Abstract: This work was done on 108 sheep and goat at different farms in Kalyobia governorate. Radiographic images
of the tibia bone in both ram and buck was shot at different ages. The radiographic images of the tibia showed
radiolucent appearance in the epiphyseal plate at which no ossification occurred and the epiphyseal plate opened at age of
2-10 months in sheep and goat. While the partial union appeared at the age of 12-18 months and 18-24 months in sheep
and goats respectively. The total union occurred between the epiphysis and diaphysis at age of 30-36 months and 28-30
months in sheep and goats respectively. The complete closure of the growth or epiphyseal plate of the tibia appeared in
the radiographic images as complete union between the epiphysis and diaphysis appeared at age of (42-48) months and
36-42 months in sheep and goats respectively.
