ترجمة الملخص

The research was carried out on 800 eggs ,which were obtained from broiler breeder flock (Ross crossbred) age 7 -8 months . the eggs sorted into two weights (45-55)and (56 -65) g . After evaluating its according standard characters, the sterilization procedures were applied on it , then the eggs divided into 4 groups ,eachgroup from them consist of100 eggs , which were stored according to their weight for different periods of time ,4,7,10 and 14 days, its sambaed as(A,B,C,D)consequent .After that the eggs put in incubator from model (Pterseem) then moved toHatcher machine, the percentage of fertilization was accounted during incubation period which was 18 days . the percentage of infertile eggs, also, was accounted during the same period . After hatching eggs ,the percentage of fertile eggs had accounted from total number for every category from experience of eggs , and also the percentage of dead embryos had accounted .The hatching chicksoutput from every categoryhad reared up to42 days ,all conditions of placement , rearing and feeding were the same for all birds .Results showed that there were significant effect for the storage period of hatching eggs in hatching factors ,where those factors decreased with increasing storage period while, weight of hatching egg had no significant effect on the percentage of fertilization and hatching ,and the period of hatching eggs storage had no significant effect on the chicks weight, when hatching egg weight increase the hatching chicks weight increase .In addition to that ,the results showed that the presence of significant effect of the storage period on the average of final live body weight of the birds, where the increasing of the storage period length led to a significant decrease in the birds weight ,while the hatching eggs had no effect on the bird in later age. As well as ,the storage period had a significant effect on the feed efficiency for the chicks,the hatching egg weight had no significant effect on the feed efficiency , as well as , the hatching egg weight had no significanteffect on the mortality rate. but the length of the storage period had an effect on that , were the mortality rate increases with the increase of the storage period length
