Outbreaks of dermatophilosis in nine herds of dairy cattle in Israel were studied retrospectively. The outbreaks might have been associated with the exposure of the animals to intense showering during the spring and summer months of May to October, in addition to calving and postcalving stress. The acute exudative form of dermatophilosis occurred in the first‐calving cows during the six weeks after they calved. The morbidity rate ranged from 10.0 to 66.6 per cent and the period of morbidity ranged from eight to 19 days. Mortality or culling occurred in four of the herds and ranged from 1.6 to 17.1 per cent. The disease also resulted in a gradual loss of condition, a decrease in milk production and marked increases in the somatic cell counts in milk.
