Uso de suplementos alimentares no controle de doenças respiratórias em bovinos de corte

Abstract

Bovine Respiratory Disease (BRD), one of the major health challenges in animal production, particularly in confinement systems, is often prevented and treated using antimicrobials, highlighting the need for more sustainable alternatives. In light of this, this dissertation presents a systematic review on the use of dietary supplements as a strategy for the prevention and treatment of BRD, as, to our knowledge, no study has systematically gathered this data. The objective is to provide evidence of these feeding strategies to mitigate the impacts of the disease on beef cattle production in intensive and semi-intensive systems. The study analyzed data from three scientific databases – PubMed, Scopus, and Web of Science – to compile evidence on the impact of nutrition on the respiratory health of cattle. The results emphasize the potential of dietary supplements in improving immunity and reducing the incidence of BRD. Despite the advancements presented, further studies are still needed on the use of dietary supplements in beef cattle to better understand specific mechanisms of action and application strategies in different settings.
