title: Dietary effect of dried bay leaves (Laurus nobilis) meal on some biochemical parameters and on plasma oxidative status in New Zealand white growing rabbit.
abstract: Effects of dietary supplementation of Laurus nobilis on selected biochemical parameters and plasma oxidative status in growing rabbits, fed with and without enriched-fat diet, integrated with and without dried bay leaves meal, were investigated. In the test, 120 New Zealand white 35-day-old male rabbits were divided into four homogeneous groups of 30 animals each. A negative control group (CON) received a feed that met the animal nutrient requirement; a positive control group (CG) receiving a supplement of 2.5% pig fat in feed; an experimental group (GA) feeding an integration of 2.5% pig fat and 1 g/kg of dried bay leaves (Laurus nobilis) in feed; an experimental group (CA) with dried bay leaves at the rate of 1 g/kg in feed. The dietary integration with dried bay leaves meal have resulted in a significant decrease in the blood lipid profile, glycemic profile and liver enzymes, with reduced levels of ALT and AST, glucose, total cholesterol, LDL cholesterol, triglycerides and increased HDL cholesterol. Plasma oxidative status markers have statistically improved with an increase in blood total phenols, SOD, ORAC, the FRAP and lipo-vitamin concentration, together with a significant reduction in ROMs and the MDA values. The results of present research underline that the dietary treatment with bay leaves meal, in the extend of 1 g/kg feed, confirms the lowering cholesterol activity and the epato-protective and ipo-glycemic effect in enrich-fat diet, controlling the oxidative status of plasma markers.
