title: A study of foot disease of dairy cattle in quebec.
abstract: A 12 month survey of the different diseases of the digital region of dairy cattle was conducted in the province of Quebec in order to determine the relation between the frequency of the main digital lesions and different factors involved.Sole ulcer, white zone disease and erosion of the bulb represented 88.6% of all the lesions. The majority of the cases were recorded during the pasture season. An initial peak of prevalence was found in two year old heifers but cows were mainly affected between the ages of five to eight years. Sixty-six percent of the lesions appeared during the first three months of lactation.
