Causes of diarrhoea in lambs during autumn and early winter in an Icelandic flock of sheep
In 2002 intestinal parasites and bacterial infections were studied on the Fossárdalur sheep farm, Eastern Iceland, where for years lambs have suffered from severe diarrhoea in autumn and early winter that some-times has become fatal. Mainly food changes, but sometimes also Giardia duodenalis, were r...
