A total of 1800 broiler breeder , Ross 308 at 47 wks old , hatching eggs .Were used in the present study .
Eggs were randomly distributed into 12 experimental treatments ,150 eggs pretreatment groups .
The treatment groups were as follows : T1 treatment without pre-incubation + 4 days eggs storage period T2 treatment without pre-incubation + 8 days eggs storage period T3 treatment without pre-incubation + 12 days eggs storage period T4 treatment 4 hours pre-incubation + 4 days eggs storage period T5 treatment 4 hours pre-incubation + 8 days eggs storage period T6 treatment 4 hours pre-incubation + 12 days eggs storage period T7 treatment 8 hours pre-incubation + 4 days eggs storage period T8 treatment 8 hours pre-incubation + 8 days eggs storage period T9 treatment 8 hours pre-incubation + 12 days eggs storage period T10 treatment 12 hours pre-incubation + 4 days eggs storage period.
T11 treatment 12 hours pre-incubation +8 days eggs storage period T12 treatment 12 hours pre-incubation + 12 days eggs storage period.
Experimental parameters measured included : Fertility , hatchability percentage from the total incubated eggs and from fertile eggs , hatching chicks length , weekly embryonic mortality ,piped eggs and quality evaluation of navel for hatching chicks .
The results of this study showed a significant increase (P <0.05) in the rate of early embryonic mortality of the treatment which was pre- incubated for 8 hours and stored for 12 days compared to the treatment that was unpre-incubated and stored for 4 days, medium embryonic mortality increased to a treatment which was pre-incubated for 8 hours and stored for 12 days compared to the treatment that was pre-incubated for 8 hours and was stored for 4 days , the rate of piped eggs was significantly (P<0.05) increased to the treatment 4 hours pre-incubated x 12 days storage compared to most others treatments.
The percentage of hatched chicks its have the navel type A significantly (P<0.05) increased for the treatment 4 hours × 4 days compared to the treatment 12 hour × 12 days , while significantly (P<0.05) decrease the percentage of hatched chicks type navel B for treatment 0 hour × 4 days compared to the treatment 12 hour × 12 days , either quality type C It has significantly (P<0.05) decreased for both treatments 4 hour ×4 days and 4 hour ×8 days compared to the treatment 12 hour × 12 days
