Sažetak
The purpose of this study was to investigate the effect of fasting on lipid concentrations and lipoprotein lipase activity in breast and thigh muscle of Ross 308 broiler chickens. Muscle tissue samples were collected at the age of 42 days and after 48 hours food deprivation and triacylglycerol, cholesterol and lipid peroxide concentrations and lipoprotein lipase activity were assayed. After fattening period, triacylglycerol concentrations (p<0,05) and lipoprotein lipase activity (p<0,05) in chicken thigh muscle were higher compared with breast muscle. Fasting significantlydecreasedtriacylglycerols(p<0,05)and cholesterols (p<0,05) and increased lipid peroxidation (p<0,05) in thigh muscle of chickens. At the same time, lipid peroxidation intensity significantly decreased (p<0,05) inbreast muscle. Lipoprotein lipase activity in breast muscle significantly increased (p<0,05 )whereas in thigh muscle decreased (p<0,05) after fasting. The results of this study confirm the differences in lipid metabolism of breast and thigh muscle of chickens. Thigh muscle has higher triacylglycerol concentrations and lipoprotein lipase activity after fattening period but after fasting lipid content of the thigh muscle decrease whereas susceptibility of muscle to lipids peroxidation increase.
