Description
INTRODUCTION Antibiotics are commonly fed to animals in livestock production systems to prevent disease and metabolic disorders, as well as to improve feed efficiency. However, in recent years, public concern over the routine use of antibiotics in livestock has increased due to the emergence of antibiotic resistant bacteria that may represent a risk to human health. Consequently, considerable effort has been devoted towards developing alternatives to antibiotics. Plant extracts have been shown to offer a unique opportunity in this regard (Wallace, 2004) because many plants produce secondary metabolites, such as saponins and tannins, which have antimicrobial properties. The beneficial effects of essential oils on farm animals include the activation of feed intake and secretion of digestive juices, immune stimulation, and anti-bacterial, coccidiostatic, antiviral and antioxidant properties (Wenk, 2003). Contrary to their name, essential oils are not true oils (i.e., lipids), but are commonly derived from the components responsible for fragrance, or Quinta essentia, of plants. Essential oils are considered safe for human and animal consumption, and are categorized as generally recognized as safe (GRAS; FDA, 2004) in the USA.
