Some experimental design and statistical criteria for analysis of studies in manuscripts submitted for consideration for publication

This editorial discusses some statistical principles that may be useful in guiding authors of manuscripts submitted to Animal Feed Science and Technology (AFST) for consideration for publication. The editorial also discusses some common experimental designs and statistical models used by AFST authors, including some of the most frequent problems that cause misunderstandings and disputes among authors, reviewers and editors. The editorial is not meant as an exhaustive treatise on all possible experimental design and statistical issues that could arise, but as a general guide to correctly interpret results that are not meant to limit anyone's imagination, as there are many ways to evaluate and examine biological responses.
