The objective was to study repeatability of mineral composition of the fur in female standard coypus in relation to their physiological condition. The concentration of Ca, K, Na, Mg, Fe, Zn, Cu, Mn, Co in the fur of female coypus were examined in selected body regions, in relation to their physiological condition (periods): 1. primiparas - sexual maturity, age of 8 months - fur maturity stage, 2. females on the day of parturition, 3. females on the day of young weaning. Concentrations of mineral elements were determined by atomic absorption spectrum photometry. Average Ca content in the dorsal region was 1754,56+/-95.49 mg/kg dry matter, in the ventral region 1756.79+/-102.80 mg/kg dry matter, K content in the dorsal region amounted to 578.60+/-50.01 mg/kg dry matter and in the ventral region to 257.99+/-26.35 mg.kg dry matter, Na content in the dorsal region made 300.88+/-19.95 mg/kg dry matter and in the ventral region 130.91+/-11.23 mg/kg dry matter, Mg content in the dorsal region was 629.48+/-41.77 and in the ventral region 656.66+/-45.22 mg/kg dry matter, Fe content in the dorsal region amounted to 150.79+/-13.95 and in the ventral region to 173.74+/-13.10, respective Zn contents were 150.97+/-2.20 and 160.41+/-3.73 mg/kg dry matter, Cu content in the dorsal region made 5.9121+/-0.2268 and in the ventral region 7.4095+/-0.3092, respective Mn contents amounted to 2.4895+/-1.732 and 5.3811+/-0.3353 mg/kg dry matter, Co contents had the values of 0.7616+/-0.0332 and 0.6758+/-0.0375 mg/kg dry matter. Repeatability of mineral element contents in the fur of standard coypus is high, for the body regions, the separate periods and in total.
