Effect of organic selenium food suplementation and fasting on adipose tissue lipid concentrations and lipoprotein lipase activity in broiler chickens
The aim of this study was to investigate the effect of the organic selenium supplementation and fasting on lipid concentrations and lipoprotein lipase activity in adipose tissue of Ross 308 broiler chickens. Chickens were divided into two groups: first group were fed with standard diet (control group) and second were fed the same diet supplemented with organic selenium (Sel-Plex group). Adipose tissue samples were collected at the age of 42 days and after 48-hours food deprivation and triacylglycerol, total and free cholesterol concentrations and lipoprotein lipase activity were assayed. Adipose tissue total cholesterol concentration in the chickens fed with organic selenium supplementation was significantly lower (P<0.05) compared with control after fattening period. Fasting significantly decreased total and free cholesterol (P<0.05) concentrations in control chickens and increased free cholesterol concentration (P<0.05) in organic selenium supplemented chickens. Lipoprotein lipase activity in chicken adipose tissue of both control and Sel-Plex groups were significantly increased (P<0.05) after fasting. In both groups, no changes in triacylglycerol concentrations were observed after fattening period and 48-hour food deprivation (P>0.05). Present research suggests that organic selenium supplementation influences cholesterol metabolism in adipose tissue by decreasing total cholesterol concentration during the fattening period and increasing free cholesterol concentration after 48-hour food deprivation.
