The effect of feeding broiler chicks on diets containing antibiotic and different levels of anise oil as feed additive on productive performance, carcass characteristics and economical efficiency were studied. A total of two hundred and fifty one-day old, unsexed (Ross-308) broiler chicks were randomly divided into five experimental groups. Each group was further subdivided into five replicates ten chicks per pen in complete randomized design. The birds were fed with two basal diets (starter and finisher) to form five experimental groups. The first group (A) fed on basal diet without feed additives (negative control diet), the second group (B) fed on basal diet with 0.1% added antibiotic Neomycine sulphate (positive control diet). The other groups (C), (D) and (E) were fed on basal diet supplemented with anise oil (Pimpinella anisum) at levels (150, 250 and 400 ppm) respectively. The experimental diets were fed for 6-weeks duration. Health of the stock and performance parameters were recorded. At the end of the experiment, the birds were slaughtered, dressed then the different parameters and economical evaluation. The results showed that, the diet with 400ppm anise oil had significantly (P<0.05) heaviest body weight gain, highest feed intake, best feed conversion ratio, highest dressing percentage with highest percentages of commercial cuts (breast drumstick and thigh). In addition, the inclusion of anise oil in broiler diets showed significantly (P<0.05) the most tender breast and thigh meat and higher liver and gizzard percentages compared to both antibiotic and control diets. The birds fed the antibiotic and control diets produced significantly (P<0.05) highest abdominal fat percentage. The mortality rate did not significantly (P>0.05) affected by the experimental treatments. The highest profitability ratio (1.85) was recorded by the diet with 400ppm anise oil in broiler diet.
