survey of white line disease in racehorse population in the North of Iran [Gonbad]

ABSTRACT

During summer 2000 and 2001, 482 racehorses kept in Gonbad in the North of Iran sere studied for white line disease. The survey was conducted when horses were being shoed by farriers. The horses that still exhibited damaged white line after regular trimming were diagnosed as having white line disease. The factors recorded were age, sex, number of diseased hooves, number of lesions by region over the bearing border of the hoof. The percentage of total diseased horses was 20.7% [100 horses], with incidence increasing significantly with age [P=0.00 1]. The occurrence of white line disease was independent of sex [P>0.05] and was observed more frequently in the fore- than in the hindhoof [P<0.05] and developed more frequently at the toe than at any other region of the forehoof-bearing border [P<0.05]
