A study was conducted to investigate the effect of supplementing drinking water with different levels of vitamin AD3E alone or with vitamin C on the productive performance of broiler chicks.

A total number of 900 day old hatchcd broiler hybrid (Ross) chicks were allocated randomly to six dietary treatments in three replicates of 50 chicks/rcplicatc.

The treatments were: control, 1.25ml/L AD3EI.25 ,ml/LAD3E + 15g vit.

C, 2.5ml/L AD3E+ 15g vit.C, 3.75ml/L ADaE+15g C and 5ml/L AD3E +15g vit.

C/L.

The results indicated that the average body weight and ffied conversion ratio of chicks supplemented with vitamins AD3E alone or with vitamin C in the drinking water were significantly (P < 0.05) higher than that of the control group.

Furthermore, supplementing broiler chicks with extra amounts of vitamins AD3E and vitamin C significantly (P <0.05) increased calcium (Ca) and phosphorus (P) blood levels compared with those of the control group.
