This study was conducted in the poultry farm of the department Animal Production at the Faculty of Agriculture / University of Kirkuk, for the period from 2018/3/1 to 2018/29.

For 58 days randomly distributed 224 of Japanese quail females to nine treatments (different levels of The study aimed to determine the effect of dietary rationing and the intensity of breeding on the productive characteristics of quail eggs.

The birds were raised in five-stages batteries.

Each floor contains three cages.

The dimensions of the cage (45 cm x 30 cm× 25 cm) length, width and height respectively and coefficient T pilot were as follows:T1: level of standardization 0.0%, breeding density (8) birds 1.68 m2 /bird.

T2: the level of standardization 0.10%, the density of breeding 8)) birds 1.68 m2 /bird .T3: standardization level 0.20%, breeding density (8) birds 1.68 m2 /bird T4: level of standardization 0.0%, breeding density (6) birds 2.25m2 /bird T5: Standardization level 0.10%, breeding density 6) Birds 2.25m2 /bird T 6: level of rationing 0.20%, breeding density 6)) birds 2.25m2 /bird T7: the level of standardization 0.0%, the density of breeding (4) birds 3.37m2 /bird T8: the level of standardization 0.10%, the density of breeding 4)) birds 3.37m2 /bird T9: level of rationing 0.20%, breeding density (4) birds 3.37m2 /bird .Statistical results showed .

There was no significant differences between the treatments in the effect of the density of stocking on the rate of egg production and the mass of eggs and the feed conversion Ratio(FRC) in the rate of weight of eggs decreased in the third treatment compared with the rest of the tretment and a significant increase in the second treatment compared to the other treatment.

The second treatment was decreased in egg production, egg weight and egg mass.

Significant improvement was observed in the second and third treatments in the feed conversion ratio(FRC) compared to the other treatments.

The interaction between feed restriction and stocking intensity was not significant for in the percentage of egg production, egg weight, egg mass, feed consumption rate, and food conversion coefficient feed conversion Ratio (FRC).
