تأثير مستويات مختلفة من الطاقة الممثلة في بعض الصفات الإنتاجية لطائر السمان البياض

Abstract EN

The aims of this study to evaluate effect of five levels of metabolism energy 2700, 2800, 2900, 3000 and 3100 Kcal.

/ kg diet to nutrition females of laying quail and their impact on some qualitative and quantitative characteristics of eggs.

A total of120 birds 8 weeks age divided into five treatments, in each one 4 replication, 6 female for each replication.

This study was expand for 60 days.

The results showed significant difference (p ≤ 0.05) in egg number, egg production percentage H.

D.

(%), egg width (mm), yolk diameter (mm) for T4 and T5, egg weight (g), egg mass (g egg / female) (g eggs / female / day) and yolk percentage (%) for T4, As well as feed conversion ratio (g feed : g eggs), energy conversion ratio (Kcal.: g eggs) (Kcal.: egg), protein conversion ratio (g protein : g eggs) (g protein : egg) and water conversion ratio (ml water : g eggs) for T1 and T2.

Significant effect (p ≤ 0.05) also founded in feed consumption (g diet / female), feed conversion ratio (g feed : egg), and protein consumption (g protein / female) for T1, while water conversion ratio (ml water : egg) for T1, T2 and T3, and for all treatments compare with T5 in water consumption : feed consumption rate.

No significant effect in egg weight : initial female weight rate, egg weight : final female weight rate, egg length (mm), egg shape index, albumen and shell percentage (%), shell thickness (mm), yolk height (mm), yolk index, albumen height (mm), energy consumption (Kcal.

/ female), water consumption (ml water / female), final body weight and weight change (g / female).

The best net return (Iraqi Dinar : g eggs) (Iraqi Dinar : egg) for T4 while the lest for T1, also same as for net return percentage compare with total cost.
