The effect was followed up of dextrofer-100 and dextrofer-100 with B12 on the growth and fertility of minks. It was found that the i/m injection of dextrofer-100 at the rate of 0.5 cm3 per head (50 mg Fe3+), twice, at the interval of 45 days to a total of 45-day-old minks did not effect essentially their growth. The i/m application of dextrofer-100 with vitamin B12 at 0.5 cm3 per animal (50 mg Fe3+ and 40 mcg B12), singly in the beginning of the mating period to young female minks (at the age of 11 months) resulted in raising the number of offsprings from 3.4 to 4.68 (with impregnated females), and from 4.05 to 5.13 (with those that gave birth), and in lowering the number of those of the males that did not give birth as well as of those that gave birth but ate their offsprings. The weight of the obtained offsprings of the test and control males did not differ essentially between the age of 40 days and the age of 24 weeks.
