Abstract
Between June and October 1975 enterotoxaemia was diagnosed in 17 litters of young sows and in 22 litters of old sows (19.5% of all litters). Of 2038 live piglets born, 180 died in the first 24 hours and 125 at two to ten days of life. Among these, PM examination revealed enterotoxaemia in 93 (4.5%). Losses within the four farrowing groups varied between 2.3% and 12.3%. Clinical symptoms in the peracute, acute, subacute and chronic forms of the disease are described and illustrated. The origin is unknown but experience showed that the disease can persist for a long time in a farm. Consumption of sawdust in varying amounts by piglets may have been a contributory factor. Vaccination in October 1975 reduced total losses from 14% to 12%. After revaccination of old sows before the next farrowing no further losses from this cause were clinically diagnosed.
