At present, even after mechanization of agriculture, 55 per cent of the total cultivable area is ploughed by draught animals. Yet, draughtability traits are the most neglected traits. Hence, this study was undertaken to assess the draughtability potential of Umblachery breed of cattle besides recording phenotypic performance and to associate the polymorphism in six candidate genes viz. Angiotensin I-converting enzyme (ACE), Adrenergic beta 2 receptor (ADRB2), Bradykinin beta 2 receptor (BDKRB2), Glutathione peroxidase 1 (GPX-1), Insulin-like growth factor-1 (IGF-1) and Vasculo endothelial factor alpha (VEGFA) with draughtability traits.enVeterinary ScienceThesis
