Skin-hair cover mineral metabolism of standard mink for the different post-natal ontogenesis phases

Concentrations of macro- and microelements: K, Ca, Mg, Na, P, Co, Cu, Cr, Fe, I, Mn, Se, Zn have been determined by atomic-emission and mass-spectrometry in Optima-2000 DM and ELAN-9000 (Perkin-Elmer, USA) in standard mink blood, skin and hair and feed. Biological absorption coefficient (BAC) of mineral elements by standard mink blood, skin and hair from feed change with age of mink and have definite value for different post-natal ontogenesis phases.
