Feeding Experiments with Leghorns

Abstract

Feeding experiments, particularly for the Middle West colleges, have taken a general trend toward the farmer's problem directly rather than toward deep scientific investigation.

At the Purdue Experiment Station we have been working for nine years endeavoring to find out about various kinds of animal protein, the proportions that should be used and their influences upon the hens. Bulletins have been published on our earlier experiments with Leghorns and duplicate experiments with Plymouth Rocks.
