Dynamics of macroelements content in blood of foxes (Vulpes vulpes) with different genotypes in postnatal ontogenesis

Abstract

Abstract The dynamics of macronutrients in blood of foxes (Vulpes vulpes L., 1758) of two coloring genotypes: silver-black (A/a b/b; a/a B/B) and Vyatka moth (A/A B/B) in postnatal ontogenesis - at the age of 2, 4, 6 and 12 (adults) months. Macronutrients were determined by the capacity of a semi-automatic biochemical analyzer “BioChem SA” (the USA) using reagent kits from High Technology (the USA). In growing young foxes of coloring genotypes: silver-black (A/a b/b; a/a B/B) and Vyatka moth (A/A B/B), the final profile of the content in the blood of macronutrients Ca2+, Mg2+ and phosphorus is formed by the age of 6 month. Moreover, only in Vyatka moth males (A/A B/B) at the age of 2 months a significant effect of the genotype on the increase in Ca2+ level was noted, in females of the same genotype at the age of 4 months – on the increase in the level of Mg2+. The obtained data can be used as reference values in the study of the etiology and pathogenesis of diseases accompanied by impaired metabolism of macroelements.
