    Okre艣lano st臋偶enie cholesterolu ca艂kowitego, HDL, LDL i trigliceryd贸w u kur rasy polbar w 8., 12. oraz 18. tygodniu 偶ycia. Materia艂 do bada艅 stanowi艂a krew pobrana z 偶y艂y od艂okciowej (v. basilica). W surowicy krwi kur oznaczono st臋偶enie cholesterolu ca艂kowitego, HDL i trigliceryd贸w metod膮 kolorymetryczn膮, wykorzystuj膮c komercyjne zestawy, natomiast oznaczanie st臋偶enia LDL wyliczono ze wzoru [Friedewald i in. 1972]. St臋偶enie cholesterolu ca艂kowitego i HDL w surowicy krwi kur rasy polbar by艂o zale偶ne zar贸wno od p艂ci ptak贸w, jak i ich wieku. Nieznacznie wy偶sze warto艣ci badanych wska藕nik贸w wyst臋powa艂y u kogut贸w. St臋偶enie LDL u kur rasy polbar mala艂o, natomiast st臋偶enie trigliceryd贸w wzrasta艂o wraz z wiekiem ptak贸w. Wy偶sze warto艣ci cechowa艂y p艂e膰 m臋sk膮. Uzyskane wyniki st臋偶enia cholesterolu ca艂kowitego, HDL, LDL i trigliceryd贸w, u skonsolidowanej genetycznie rasy kur p贸lbar, mog膮 by膰 wykorzystywane do por贸wna艅 z innymi rasami drobiu.Total cholesterol content as well as HDL, LDL and trigliceride levels were determined in 8-, 12- and 18-week old polbar cocks and hens. The material for analysis was blood collectedfrom the basilic vein (v. basilica). In the blood serum determination of the total cholesterol content as well as HDL and triglyceride levels, whereas the LDL concentration level was calculated from an appropriate formula. The total cholesterol content and HDL levels in the polbar hen serum were both sex and age-dependent. Slightly higher values were determined for the cocks. LDL concentration in polbar hens decreased along with age, whereas triglyceride levels increased as the birds grew older. Themales were characterized by higher concentration levels. The obtained concentration values for total cholesterol, HDL, LDL and triglycerides in the genetically consolidated polbar chickens can be employed for comparisons with other poultry breeds
