Direct-fed microbials are feed additives that stimulate natural, nonpathogenic gut flora in an attempt to stimulate competition against potentially pathogenic gut flora. Previous research involving direct-fed microbials offered in a liquid suspension to lightweight stocker calves produced no effects on growth or health performance. Therefore, the objective of our study was to evaluate the effects of a directfed microbial offered as a dry suspension on feed intake, average daily gain, and morbidity of highly stressed beef heifers.BeefMicrobialsProTernative stress formulaGrowthFeed intakeHealthConference paper
