Popis: svedova M., L. v asko, a. t rebunova, R. Kasteľ, M. t uckova, M. c ertik: Influence of Linseed and Fish oil on Metabolic and Immunological Indicators of Laying Hens. acta v et. brno 2008, 77: 39-44. The metabolic and immunological indicators were determined in the blood of laying hens of ISa broWn hybrid divided into three groups, the control group and two experimental groups. the administration of n-3 polyunsaturated fatty acids (PuF a) in the form of linseed (Group 1) and fish oil (Group 2) and α-tocopherol as antioxidant to laying hens resulted in a significant increase in concentrations of high density lipoproteins (HDL) cholesterol (P < 0.05), eicosapentaenoic (ePa), docosahexaenoic (DHa) and α-linolenic acids (aa) in blood in comparison to the control group. Significantly lower levels of cholesterol (CHoL) were determined in both experimental groups at the third sampling (P < 0.05) and arachidonic acid (aa) in the fish group (P < 0.01). The metabolic activity of phagocytes and polyclonal activation of lymphocytes showed no significant differences and remained within the physiological range. oral administration of n-3 PuF a showed no significant increase of the immune response of experimental animals. Polyunsaturated fatty acids, α-tocopherol, cholesterol, immune response, poultry an increasing attention has been paid to P u Fa and their oxygenic derivatives, eicosanoids. an increased supply of n-3 P Fa decreases the level of triacylglycerols (
