Selenium (Se) deficiency induces myocardial necrosis in chickens, but the exact mechanism remains unclear.The objective of this study was to investigate the effect of dietary Se deficiency on 26 mineral elements in myocardium of chicken.One hundred and eighty 1-day-old chickens were randomly divided into two groups.The control-Se group (C group) was fed a medium-Se diet containing 0.2 mg Se/kg and the low-Se group (L group) was fed a Se-deficient basal diet containing 0.033 mg Se/kg.At the end of the 55 days period, myocardium was collected and the contents of 26 mineral elements lithium (Li), boron (B), natrum (Na), magnesium (Mg),aluminium (AI), silicium (Si), kalium (K), calcium (Ca), vanadium (Ⅴ), chromium (Cr), manganese (Mn),ferrum (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), molybdenum (Mo),cadmium (Cd), stannum (Sn), stibium (Sb), barium (Ba), hydrargyrum (Hg), thallium (Tl) and plumbum (Pb) were assayed by inductively coupled plasma mass spectrometry (ICP-MS).The results indicate that 10 element levels were significantly changed (P<0.05) in L group compared to C group.Hereinto, 7 element levels were (Li,Cu, Zn, Sb, Ba, Hg and Pb) significantly increased (P<0.05) in L group compared to C group, 3 element levels (Mn, Fe and Se) decreased significantly (P<0.05).These data suggest that Se deficiency leads to a disorder of 10 mineral (Li, Mn, Fe, Cu, Zn, Se, Sb, Ba, Hg and Pb) in myocardium of chicken.
