During 1975 a study was carried out on 4 dairy herds (mainly Holstein-Friesians) in which 20-60% of the milking cows had fibrous teat end lesions with no obvious cause. Laboratory results for each herd are given on gross pathology of the teat, histopathology, virus isolation and serology, together with history and clinical observations. A viral etiology was suspected because it seemed that the lesion spread through the herd; however, this was not confirmed by the results. Teat dips were also another possible factor, but again this was not confirmed. Evaluation of milking equipment did not reveal any constant abnormality. It was thought that teat end trauma produced by over-milking may have been a causative factor.
