Nutraceuticals: An Alternative Strategy for the Use of Antimicrobials

Michael A Ballou et al. Vet Clin North Am Food Anim Pract. 2019 Nov.

Abstract

Livestock industries strive to improve the health of their animals and, in the future, they are going to be required to do this with a continued reduction in antimicrobial use. Nutraceuticals represent a group of compounds that may help fill that void because they exert some health benefits when supplemented to livestock. This review is focused on the mechanisms of action, specifically related to the immune responses and health of ruminants. The nutraceutical classes discussed include probiotics, prebiotics, phytonutrients (essential oils and spices), and polyunsaturated fatty acids.

Keywords: Health; Immune; Nutraceutical; Phytonutrient; Polyunsaturated fatty acid; Prebiotic; Probiotic.
