Abstract

Bovine respiratory disease (BRD) has a devastating economic impact on the beef industry. The annual estimated cost of BRD is well over $600 million. A possible way to mitigate the devastating effects of BRD is the supplementation of Saccharomyces cerevisiae. The supplementation of yeast has the potential to offset the impact of BRD due to its ability to alter the innate immune response, directly interact with pathogenic bacteria within the GIT tract, and/or through alteration of ruminant metabolism. To further evaluate yeast supplementation as a means to improve health, performance, and immunity in cattle, a receiving and immune challenge study was conducted to evaluate the effects of active dry yeast, Saccharomyces cerevisiae subspecies boulardii CNCM 1-1079 (SC; Lallemand, Inc.), in feedlot steers.
