After the addition of selenium to swine feed (max. 0.1 ppm) was legalized in Denmark in 1975, a marked reduction has occurred in the incidence of hepatosis dietetica (HD) in the material received at the State Veterinary Serum Laboratory for diagnostic examination, while the incidence of mulberry heart disease (MHD) appears to be unchanged (Table I). In a material collected before the addition of selenium to swine feed was permitted, the selenium content in liver and heart was found to be significantly lower in the pigs that had died of MHD than in normal pigs, but higher than in pigs that had died of HD (Table II). These observations tend to support the view that feed supplementation with selenium is more effective to prevent HD than MHD.
1975年丹麦将在猪饲料中添加硒（最大0.1 ppm）合法化后，国家兽医血清实验室接收用于诊断检查的材料中，营养性肝病（HD）的发病率显著降低，而桑椹心病（MHD）的发病率似乎未变（表I）。在猪饲料中允许添加硒之前收集的一份材料中，发现死于MHD的猪肝脏和心脏中的硒含量显著低于正常猪，但高于死于HD的猪（表II）。这些观察结果倾向于支持以下观点，即饲料中添加硒预防HD比预防MHD更有效。
