Ovine dermatophilosis in young sheep associated with the grazing of Brassica SPP crops

The occurrence of dermatophilosis in five month old lambs associated with the grazing of Brassica spp. Crops is reported on four farms. The prevalence of the disease varied from 3% to 45% within affected flocks. An additional finding was the occurrence of nervous signs in a small number of more severely affected lambs, characterised by a sudden lowering of the hindquarters. The association between dermatophilosis and the grazing of Brassica spp. crops is discussed.
