[Expression of growth dynamic in the structure of periosteal bone in Anas platyrhynchos].
An experimental study of the periosteal bone growth in the mallard from 42 to 154 post hatching days shows: (1) a noticeable time difference in the local biological age of the diaphyseal cortices between various long bones; (2) great differences in their histological structures, at a given individual age, expressing commensurate differences in local growth rates. Those results emphasize the importance of local factors to interpret the typology of the primary (periosteal) bone tissues. Experimental results allow to quantify the relationships between bone tissue typology and the velocity of its radial deposition.
