Abstract

The incidence of cattle lameness at calving is increasing and has been identified at the top priority for cattle welfare R&D. Although many of the environmental risk factors have been identified the systemic mechanisms leading to tissue damage are unknown. We propose that solear lameness at calving is due to consequent changes in metabolism causing the remodelling of the collagenous structures. This, combined with mechanical stresses on the hoof, leads to rupture of the supporting collagenous fibres of the corium and tendons. A major known risk factor is hoof angle. This may be due to an imbalance of tension on the supporting structures, again leading to remodelling and weakening of the fibres. In this study we propose to establish the nature of the changes due to remodelling and correlate them with the loss of mechanical strength leading to the rupture and ultimately lameness.
