INTESTINAL RUPTURE IN SOWS FED WHEY

Abstract
A problem of sudden deaths was investigated on a 600 sow piggery after 35 (8%) mature sows died during 10 mo. Thirty four (90%) of the sows which died in the following 20 mo. were all fed whey and had acute severe peritonitis associated with rupture of the large or lower small intestine. No similar deaths occurred in sows, gilts or boars receiving only formulated feed pellets. Ruptures apparently resulted from overdistention with gas produced from whey and that the likelihood of their occurrence was directly related to the volume of whey ingested.
