The study was conducted on 40 Polish Merino ewes divided into two groups: experimental (E) and control (C), each of 20 animals. Four weeks before, and then on day 1, week 3 and week 6 post lambing all ewes from group E were given intramuscularly 5 ml 0.1% Na2SeO4, 10 ml 10% ZnSO4 and 250 mg vitamin E. In milk sampled 7 weeks after lambing the concentration of conjugated linoleic acid (0.66% of the fatty acid sum) was found higher (P<0.05) while cholesterol content (10.6 mg/100ml) lower (P<0.01) in group E than in group C. In group E, over the whole experiment, the level of total cholesterol of blood plasma dropped from 3.79 mmol/L to 3.02 mmol/L while HDL fraction increased from 0.85 mmol/L to 0.98 mmol/L. It is concluded that the pre- and post-partum intramuscular injections of Se, Zn and vitamin E improved the lipid profile of milk.

Badania przeprowadzono na 40 owcach merynosa polskiego, podzielonych na dwie grupy –doświadczalną (E) i kontrolną (C), po 20 zwierząt w grupie. Owcom z grupy E cztery tygodnie przed wykotem, a dalej po jednym dniu, po 3 tygodniach i po 6 tygodniach od wykotu podawano w iniekcji domięśniowej 5 ml 0,1% Na2SeO4, 10 ml 10% ZnSO4 i 250 mg witaminy E (α-tokoferol). Oznaczono zawartość cholesterolu, SFA, MUFA, PUFA i izomerów CLA w mleku owiec, jak również cholesterolu całkowitego i frakcji HDL oraz trójglicerydów w osoczu krwi. W mleku owiec z grupy E stwierdzono istotnie więcej izomerów CLA (0,66%), a mniej cholesterolu (10,6 mg/100 ml) niż w mleku grupy kontrolnej.W badanym okresie stężenie cholesterolu całkowitego we krwi owiec z grupy E (3,02 mmol/l) obniżyło się istotnie, a frakcji HDL (0,98 mmol/l) istotnie wzrosło. Wnioskuje się, że czterokrotne domięśniowe podanie Se, Zn i witaminy E (za każdym razem odpowiednio po 2,09, 227 i 250 mg) poprawia profil lipidowy mleka owczego.
