Abstract

In order to describe papillomatous digital dermatitis (PDD), and to determine risk factors for highly affected dairies, data from 37 southern California dairies with >5% of cows affected (highly affected dairies, cases) were compared with those from 20 dairies with 5.5% of cows affected (controls). Information on dairy environment, management and PDD occurrence was obtained from dairy managers, veterinarians and hooftrimmers, and by direct measurement.
