A familial progressive muscular weakness is described in a herd of pietrain pigs. The onset of disease was at two to three weeks of age taking the form of a muscular tremor when the piglets were standing. An impaired gait followed and by 12 weeks of age the pigs had become permanently recumbent. The observed incidence of the syndrome and the breeding data available were consistent with an autosomal recessive inheritance of the condition.
