![]() The commonest tool to measure the bones in terms of longitudinal dimensions is the caliper. The previous scientists suggested that the asymmetry observed between the lateral and medial metacarpals and metatarsals of the bovines could be useful for studies on digit function and on the predisposition of cattle to claw disorders. Additionally, a debate has arisen regarding the contribution of the metapodials in the lameness of the artiodactyls. The metapodial bones of sheep and goat have been used in many studies relating to various scope from zooarchaeology to animal biology and pathology. Osteological examination of the excavated bones is very important in terms of identification and study of animal evolution. The knowledge of the anatomical differences of the bones may help to elucidate the function and malfunction of body regions such as the limbs. The morphological variability of domestic and wild mammals is expressed to a great extent on the skeletal structures. Quantitative data of the animal skeleton are extensively used in many biomedical disciplines in order to obtain information of their biology and pathology. In conclusion, the 2-dimensional method is more accurate for the measurement of the metapodials’ length than the caliper and there is asymmetry between the medial and lateral metapodials in these species. In goats, the lateral length of both metacarpals and metatarsals was significantly higher than medial length ( ) in sheep the lateral length was significantly higher compared to the medial one only in metatarsal bones ( ). All lengths measured with the caliper were significantly higher compared to those measured with the 2-dimensional method ( ). Data analysis revealed strong linear relationship between the two methods but the absolute relative deviation of the measurements with the caliper was significantly higher than those with the 2-dimensional method ( ). Afterwards, each bone was scanned and the same lengths were digitally measured twice using commercial software. After preparation, the lateral and medial length of the metacarpals and metatarsals were measured twice with a caliper. ![]() The limbs of 30 ewes and 30 goats were used. Complementarily, the lengths of medial and lateral metapodials in these species were compared. The objective of this study was to compare the metapodial lengths of sheep and goats measured with a caliper with those measured using a 2-dimensional digital method.
