Bottom Line: Complementarily, the lengths of medial and lateral metapodials in these species were compared.Afterwards, each bone was scanned and the same lengths were digitally measured twice using commercial software.In goats, the lateral length of both metacarpals and metatarsals was significantly higher than medial length (P < 0.05); in sheep the lateral length was significantly higher compared to the medial one only in metatarsal bones (P < 0.05).

ABSTRACT
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. Complementarily, the lengths of medial and lateral metapodials in these species were compared. The limbs of 30 ewes and 30 goats were used. After preparation, the lateral and medial length of the metacarpals and metatarsals were measured twice with a caliper. Afterwards, each bone was scanned and the same lengths were digitally measured twice using commercial software. 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 (P < 0.05). All lengths measured with the caliper were significantly higher compared to those measured with the 2-dimensional method (P < 0.05). In goats, the lateral length of both metacarpals and metatarsals was significantly higher than medial length (P < 0.05); in sheep the lateral length was significantly higher compared to the medial one only in metatarsal bones (P < 0.05). 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.

Mentions: The distal extremities of the limbs from 30 ewes and 30 goats (median age 3.7 years) were collected from a slaughterhouse and immediately identified (fore-hind limb) and grouped according to the animal. Consequently, the metapodials were prepared for study by successive boiling, cleaning, degreasing, washing, and drying. At first, the lateral length (LL) and medial length (ML) (Figure 1) of the metacarpals and metatarsals were measured with the aid of caliper (accuracy 0.1 mm) twice by the same researcher (T.C). The variable LL represented the distance from the lateral proximal end of the metapodial bone to the abaxial border of the lateral condyle. Accordingly, the ML represented the distance from the medial proximal end of the metapodial bone to the abaxial border of the medial condyle. Afterwards, each bone was scanned on a scanner (HP scanjet 3670) in order to obtain a digital image of the bone; the same lengths were digitally measured twice by the same person using GIMP 2.0 (GNU Image Manipulation Program) software. Based on these data, the average length for each bone and the absolute relative deviation between the two measurements [/(measurement1 − measurement2)∗100/measurement1/] of the same bone for each method were calculated.
