ABSTRACT The present study aimed to investigate the effect of Artemisia (Artemisia annua) supplementation as essential oil and powder, in broiler diet on performance and intestinal microflora. One hundred and eighty Cobb 500 broiler chicks assigned to three experimental groups (six replicates with 10 broilers per replicate) were housed in an environment-controlled house. Compared to the control diet, the experimental diets included 0.05 g kg-1 Artemisia essential oil (E1), 0.05 g kg-1 essential oil plus 0.1 g kg-1 powder of Artemisia (E2), respectively. Growth performance was monitored throughout days 14-42. Artemisia supplementation (E1, E2) did not influence growth performance of the chicks. Compared to the C and E1, the chicks from E2 group had a lower count of Enterobacteriaceae in the intestinal and caecal content, both at 35 and at 42 days. The Artemisia supplements did not influence the staphylococci populations from the intestinal content of the chicks (42 days), but in the caecal content samples, this count was lower in E2 (8.836 log10 cfu g-1) than in C (8.876 log10 cfu g-1) and E1 (8.870 log10 cfu g-1). The count of lactobacilli increased in the intestinal and caecal contents of chickens fed the diet supplemented with Artemisia at the 35th and 42nd day. Diet supplementation with A. annua essential oil and powder could be an effective solution in maintaining the proper microflora balance in the chicks’ intestine.
