Potential of plant essential oils and their components in animal agriculture – in vitro studies on antibacterial mode of action
Published:November 9, 2017
Summary
Introduction Plant materials including flowers, roots, bark, leaves, seeds, peel, fruits, and wood can be used to extract aromatic and volatile liquids known as essential oils (EOs) (1–3). These EOs have a long history of use for medical purposes, in perfumes and cosmetics, and as herbs and spices for foods. EOs are considered to be secondary metabolites in plants; secondary metabolites ...
The information is very nice .Poultry farm owners are to be made aware of the use of essential oils which is the need of the present day as synthetics are making harm both to user and the bird or animal .
Very good review of in-vitro studies with essential oils. The in-vitro studies in this review clearly show a potential anti-microbial effect of various essential oils. The subject of this review was in-vitro studies but considering the in-consistent efficacy of essential oils in-vivo, I think there must be some parameters that the in-vitro models do not include like interactions with various feed components, pH, transit time and so on.
It appears that few in-vitro dose-response trials with EO have been carried out or they were left out of this review? It would be very interesting to know the actual concentrations of commercially available EO in the digesta and relate them to the in-vitro dosages applied.
Manufacturers of EO often advertise their EO products having strong anti-microbial effects. This is probably completely true but the active components also kill beneficial bacteria as observed with antibiotic treatments.
