Many of the issues that lead to lameness in dairy cows begin with heifers either before calving or in the first lactation, Gloucester vet Roger Blowey said at a recent meeting in Cookstown.

At the event organised by Provita, Blowey explained that the corium in the inside of the hoof acts as support tissue which carries blood and is needed for formation of the horn (outer surface of the hoof), as well as bones in the foot.
