چکیده مقاله:

The current study was carried out at the Radhwaniyah station which belonged to Agricultural Research Department of the Ministry of Agriculture for the years 2000 to 2001, Which included analysis of data of local Awassi sheep, Assaf and Cross Assaf (local Awassi× Assaf). Records included both weight at birth, weaning and age 6, 9, and 12 months for the three genetic groups above. The study investigated the effect of the genetic group on the weight of the lambs at various age stages and then calculated the effects of the heterosis resulting from the crossing of local Awassi sheep with the Assaf sheep for the weights in the ages from birth until the age of one year. The results showed that the genetic group had a significant effect (p˂0.01) on the all studied traits ,and The effects of heterosis were not significant for all studied traits, but were close to previous studies, with 10.36%, 12.20%, 5.80%, 6.49% and 4.92% for weight at birth, weight at weaning, weight at age 6 Months, weight 9 months and weight 12 months, respectively.
