Postbiotics-metabolites produced by probiotics during fermentation-are fast emerging as a game-changer in animal feed. Unlike probiotics, which rely on live bacteria, postbiotics provide greater stability, consistent efficacy, and longer shelf life, making them easier to integrate into feed systems. With global regulatory bodies tightening restrictions on antibiotics in livestock, postbiotics are rapidly becoming the preferred functional feed additive in poultry, swine, ruminants, and aquaculture.
