During a 2-year period from January 1, 1999, to December 31, 2000, 77 diagnoses of mulberry heart disease (MHD) were documented at the Iowa State University Veterinary Diagnostic Laboratory. Mean (+/- SD) liver vitamin E concentrations were lower (P < 0.05) in pigs with MHD (3.12 +/- 1.12 ppm, wet weight) than in pigs that died of causes other than MHD (4.80 +/- 3.2 ppm, wet weight). The majority of the pigs affected with MHD ranged in age from 3 to 7 weeks. Statistical influence of age was found on the concentration of vitamin E (P < 0.01) but not on concentration of selenium in liver in pigs with MHD. Concentrations of vitamin E below 2 ppm were considered deficient. Hepatic vitamin E concentrations below 2 ppm were measured in 25% of the pigs with gross and microscopic lesions of MHD. In contrast, liver selenium concentrations were adequate in all pigs.
在1999年1月1日至2000年12月31日的两年期间，爱荷华州立大学兽医诊断实验室记录了77例桑椹心疾病（MHD）的诊断病例。患有MHD的猪（湿重3.12±1.12 ppm）肝脏维生素E平均浓度低于（P < 0.05）死于MHD以外原因的猪（湿重4.80±3.2 ppm）。大多数受MHD影响的猪年龄在3至7周之间。发现年龄对患有MHD的猪肝脏中维生素E的浓度有统计学影响（P < 0.01），但对硒浓度没有影响。维生素E浓度低于2 ppm被认为是缺乏的。25%患有MHD大体和微观病变的猪肝脏维生素E浓度低于2 ppm。相比之下，所有猪的肝脏硒浓度都充足。
