The present invention related to an use of bone protein extracts of poultry for bone graft. It main content is to conduct several biocompatibility experiments to confirm the non-toxic and non-allergenic properties of the bone protein extracts which produced by following predetermined steps. So the bone protein extracts can be added into bone graft as the component of it.一種家禽類骨蛋白萃取物用於骨填補材的用途，係對於依預定步驟製備的家禽類骨蛋白萃取物進行生物相容性試驗，以確認其對於生物體無毒性與致敏性風險，而能將該骨蛋白萃取物作為組成成份之一加入於骨填補材的用途。
