Abstract

The present study was designed to investigate the effect of curcumin, anise ground seeds levels and their interactions on growth performance, some carcass traits and economic evaluation of broiler chicken. Two hundred and ninety seven birds were randomly assigned in factorial design (3×3) experiment. Three curcumin levels (0 ,50,100 mg/kg diet) and three anise ground seeds levels (0 ,0.50% and 1% in diet) were used in nine treatments of 33 birds each (three replicates of 11 birds each).During the experiment the body weight and feed intake were measured and consequently, weight gain and feed conversion ratio were calculated. At the end of the experiment, three birds from each group were slaughtered to record carcass parts. Also ,economical evaluation of the diets was calculated in the end of experiment. The results showed that chickens were fed curcumin at level of 100 mg/kg diet achieved higher body weight at 14 days of age and body weight gain during the period of 7-14 days than control and level of 50 mg/kg diet. The addition of anise ground seeds at level of 1% achieved higher feed intake than control and 0,5% level. The addition of 50 mg/kg diet of curcumin and 1% anise ground seeds achieved better feed consumption during the period from 14-21 and 21-28 days of age than other interactions. No significant (P<0.05) effects on feed conversion ratio due to curcumin, anise ground seeds and their interactions. There were significant (P<0.05) effect due to curcumin levels on hart% and left femur t%.
