摘要：
A four-week experiment was carried out on piglets to observe the effects of Fe, Cu, Zn, Mn, and Se bioplexes on the micromineral profile of blood serum, excretion of these trace elements in faeces and urine, and body weight. Organic trace element supplementation resulted in a significant increase in blood serum concentrations of Fe (P < 0.01), Cu (P < 0.05 - 0.001), Zn (P < 0.05 - 0.01), Mn (P < 0.01); the concentration of Fe in liver (P < 0.05); Se in the heart (P < 0.05), kidneys (P < 0.01), bones (P < 0.05); and Mn and Zn in bones (P < 0.01). Conversely a positive decrease in the levels of excreted trace elements in faeces and the urine of pigs in the prefattening period was observed. The optimisation of homeostasis was manifested by the higher weight gain during the experiment.
