Sažetak
The aim of the study was to assess the effect of organic selenium dietary supplementation on serum and tissue lipid composition after fattening period and after 48-h fasting in fattening chicken. The study was performed in the Ross hybrid line chicken divided into two groups: control group fed standard diet and Sel Plex group fed standard diet supplemented with 0.3 ppm organic selenium (Sel Plex™, Alltech). Blood, liver, intestine and adipose tissue samples were taken upon fattening completion and after 48-h fasting. Total cholesterol, HDL-cholesterol, LDL- cholesterol, triacylglycerol and lipoprotein concentrations were determined in serum, whereas total and free cholesterol, triacylglycerol, lipid peroxide and selenium concentrations and glutathione peroxidase activity (GSH-Px) were determined in tissue samples. During fattening period, the correlation of organic selenium with lipid metabolism manifested as decreased concentrations of serum triacylglycerols and VLDL (P<0.05), liver triacylglycerols (P<0.05), adipose tissue cholesterol (P<0.05) and small intestine cholesterol (P<0.05), and reduced lipid peroxidation (P<0.05). Upon chicken exposure to 48-h fasting, organic selenium supplementation resulted in increased free cholesterol concentration in adipose tissue (P<0.05), GSH-Px activity in the liver (P<0.05), and selenium (P<0.05) accumulation in the liver.
