Thyme (Thymus vulgaris
) is an everygreen herb from the mint family. It has been used for culinary, medicinal, ornamental and folk medicine uses in a variety of different cultures. Thyme is used in fresh and dried form, a whole sprig (a single stem snipped from the plant), and as an essential oil extracted from the plant parts. Volatile oils of thyme are among the main essential oils used in the food industry and in cosmetics as preservatives and antioxidants.
Thyme oil contains important bioactive chemicals which include:
Thyme has an herbaceous and slightly floral aroma. It loses its aroma quickly with heat.
Thyme oil shows potential for improvement of intestinal barrier integrity, antioxidant status as well as evoking an immune response in chickens.
Thyme oil (1 g/kg) proved to be effective in reducing Coliform
counts when it was used to create a spray for the purpose of hygiene improvement.
100 ppm of thyme can help improve body weight and feed conversion ratio in chickens.
