microstructure of domestic herbivores is still not completely
understood. Indeed, works focused on the bone histology of numerous
Mammalian species frequently led to misunderstandings because of the
high number of variations such as the kind of bone, section
orientation, species, breed and age. Moreover, attempts to identify the
species in archaeozoological studies by a mere qualitative approach
have not been encouraging and in recent years quantitative methods,
based on image processing and statistical analysis, have appeared. The
present study was undertaken to determine whether morphometrical and
morphological differences exist in the compact bone structure of the
femur and humerus between horses and cows. Measurements such as area,
perimeter, minimum and maximum diameter of osteons and Haversian canals
as well as the osteonal density were carried out on cross sections of
eight humeri and eight femurs of the two herbivores investigated. In
agreement with other authors, the qualitative investigation confirmed
that the compact bone of horses and cows can be classified as dense
Haversian tissue. Osteons of the horse were more numerous and composed
of a higher number of well-defined lamellae when compared with the cow.
Diameter, perimeter and area of osteons and Haversian canals were
always higher in horses than in cows and this pattern could be related
to the different locomotor behaviour of these animals.
