Abstract:

The prophylactic use of antibiotics as growth promoters in diets for broilers has generated an intensive poultry production and improved feed conversion in the animals. However, resistant bacteria in chicken survive and grow at low doses of antibiotics and may cause an antibiotic-resistant generation. Therefore, researchers are investigating natural alternatives to antibiotics to improve poultry production, such as Origanumâ??s essential oil. To assess the potential effect of native plant species as alternatives, we extracted the essential oils of Origanum syriacum L. and O. ehrenbergii Boiss. by hydrodistillation using Clevenger apparatus and the chemical composition of both species was determined by GC-MS analysis. The antimicrobial activity of serial dilutions of the oils and thirteen (13) antibiotics was in vitro tested against detected microorganisms isolates (E. coli) by growth inhibition and determination of minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). The yields of essential oils reached 8.5% for O. syriacum and 2.4% for O. ehrenbergii. The major compounds identified in both plants were Carvacrol and Thymol. Both essential oils tested showed a very promising potential in inhibiting the growth of tested bacteria comparing to the antibiotics used. These results clearly demonstrate the high and economic potential of using these plants as natural and safe additives to promote food safety and limit the resistance arising from the misuse of antibiotics. Further investigation on the sanitation and hygiene systems applied on the food flow of Lebanese poultry is necessary.
