Technical Abstract: The gastrointestinal microbial population, or microbiome, of dairy cattle is extremely dense and diverse, and factors within this ecosystem can be utilized to reduce pathogenic bacterial populations that may impact animal and human health, as well as improve animal productivity and environmental impacts. Probiotic and prebiotic feed additives have been widely used worldwide in the dairy industry to enhance milk production and feed efficiency. The individual efficacy of probiotics and prebiotics in dairy cattle is primarily due to specific microbial ecological factors within the gut of the dairy cow and her native microflora, which causes a competitive interaction between the native microbiome and introduced organisms from a probiotic. Herein, we explore the ecology behind the efficacy of probiotic products and how they may impact dairy production efficiency and can be used to improve both human and animal health.
