Intensive research has focused on the potential of natural growth promoters (NGP) to replace antibiotics. The beneficial effects of NGP are mainly attributed to their potential to promote a beneficial gut microflora which protects the host against pathogens and helps to alleviate periods of stress. Tobias Steiner of Biomin argues that a well-adjusted combination of different strategies will maximise the efficacy of NGP in antibiotic-free feeding systems.
