This study was conducted to investigate the effects of using different levels of coriander oil on carcass traits, blood biochemical and immunity parameters of broilers.In this study that started 1 day following until 42 days, at first 375one day old broiler chicks were divided to5 groups and five replicates of 15 chicks each. Experimental groups included T1, control group with no coriander oil supplementation, T2,T3, T4,and T5 received 0.75%,1%, 1.5%, and 2% coriander oil. The results showed that the use of different levels of coriander oil has significant effects on performances and carcass traits of broilers (P<0.05). The highest percent of breast and thigh were observed in group5 and the lowest percent of abdominal fatwas observed in group 4. The results evidence that the using of coriander oilin broiler feeds have significantly effects on performance and blood biochemical andwithout having any significantly effects on immunity parameters.
