Abstract

Mulberry heart disease (MHD) in pigs is characterized by lesions of acute haemorrhagic myocarditis and myocardial necrosis. The objectives of this study were to determine the levels of vitamin E and selenium and 13 other trace minerals in heart and liver tissues and to determine the prevalence of certain viral infections in heart tissues from MHD-affected and MHD-unaffected pigs and the vitamin E and selenium concentration in feed samples from selected farms with MHD. Based on the pathological examination, 114 pigs were separated into MHD lesion-negative (L-NEG) (n=57) and MHD lesion-positive (L-POS) (n=57) groups. Seventy-three samples (40L-NEG and 33L-POS) were subjected to chemical analysis, and 66 (32L-NEG and 34L-POS) were subjected to PCR detection for viral pathogens. Lower (P
