Abstract
Antibiotics have been used for decades in poultry diet to reduce disease infections and improve their productive performance, This may lead to the emergence of antibiotic-resistant bacterial strains and the accumulation of these antibiotics residues in animal products that have negative effects on human health, This prompted organizations to attend their use in diets mixtures and the trend towards commercial diets additives of plant origin, including Medicinal plants and their essential oils ,It has antimicrobial properties because it contains many active compounds such as Thymol and Eugenol. In addition, medicinal plants contain other biological components such as phenolic compounds, tannins, and organic acids such as mineral salts, vitamins, and enzymes. Medicinal plant oils also contain a high percentage of unsaturated fatty acids that increase the efficiency of absorption and metabolism of nutrients present in the diet, this in turn, leads to improved production traits represented by live body weight, weight gain, feed consumed, and the feed conversion plant.
