The effect of immersion and spray of hatching eggs with vitamin c in hatchability and productive performance of quail progeny

Abstract EN

Research was conducted in the fields of animal production department / Collegeof Agriculture and Forestry/ University of Mosul form 3/4/2019 to 22/5/2019 for 49days, to investigate the effect of treating hatching eggs with vitamin C by immersion(Im) and spraying (SP), in the shell thickness and weight, hatchability, productiveperformance, carcass and some blood parameters.

The study include: the initial eggweights at days (5, 10, 15), the shell thickness and weight before and after incubation, The treatments groups were as follows: 1st control, 2nd: the (Im) of eggs with distilledwater, 3rd: (Sp) with water, 4th: (Im)by 5g vit.

Cl, 5th: (Im) with 10g/l, 6th: (Sp)with 5g/l and 7th: (Sp) with 10g /l, duration of (Im) and (Sp) was 2 Min.

After hatching, birdsreared for 49 days.

The results revealed an increase in the loss% of egg weight, hatching% and in the weight of hatching chicks and a decrease in the egg weight% ofthe initial weight, and increase in embryonic mortality% for (Im) by 10g/l.

Decrease inbody weight and feed consumption in Vit.

C treatments with improvement in feedconversion and production index for (Im) (5, 10) g/l and high mortality% at (Im) 10g/L.

Significant superiority in the dressing in 10 g/l and the chest% for Vit.

Ctreatments, significant decrease in abdominal fat in (Im)at a 10 g /l at 49 days.

Adecrease in serum glucose, globin and triglycerides to spray 5g vitC /l
