The study was conducted on 20 Polish Merino ram-lambs divided into two groups: experimental (E) and control (C), each of 10 animals. From birth all the lambs were maintained with their dams and then weaned at the age of 8 weeks, placed in individual straw-bedded pens and fattened individually with a granulated concentrate mixture until reaching a mean body weight of 31.8 kg.During fattening each lamb from group E was given per os 1 ml 0.1% Na2SeO4, 3 ml 10% ZnSO4 and 60 mg vitamin E (α-tocopherol) daily. The concentrations of conjugated linoleic acid (% of the fatty acid sum) in meat (0.45%) and in liver (1.21%) were higher (P<0.05) while cholesterol kontent (42.8 mg/100g fresh matter) lower (P<0.05) in E than in C lambs. In group E total cholesterol of blood plasma decreased and HDL fraction level increased. The dietary supplementation of Se, Zn and vitamin E improved the lipid profile of lambs’ meat.

Badania przeprowadzono na 20 jagniętach merynosa polskiego, podzielonych na 2 grupy: doświadczalną (E) i kontrolną (C). Po odsadzeniu w wieku 8 tygodni, jagnięta umieszczono w klatkach indywidualnych. Jagnięta tuczono do średniej masy ciała 31,8 kg, karmiąc je do woli pełnoporcjową granulowaną mieszanką treściwą i sianem. Podczas tuczu codziennie podawano każdemu jagnięciu z grupy E per os następujące związki: 1 ml 0,1% Na2SeO4, 3 ml 10% ZnSO4 i 60 mg witaminy E (α-tocopherol). Oznaczono zawartość cholesterolu, SFA, MUFA, PUFA i CLA w polędwicy i w wątrobie jagniąt, jak również cholesterol całkowity i frakcję HDL oraz trójglicerydy we krwi. Stwierdzono, że polędwica jagniąt, którym podawano Se, Zn i witaminę E, zawierała istotnie więcej CLA (0,45%), a mniej cholesterolu (42,8 mg/100 g świeżej masy) w porównaniu z grupą kontrolną. Zawartość CLA w wątrobie jagniąt doświadczalnych również była istotnie wyższa. Stężenie cholesterolu całkowitego we krwi jagniąt doświadczalnych obniżyło się istotnie, a frakcji HDL wzrosło. Wnioskuje się, że dodanie do dawki pokarmowej dodatkowej ilości Se, Zn i witaminy E poprawia profil lipidowy mięsa jagnięcego.
