A 550-sow farrow-to-finish herd reported an increased incidence of sudden death in sows. Results of gross necropsy indicated severe ascites, hepatomegaly, cardiomegaly, and pulmonary edema, suggesting heart failure. This diagnosis was supported by a finding of hyperkalemia in nine of 14 sows blood sampled. Cottonseeds observed in the feed contained gossypol, a compound known to be cardiotoxic, at concentrations of 62 to 83 mg per kg. The diet was replaced and evidence of toxicosis abated over the subsequent 3 months.
