A study carried out in quail’s field Department of Animal production/Agriculture Collage/Tikrit University.

72 females quail Coturnix japonica at age (48weeks) with period 16 / 3 to 11/5/2014 (8weeks) for study adding phytase enzyme to Quails ration and effect on some productive and eggs Qualities traits.

The birds randomly distributed to three treatments, every treatment included three replicates (8 females quail each replicate).

The birds were fed stander ration without phytase supplement (T1 control treatment) while treatments 2nd (T2) and 3rd (T3) fed stander ration and added phytase with concentration (250 and 500 gram/ ton feed).

The results appears higher significant(P < 0.05) in eggs production hen day(H.D), eggs production cumulative, eggs weight, eggs mass and feed conversion ratio for(T2) and (T3) compared with (T1) and higher significant(P < 0.05) in egg white weight% for(T1) and (T3) compared with (T2) which recorded lowest white %.

No significant showed among different experimental treatments in mean of feed consumption, egg shell thickness, shape index, shell %, high, diameter and index for white, Huagh unit, high, diameter, index and weight % for yolk.
