Summary The Age Dependent Development of the Long Bones Diaphyses by New Zealand Rabbits and Chinchilla‐Bastard‐Experimental‐Rabbits The age dependent development of the long bones' diaphyses (humerus, os femoris and os tibiofibulare) was examined macroscopically, morphometrically and histologically using 15 White NewZealand Rabbits (TO) and 15 Chinchilla‐Bastard‐Experimental‐Rabbits (Chbb) in 5 different age groups. The main growth of bone occurs in the first three months of life. The remodelling from juvenile to adult bone began in the period from the 4 th – 12 th week. The different bones show various characteristic remodelling zones for each localization. Until the 12 th week the resorption of juvenile bundled bone predominates. Afterwards an increasing bone formation by osteonal bone can be observed. The bone growth is terminated between the 17 th and 33 rd week. The os tibiofibulare in both breeds represents the major part of the compact bone area on the whole cross‐section area. Principally the bone‐remodelling process proceeds equally in both breeds. Breed dependent differences in the adult bone are seen in the construction of the circumferential lamellae. These are formed considerably more irregularly by the Chbb‐rabbits than by the WN‐rabbits.
