 pounds of milk; Vermont station,
root ration gave 113 pounds of milk,
silage ration gave 119 pounds of milk.
From the above results it will be seen
that in every case but one the dry
matter in the rations containing silage
proved more effective in the produc-
ton of milk than the dry matter in
the rations containing roots. 1t is
difficult to explain why such should be
the case unless the dry matter in the
silage rations was underestimate.
At the central experimental farm of
Canada turnips proved more expensive
and not much more effective than corn
silage for milk production
The Cornell station found that one
pound of dry matter in mangels is
slightly superior to one pound of dry
matter in corn silage; also that one
pound of dry matter in mangels is
equal to one pound of dry matter in
grain and that mangels may replace
half the grain ordinarily fed in a
ration composed Of grain, mixed hay
and silage.
At the Copenhagen station very ex-
tensive trials go to show that one
pound of concentrates in the form of
grain, bran and oil cake is equal to
ten pounds of mangels; also that for
cows one pound of dry matter in roots
s equal in feeding value to one pound
II Indian corn, mixed grains, or three
'ourths pound of cottonseed meal. 1t
vas also shown that the water con-
ent of the milk was not increased by !
he liberal feeding of roots.
The results of tests quoted above are |
lot exactly uniform, yet they all point |
% one thing namely, that for dairy
,ows the dry matter of roots is not |
different in feeding value
rom the dry matter in other foods.
