Abstract

Ionophores are naturally occurring polyether antibiotics that disrupt ion balance in bacterial cells by selectively transporting metal ions across lipid membranes, primarily affecting Gram-positive bacteria in the rumen. The use of ionophores as a feed additive in sustainable beef cattle production offers a promising and innovative solution to key challenges in livestock farming, such as enhancing feed efficiency, lowering methane emissions, and promoting animal health. However, their use is surrounded by several misconceptions, which can lead to confusion among consumers, policymakers, and even within the agricultural industry. This review aims to assess the advantages, disadvantages, and safety aspects of ionophore use in beef cattle production. Published literature related to ionophores in cattle diets and their effects was collected from PubMed, ScientificGate, Google Scholar, ResearchGate and Academia. Ionophores have been reported to reduce rumen disorders like bloat and acidosis. Ionophores reduce methane emissions by altering ruminal fermentation to favor propionate production over acetate and butyrate. Ionophores may exert varying effects depending on the animal, diet, and type and dose of ionophore administered. Studies suggest limited cross-resistance to medically important antibiotics. As ionophores are metabolized and excreted rapidly, it is expected to have minimal adverse effects on human health.Overall, ionophores are promising feed additives that may play a significant role in sustainable beef cattle production, offering producers the opportunity to improve profitability while reducing environmental risks.
