The effect of enzyme supplements and high amounts of white lupins on concentrations of lipids in serum and meat in fattening chickens

Abstract

A bi-factorial experiment was conducted to investigate the effect of enzyme supplements (200 mg Roxazyme G per kg feed) and white lupins (35%, freshly harvested or stored) on concentrations of lipids in serum and lipoproteins as well as in chest and leg meat. Enzyme supplements had not any effect on concentrations of cholesterol, triglycerides and phospholipids in serum and lipoproteins and on concentrations of triglycerides and cholesterol in meat. In contrast, feeding the rations with 35% lupins lowered concentrations of triglycerides and phospholipids in serum as well as concentrations of total cholesterol, triglycerides and phospholipids in high-density lipoproteins. However, freshly harvested and stored lupins partially had different effects on those parameters. Lipids in low-density lipoproteins were not affected by lupins. Feeding the rations with 35% lupins increased triglyceride concentrations in thigh muscle whereas triglyceride concentration in chest muscle as well as cholesterol concentration in both pieces were not changed. Clinical-chemical parameters related to protein metabolism were not affected by either enzyme supplements or lupins.
