II. In May, 1914, six acres of rye were cut for silage. We
found that the rye furnished a heavy crop of green material
which made good silage. This rye was fed in quantities of
from 30 to 40 pounds to each cow per day during July and
August, last summer. Another field of four acres of rye
was cut early in June and made a palatable hay that has
been utilized in feeding the dairy cattle during the past
winter. Circular 31 contains a full account of the methods
employed in handling the rye and its value as a feed for
i dairy cows
III. In an experiment in feeding all the cows first on
ground wheat and then on wheat bran, it was found that one
of these feeds might easily be substituted for another. The
cows were fed in this experiment during August, September,
October and November, and the feed was so alternated that
they were fed during one month on wheat and the next
month on bran. For every pound of bran that was supplied
in the grain mixture the cows produced 3.23 pounds of milk
and for every pound of ground wheat they produced 3.01
pounds of milk. In other words they produced 7.3 per cent
more milk from bran than from wheat. This information is
extremely important as an economic proposition during such
a season as last summer when wheat was worth less than
bran. For a time wheat was selling at 77 cents per bushel '
(1.3 cents per pound) or $26 per ton; and bran at that time
was costing the Experiment Station $30 per ton. In other
