The purpose of this publication is to provide fundamental information that must be understood before attempting to conduct a feed trial. The concepts and procedures described here are valid for most situations involving a comparison of two feeds. Any trial involving more than two feeds raises issues that are beyond the scope of this publication. Those issues are covered in university statistics courses on design and analysis of experiments.

We suggest that pork producers adopt a "best cost" feeding program tailored to the operation and based on sound nutritional principles. Feed cost per pound of gain is a major item separating high and low profit pork producers. University and feed industry personnel provide information to help producers develop an appropriate feeding program; however, sometimes that information is deemed inadequate. Often a feed trial is conducted on the farm to determine which feed is "best."
