A Graphical Presentation of the Financial Phases of Feeding Experiments

Illinois Agricultural Experiment Station

Abstract

The difficulties of properly presenting the financial aspect of feeding experiments are so obvious as to require little comment. Against the ordinary method of procedure, in which prices of feeds and live stock prevailing at the time of the experiment is in progress, are used in computing profits or losses on the different lots of animals, it may be objected that the particular combination of prices used will probably never occur again. In fact, it may be that a shift in the prices of feed and livestock that may normally occur from year to year, may change entirely the financial complexion of the experiment. Hence, the fact that one system of feeding returns a profit over another during one year, is no great assurance that it will do so the following year.

The so-called "financial results" of a feeding experiment are really not experimental results at all, since they depend so largely upon market conditions, which are not under experimental control.
