Dietary antibiotics have played an important role in animal production as growth and health promoters. However, the use of most antibiotic growth promoters has been banned in many countries, especially in the European Union, because of public concerns about their residues in the animal products and the development of antibiotics-resistant bacteria. Aromatic plants and essential oils extracts have become more important due to their potential antimicrobial and stimulating effects in the animal digestive system. The aim of this study was to evaluate the effect of mint (Mentha longifolia), basil (Ocimum basilicum), parsley (Petroselinum crispum), dill (Anethum graveolens), coriander (Coriandrum sativum), garlic (Allium sativum) on the carcass characteristics and small intestinal morphology of broiler chickens. 480 one-day old broilers were assigned to eight groups with 3 replicates of 20 birds per pen and fed with a basal diet (control) or basal diet supplemented with 1.5% mint, basil, parsley, dill, coriander, garlic respectively or 0/015% Antibiotic Virginiamycin. There was no difference in carcass characteristics and fat pad and small intestinal length (p>0.05). Villi height was not changed significantly in any segment of small intestine (p>0.05). Effect on villi height to crypt depth ratio and villous height to basal width ratio was significant (p<0.05). It can be concluded that the medicinal and aromatic plants have positive effect on broiler performance.
