Abstract

The experiment was conducted on 1080 fertile eggs (average 62 grams weight) collected from AL-SHROUK breeder farms of 34 weeks old breeding flock.  This eggs were randomly divided into 3 groups of 360 eggs according to storage period (7, 14 and 21 days) and subdivide into 4 groups of 90 eggs each according to warming treatments (0, 4, 8 and 12 hours) at 37.5°C, after the warming treatments eggs placed for two hours in setter hall and back into cooler operating at 16 – 18oC and 60 – 80% relative humidity until end of all storage time. Egg storage until 7 days showed the best significantly values for fertile eggs, fertility%, hatchability%, hatchability of fertile eggs%, average chick weight. However storage until 21 days showed the highest significantly number of un-hatched eggs and showed the highest number of total embryonic morality and weight losses. Pre-hating at 4 hours showed the highest significantly values for hatchability percentage and hatchability of fertile eggs percentage but Pre-hating at 12 hours showed the highest significantly number of un-hatched eggs and showed the highest number of total embryonic morality without any significant effect. Interaction between storage periods and pre-heating treatments showed significantly effect on hatchability percentage, hatchability of fertile eggs percentage, chick weight, un-hatched egg, embryonic mortality, percentages of chick weight before and after storage, and dead chicks.
