This study was done on 54 sheep and 54 goats at different farms in Kalyobia governorate to estimate the age of the animals through radiographic images. Radiographic images of the humerus bone in both sheep and goat were shot at different ages. The length and radiographic characters of the humerus bones were varied in species and age advances. The humerus lengths were increased steadily from (9.03±0.05) centimeter (cm) and (11.22±0.07 cm) at the age of 2 months in sheep and goat respectively. The humerus length increased till reached (18.10± 0.09 cm) and (17.87± 0.04 cm) at the age of 48 months in sheep and goat respectively. The growth plate opened at the age of 2-8 months then ossification begin and complete closure of the epiphyseal plates appeared at the age of 42-48 months in sheep while in goat the complete epiphyseal closure occurred at the age of 36-42 months.
