Comparative osteometric differences in humerus of bari Goat and Dumbi Sheep

Morphological studies were conducted on the Humerus of 60 clinically healthy animals (30 Bari goat and 30 Dumbi sheep) of both sexes, slaughtered at Tandojam and Tando Allahyar abattoirs. For comparative study, animals were divided in three age groups viz., lambs/kids (6-9 months), yearlings (13-21 months) and adult (21-24 months). The estimated age was determined through dental formula, whereas, the body weight was obtained using spring balance. For collection and preparation of specimen standard procedures were adopted. The weight (Mean± SEM) of right and left humerus of three age groups of Bari goat and Dumbi sheep is found to be 26.66±0.23, 34.06±0.33, 46.44±0.44, 31.29±0.83, 47.20±1.27, 53.62±0.66, 26.54±0.34g, 34.87±0.40, 46.47±2.64, 31.32±0.83, 47.56±0.60 and 53.57±0.53 g, respectively. Statistical analysis revealed significant difference (p 0.05) in between and among the adult groups of both species. The Bari goat possess relatively longer humerus than those of the Dumbi sheep. Mean values for breadth of proximal end (Bpe), breadth of distal end (Bde) and circumference of right and left humerus from three age groups of Bari goat and Dumbi sheep showed statistical differences between the age groups but no statistical difference was noted among two species and sexes.   Key words: Osteometric, differences, humerus, Bari goat, Dumbi sheep.
