In the last years there has been substantial interest on the use of aromatic herbs and essential oils as feed additives in animal nutrition. Significant antimicrobial effects of several essential oils and compounds against gut organisms in farm animals have been shown. Specific Escherichia coli strains could be controlled by in-feed application of carvacrol-rich essential oils, and the effect of some essential oil components against Clostridium perfringens and necrotic enteritis was confirmed in poultry. In ruminants, an improvement of the digestion was observed. Aromatic plants and essential oil compounds improve stability and palatability of animal feed and improved shelf-life and quality of animal products. The ‘growth-promoting effect’ of essential oils is not as evident. Nonetheless, the overall efficacy of essential oils and aromatic herbs, especially their impact on the health status and benefit of animals and humans (via the food chain) is encouraging further research and development in this field.
