This research aims to study the effect of storing period of propagation eggs for (4-7-10-14) days, and the weight (two groups) on Some germination characteristics of Broiler (Ross crossbrid). The experiment was carried out in Broiler breeding house in Homs 800 Ross crossbrid eggs were used to study the effect of storage period, and weight on propagation, hatchability and weights of chicks. The results showed that increase of the storage period affects the propagation and hatchability significantly. The propagation ratio decreased due to storage period (4-7-10-14) by (8,10,16,30%) respectively, and the hatchability decreased by (91.3,86.67,78.57,67.14%) respectively. The storage period affected on the average of chicks weights upon the same group negatively. On the other hand, The eggs weight hasn't an effect on the propagation and hatchability indicators. However, it affected the chicks weights positively, where the average chicks weights of the first group reached to (35)g .while the average chicks weights of the second group reached to (42)g

Key word: Ross crossbrid - storage time - propagation - hatchability.
