ABSTRACT

An animal model study was undertaken in order to determine the effect of modifying
diet composition and its supplementation with calcium, magnesium, zinc and chromium
on protein metabolism. The study was conducted on 36 female rats aged 5–6
months, kept in individual cages Group I received basal feed mixture, Groups
II and III – modified feed mixture. For drinking the animals from Groups
I and II received tap water, Group III – an aqueous solution of mineral
components (270 mg Ca2+; 60 mg Mg2+; 3.96 mg Zn2+ and
0.726 mg Cr3+ per 1 kg of
feed mixture).


Diet, in which whole grains of cereals were substituted for wheat flour and
saccharose and supplemented with Ca, Mg, Zn and Cr, caused a reduced intake of
feed and proteins, which could be the reason of lower protein content in muscles
of the animals. Modification of diet composition affected the increase in the
concentration of α1-globulins in blood, which might indicate an ongoing
inflammatory process, whilst the supplementation with mineral components made
no difference in this respect. The supplementation with Ca, Mg, Zn, Cr did not
restore the values of selected markers of protein metabolism determined in plasma
of the animals fed the modified feed mixtures to the levels noted in the animals
receiving basal diet.

Key words: Female rats, mineral supplementation, protein metabolism.
