Sadi Cetingul %A Abdullah Eryavuz %A Recep Aslan %A Yylmaz Dundar %A Fatma Inal %J Journal of Animal and Veterinary Advances %D 2012 %I Medwell Online %X This research has been performed to determine the effects of Hazelnut Oil (HO) and Sunflower Oil (SO) added in the layer ration at various levels as an energy source onto lipid peroxidation and blood parameters of laying hens. Eight hundred laying hens at 135 days of age were used as research material in this experiment. The hens were divided into 5 groups and then each group was divided into 10 subgroups containing 16 hens each. No oil was added in feeds of control group. The other groups were given 15 g kg 1 HO; 15 g kg 1 SO; 30 g kg 1 HO and the last one was mixed oil given 30 g kg 1 MO (15 g kg 1 HO + 15 g kg 1 SO). No difference has been observed in terms of Malondialdehyde (MDA), Glutation (GSH), Total Cholesterol (TCH), mean corpuscular volume (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), Mean Cell Volume (MCV), glucose, White Blood Cells (WBC), Red Blood Cells (RBC), Hemoglobin (HB), Packed Cell Volume (PCV) and Thrombocyte (TB) values among the groups. The source and level of the oil used in this study did not affect lipid peroxidation and hematological values. %U http://www.medwellonline.net/abstract/?doi=javaa.2008.1631.1634
