Abstract

Namen magistrskega dela je bil preučiti prebavljivost železa pri laboratorijskih miših, ki so bile izpostavljene pomanjkanju železa. V okviru študije smo preučevali vpliv dveh različnih krmnih mešanic ene z dodatkom železa in druge brez dodatka ter uporabo dveh različnih oblik dodatka železa, anorgansko vezano železo (železov sulfat) in mikronizirano mikroenkapsulirano elementarno železo (železov sirup), preko gavaže na prebavljivost železa. Glavni cilj je bil oceniti, kako učinkovito miši absorbirajo železo iz teh različnih virov in izračunati navidezno prebavljivost z uporabo klasične in indikatorske metode. Naši rezultati so pokazali, da dodatek železa v obliki železovega sulfata ali železovega sirupa, preko gavaže pomembno vpliva na prebavljivost železa. Najvišjo navidezno prebavljivost železa je imela skupina v pogojih anemije, ki je prejemala raztopino železovega sulfata preko gavaže. S tem smo ovrgli hipotezo, da bo pri dodatku železovega sirupa prebavljivost boljša v primerjavi z dodatkom železovega sulfata. Smo pa hkrati potrdili hipotezo, da imajo miši v pogojih pomanjkanja železa boljšo prebavljivost železa v primerjavi z mišmi, ki so dobivale krmo z dodanim železom.

Secondary title: Iron digestibility in laboratory mice under conditions of iron deficiency
Secondary abstract: The aim of the M. Sc. thesis was to investigate iron digestibility in laboratory mice with iron deficiency. The study investigated the effect of two different diets, one with (control group) and the other without (anaemic group) iron supplementation, as well as the use of two different forms of iron supplementation, anon-organic bound iron (ferrous sulphate) and micronized microencapsulated elemental iron (ferrous syrup), via gavage, on iron digestibility. The main objective was to evaluate the iron intake of mice from these different sources and to calculate the digestibility using classical and indicator methods. Our results show that iron supplementation in the form of ferrous sulphate or iron syrup via gavage has a significant effect on iron digestibility. The highest apparent iron digestibility was observed in the anaemic group receiving the ferrous sulphate solution by gavage. This disproved the hypothesis that digestibility is better with iron syrup supplementation than with ferrous sulphate supplementation. However, we also confirmed the hypothesis that mice under iron-deficient conditions have better iron digestibility than mice fed an iron-containing diet.
