Viability of Local and Turkish AWASSI sheep lambs where compared at weaning, 6, 9, and 12 months of age in order to study the effects of the parents breed, sex, birth type,age and interaction among them for the years 2009, 2010, 2011, sheep records of Agriculture research state board – sheep station in Baghdad, were analyzed, which its account were 1218, 1199, 1190, 1163 at weaning, 6, 9, 12 months of age respectively . Study result appeared that the parents breed was significant (p > 0.01), to the Turkish lambs from the weaning to one year of age. while the parents age were significant (p > 0.05) at 6, 9 months and high significant (p > 0.01) for lambs livability at 12 months of age, while parents sex and birth type effects were not significant at lambs livability at any period from weaning to one year of age . Highest livability of lambs were for parents of 4 years old that reached 90.738%, 89.976%, 89.685%, and 88.887% while the lowest lambs livability were for parents of 8 years old that reached 77.777%, 76.736%, 76.736%, 61.111 % at weaning, 6, 9, and 12 months of lambs age respectively. Interaction between parents breed and age was significant (p > 0.05), for lambs livability, only at the age of 12 months, while all the other interactions were not significant.
