Six female coypus of different mutations - standard, Greenland, silver and white were housed in halls, in one-storey cages with pools. They received granular feed mixture KK, and alfalfa and fodder beet as saturation supplement. Water from pools was used for drinking. The objective of the trial was to determine Ca, K, Na, Mg, Fe, Zn, Cu, Mn, Co concentrations in the fur of female coypus in certain body regions, in the central dorsal and ventral regions, and in relation to the physiological condition (stage): 1. primiparas, age of 8 months-fur maturity stage, 2. females on the day of delivery, 3. females on the day of young weaning. Element contents were determined by the method of atom absorption spectral photometry. The results were subjected to mathematico-statistical processing by two-factor analysis of variance. Mineral composition of the fur of adult female coypus varies in relation to age, genotype and physiological condition.
