Looking beyond alternatives, we must focus on cost, ingredient selection and dietary nutrient adjustments to fully replace in-feed antibiotics.
In most cases, any discussion regarding replacing in-feed antibiotics revolves around the topic of replacements. Yet, experiences from the European Union reveal that no single additive can fully compensate for the removal of antibiotics from pig and poultry feeds. Not only is a combination of additives is required, but also, a refocus on feed formulation with particular emphasis on ingredient selection and dietary nutrient adjustments. In my opinion, even more important is the issue of animal health and that of overall farm health status (see Figure 1), but this is beyond the scope of this article that focuses on nutritional intervention strategies.
