Abstract This study aimed to investigate the effects of dietary supplementation with modified-hen-egg-yolk on plasma lipids and lipoprotein profiles in rats. During the four-week-experiment, 64 Wistar rats were divided into four groups of 16 (eight of both sexes), and fed commercial rat food (group C); food containing 70% commercial rat mixture and 30% freshly cooked egg yolk originating from laying hen eggs fed with 3% fish oil (group F); 3% palm olein (group P), or 3% lard (group L). The cooked egg yolk in the rat diet affected the concentrations of plasma total and LDL-cholesterol in males of the P and L groups. Cholesterol and total fat in the diet did not have a hypercholesterolemic effect on their own, but when in combination with fatty acid composition, they could contribute to an increase in plasma total and LDL cholesterol concentrations in rats. HDL-cholesterol was the most resilient plasma lipoprotein of rats to dietary treatments in our experiment. Compared to the control group, the addition of hen egg yolk to the rat diet regardless of its quality, adversely affected the values of HDL-C/TC and HDL-C/LDL-C in both males and females.
Pramenka je ovca kombiniranih svojstava, skromna u ishrani, vrlo otporna i dobro prilago ena našim uvjetima, ali slabih produktivnih osobina jer se uzgaja u brdsko-planinskim uvjetima, nepovoljnim za intenzivniju proizvodnju sto ne hrane, zbog ega je ishrana veoma esto kvantitativno i kvalitativno nedostatna. Na pravilnost ishrane ukazuje razina njihove proizvodnje, ali i njihov metaboli ki status koji se prosu uje odre ivanjem biokemijskih parametara krvi. Biokemijski parametri krvi mogu ukazati na energetsku, proteinsku i mineralnu opskrbu organizma, a istovremeno i na zdravstveni status životinje. Stoga smo proveli ispitivanje širokog spektra biokemijskih parametara u krvi ovaca s dva lokaliteta, op ine Livno i Travnik, u ljetnom razdoblju kada su životinje bile na ispaši karakteristi nog botani kog sastava navedenih podru ja, a sve s ciljem usporedbe sa standardnim vrijednostima parametara za ovce, ali i me usobnih podataka s dva razli ita podru ja. Krv je uzorkovana iz v. jugularis i u serumu su odre ivani sljede i biokemijski parametri: glukoza, Mg, P, Ca, ukupni proteini, LDH, GGT, AST, ALT, ALKP, kolesterol, trigliceridi, urea i albumini. Važnost istraživanja je u injenici da se prou avanjem metabili kog statusa unapre uju saznanja o interakciji lokalnog uzgoja i metabolizma ovce u funkciji održivosti autohtonih pasmina.
