Description: Ionophores fed to cattle alter the rumen microbiome causing a metabolic shift that underlies improved animal performance. While a majority of the research into mechanisms of action were performed in cattle fed a high-concentrate diet (Thompson et al., 2016), limited information exists detailing their impact in cattle maintained on a high-forage diet. Improved animal performance is especially important in tropical and subtropical regions that are more reliant on forage-based production systems (Cooke et al., 2020). A recent study compared the effects of 3 different feed additives fed to bos indicus bulls receiving a haylage diet (Limede et al., 2021). Results provide new insight into the interplay between ionophore, breed and diet on animal performance.
