This study was conducted at poultry farm / collage of Agricultural Engineering Sciences / University of Baghdad from 2/4/2017 to 14/5/2017 to investigate the effect of adding different levels of parsley oil to the diet on broiler growth performance and carcass yield.

A total of 300 one-day-old broiler chicks (308 Ross) were divided in to four treatments with three replicates (25 chick / replicate).

Treatment groups were: T1: control diet without parsley oil, T2: control diet + 150 mg parsley oil/kg diet, T3: control diet + 300 mg parsley oil/kg diet, T4: control diet + 450 Parsley oil.

The results showed that T3 had significantly (P<0.01) increased in the body weight as compared with other treatments for the weeks 3, 4, 5.

Also, T3 group recorded higher body weight gain as compared with T1 and T2 treatments, but no different with T4 treatment.

T3 had greater (P<0.05) total body weight gain as compared with other treatments, while T2, T3 were significantly improved the feed conversion ratio for 4, 5 weeks compared with other treatments.

There was no significant difference between the treatments in the total feed conversion ratio, feed intake, dressing percentage and relative weight of the carcass parts.
