title: Hepatosis dietetica, nutritional myopathy, mulberry heart disease and associated hepatic selenium level in pigs.
abstract: Outbreaks of Hepatosis Dietetica (HD), Nutritional Myopathy (NM) and Mulberry Heart Disease (MHD) in Western Australia are described. Hepatic selenium concentrations were low in pigs with HD and NM, but not with MHD. The mean hepatic selenium concentration in pigs unaffected with these conditions was 1.07 +/- 0.12 ppm dry wt. Cereal grain in an area of Western Australia where HD and NM frequently occur was found to be low in selenium and the addition of 0.1 ppm selenium to pig rations appeared to be an effective prophylactic measure. The extensive use of lupin seed as a protein source replacing much of the meat meal in pig rations may have contributed to an increase in the incidence of HD and NM.
