Effect of aloe Vera and vitamin C on productive performance and qualities trails of eggs in Japanese laying quails

Abstract EN

This study was carried out in the Animal farm, department of Animal Resource, College of Agriculture, University of Tikrit during the period from 26 feb.

2013 to 26 apr.

2013, to investigating effect of Aloe vera leafs gel and Vitamin C which added to drinking water on the productive performance of Japanese female quails (Coturnix coturnix japonica) at 25 weeks of age.

Water and feed were provided ad libitum during the experimental period.

60 female quails reared in cages and distributed in to four Treatments, each group contained 15 birds each group divided into 3 Replicates, each replicate contained 5 birds.

(T1) is control, (T2) contained (100 ml / liter water) Aloe vera, (T3) contained (250mg / liter) Vitamin C and (T4) contained (100 ml / liter water) Aloe vera with (250mg/liter) Vitamin C.

The effects of Treatments in mean total periods on feed consumption, feed efficiency, body weight, egg weight, shell egg %, albumen height, albumen index, yolk diameter, shell egg thickness, egg shape index and haugh unit were no significant (P<0.05).

The effect of Aloe vera at (100 ml/liter water) were found significant (P<0.05) on total cumulative egg number, Hen Day egg production(H.

D) and albumin diameter compared to control.

The effect of Vitamin C at (250 mg/liter water) showed significant (P < 0.05) on egg mass and yolk % compared to control and also on yolk / albumin % compared to T4.

The effect of (100 ml/liter water) Aloe vera with (250mg) Vitamin C together on albumin % and yolk height showed significant (P < 0.

05) compared when used Vitamin C at (250 mg/liter water) and yolk height compared to control.

Based on the findings of the present study, it was concluded treatment that contained (100 ml / liter water) of Aloe vera with (250mg / liter water) of Vitamin C was effective in improving performance of Japanese laying quail.
