DIGESTIBILITY OF CORN FODDER FROM SO. CORN, FIELD CORN AND

SWEET CORN.

Time of experiment, October and November, 1890.

Animals used, sheep.

Total period, 12 days.

Feces collected, last 5 days.

A determination of the digestibility of the fodders from these varieties of corn was one of the necessary steps in an attempt to study their relative yield of digestible material.

Several hundred pounds of the green fodder corn were selected from each variety at the time the crop was cut and weighed. These small lots were stored in such a manner that they would dry without moulding and where they were safe from the depredations of

mice.

The partially dried fodder of the several kinds was finely chopped, thoroughly mixed, the daily rations weighed out, and samples at once taken to the laboratory, where the drying was completed by steam heat.

DIGESTIBILITY OF TIMOTHY HAY.

Time of experiment, December, 1890, and February, 1891.
Animals, sheep.

Daily rations, 700 grs.

Total period, 12 days.

Feces collected, last five days.

Two large lots of hay were taken from the mows. finely chopped and thoroughly mixed. The digestibility of this material was ascertained as work necessarily preliminary to a determination of the digestibility of various roots, wheat bran and gluten meal. The hay was very nearly all Timothy, a slight mixture of other grasses being present.
