These cows consumed one pound of grain for each three
and one-half pounds of milk produced, and in summer had scant
pasture additional. In the fall and winter they had soy-bean _
hay and silage.
` The results indicate that half the wheat bran in the cus-
tomary corn-bran ration can be successfully replaced by velvet-
bean feed, at a slightly reduced cost. ‘
Velvet-Bean Feed Versus Bran
Beginning December 30, 1917, and continuing until Feb-
ruary 24, 1918, three of the cows in the foregoing experiment Ai
were fed a ration containing half velvet-bean feed and half
- corn meal, in comparison with a ration of half corn meal and
half bran. They received each ration for two weeks, and then
were alternated to the other ration the next two weeks, each
ration being fed four weeks, in all.
_ The amounts of milk produced during the several periods `
were almost identical, tho there was a slight increase in milk
from the wheat-bran mixture, as indicated herewith;

’l`he eows received the same ronghage as before. They ate
both rations well. showing that velvet-bean feed can, if neces- K
