Abstract EN

This study was conducted in the farm of poultry-Animal production department of the faculty of Agriculture University of Kirkuk during the period from15/1/2017 to 18/2/2017 , The aim of this experiment was to determine the effect of adding probiotic and prebiotic in growth diets contain and free from animal protein on the production performance and carcass quality for males and females Japanese quail.

(240) Japanese quail un sexed (one day old) which has been fed collectively for 10 days and distributed randomly to 8 treatments(30 bird/treatment) by 5 replicates for each treatment (6)birds per cage (Replicate is one of battery cages with dimensions 40*30*20 cm) the experiment period was 10-45 days .

Birds were fed the following dietary treatments T1 (control diet ), T2(control diet + 0.10% probiotic ) , T3(control diet+ 0.10% prebiotic ) , T4 (control diet +0.10% probiotic+0.10% prebiotic ) , T5(control diet with out animal protein trate concen) , T6(control treatment+ 0.10% probiotic ) , T7(control diet+ 0.10% prebiotic ) , T8(control diet +0.10% probiotic +0.10% prebiotic ) .

The results showed that no significant (P≤0.05) differences were found in weight gain, while differences were significant in the average body weight ,the T5 was significantly (P≤0.05) higher than T1 , and in feed intake average T2 was significantly (P≤0.05) exceed over T1 and for the in feed conversion ratio average there was no significant differences between T1,T2,T3,T4 or between T8, T5, T6, T7 and T8 was significantly (P≤0.05) was better than T1, T2, T3, T4.There were no significant differences in the average of the carcass weight and the percentage weight of the wings between treatments .

The T2 was significantly (P≤0.05) better than T1 and T6 for the percentage weight of the breast , While T1 was significantly (P≤0.05) heavier than T5 in the thigh percentage weight .The T4 and T5 were significantly (P≤0.05) bigger than T1 and T8 in the back percentage weight , While the T1 ,T5 and T6 were significantly higher than another treatments in the average of the neck percentage weight .

No significant differences in the average of the heart and liver percentage weight between the treatments .

The percentage weight of the gizzard was significantly (P≤0.05) higher for T1 than T5 and T7.

The intestinal percentage weight for the control treatment (T1) was higher than all another treatments .

On the other hand the percentage weight for the testes was higher significantly (P≤0.05) when compared that with the T2, T4, T6,T7 and T8 .

The value of the percentage weight of the ovary was for the females bird of the T2 were significantly (P≤0.05) higher than T5, T6, T7 and T8 .No significant differences in thepercentage weight of the stomach and oviduct .The average of the pancreas percentage weight for the T1 and T4 birds were significantly higher than T5 birds.
