Sažetak
Cilj ovog rada je bio ocena uticaja RYR1 genotipova na osobine trupa I frakcije lipida u krvnom serumu i musculns longissimus dorsi svinja rase poljski landras. Ispitivanja su izvedena na 32 tovljenika dve genotip grupe s: RYR1CRYR1C (n=21) i RYR1CRYR1T (n=11). Genotipovi RYR1 su identifikovani korišćenjem metode PCR/RFLP. Nivo ukupnog holesterola, HDL (lipoproteini visoke gustine) holesterol i trigliceridi su označavani prema enzimatskim metodama. Tovljenici sa RYR1CRYR1T genotipom su imali niži nivo triglicerida ukupnog holesterola, HDL- i LDL holesterola u krvnom serumu u poređenju sa životinjama iz grupe RYR1C RYR1C. Ista grupa životinjaje imala nižu količinu intramuskularne masti i holesterola u poređenju sa homozigotima RYR1CRYR1C. Intramuskulama mast heterozigota je sadržavala manje zasićenih masnih kiselina, ali vise nezasićenih masnih kiselina uključujući poli- nezasićene kiseline. RYR1 genotip nije imao značajan uticaj na ispitivane osobine tovljenika rase poljski landras.
