Females of the experimental groups were characterized by slightly higher sexual activity during the chase and a lower percentage of females who did not give birth. A 27% increase in fertility was observed in female minks of group D1, which were additionally injected with succinic acid at the rate of 10 mg / kg live weight before the mating season. Also, the positive effect of succinic acid as a biologically active supplement is evidenced by the greater number of offspring obtained on a female puppy of the second experimental group D2, which was additionally introduced into the diet of biologically active additive (succinic acid) at a dose of 50 mg / kg body weight compared to similar to the female control group, the advantage was 15%. Biologically active supplements, which include succinic acid, affect the work of all cells in the body, stimulating their activity. Further research will be able to expand the understanding of the mechanism of action of this drug. The introduction of succinic acid in general had a positive effect on the dynamics of live weight gain of young animals after weaning. At 60 days of age, puppies of both experimental groups with a significant difference in the weight of the young of the control group, with the most effective was the introduction of the drug at a dose of 50 mg / kg. Young mink grew more intensively and significantly outperformed peers in the control group by 19.98 g (P> 0.99). At the age of 90 to 150 days, the effectiveness of the drug at a dose of 10 mg / kg in terms of live weight prevailed over peers of the control group.
