title: Bovine pododermatitis aseptica diffusa (laminitis) aetiology, pathogenesis, treatment and control.
abstract: Pododermatitis aseptica diffusa (laminitis) is a major cause of lameness and discomfort to cattle with resultant economic losses. The disease is a result of multifactorial aetiology most of which is not clearly understood. Feeding readily fermentable carbohydrates to unaccustomed cattle predisposes to the disease. Histamine, lactic acid and endotoxins are believed to be involved. Systemic acidosis, histaminosis and endotoxaemia are thought to produce the pathophysiological characteristics of laminitis. The diagnosis is primarily based on the observation of symmetrical and bilateral lesions in hooves and characteristic lameness affecting all feet. Gross lesions include concavity of the dorsal wall, discolorations in the sole and rotation of the pedal bone. Degenerative changes and arteriosclerosis are constant histological findings in the corium, with chronic thrombi and chronic granulation tissue. The disease may be treated conservatively and by application of cyclo-oxygenase inhibiting non-steroidal anti-inflammatory drugs and prevented or controlled by proper feeding and management practices.
