An outbreak of narasin poisoning in swine is described. The diagnosis was based on the history, clinical-pathological findings, the reproduction of the disease by the administration of the feed originally given to the animals and by chemical analysis which showed doses sufficiently high to cause poisoning. Inspite that the clinical-pathological picture of the natural and experimental poisoning was of the same nature, there were some differences. In the natural outbreak lethality was high, but in the experiments none of the animals died. In the natural cases besides the lesions in the muscles, also lesions of the heart muscle fibres were seen, not detected in the esperimental animals. It is suggested that these differences could be due to the stress to which the animals were submitted in the piggery by the great number of animals per box, whereas the experimental animals were kept individually.
