This study was conducted at poultry farm, Department of Animal production, College of Agriculture, University of Basrah to investigate the effect of colouring diets in production performance and some physiological traits from 15/10/2015 to 18/11/2015 two hundred and fourty one–day of broiler chicks were randomly distributed.

The four experimental treatments were feed on four different colour diets each treatment had three replicate (20 birds/ per replicate).

The first treatment (T1) as a control natural color diets, T2, T3, T4, 2g of yellow, red and green pigments were disolved in 10 ml distalled water/ kg diet respectively.

Rusult indicated that there was a significant improvement (p<0.05) in final body weight and body weight gain and production index in green color diets and feed conversition ratio had lower significantly (p<0.05) in the some treatment as compared with others.

The result showed a significant increase (p<0.05) in dressing and breast percentage, red blood cells, Hb, pcv, total protein and glucose in green diet treatment compared with others.
