RESEARCH ON THE LONG-TERM EFFECTS OF THE CARBOHYDRATE-VITAMIN-MINERAL CONCENTRATE “LIZUNETS SOLEVIT”
The main factors constraining the development of animal husbandry is a weak fodder base, due to insufficient supply of nutrients; the costs of its production increase and becomes the cause of metabolic disorders in animals. The aim of our research was to study the embryotoxic and teratogenic effect of the new CVMC “Lizunets-Solevit” on white rats. For this reason, the drug was administered to pregnant females in the form of an aqueous suspension in different doses for 19 days. By the end of the study, no visible signs of fetal abnormalities were found after autopsy of the experimental rats. There was no significant increase in the number of corpus luteum compared with the control group at 1/10 dose by 1.1% and 1/20 dose by 1.95%, respectively. The preimplantation death of zygotes was taken into account on the embryotoxic effect of the drug, in comparison with the control group at a dose of 1/10 more by 19.7%, and at a dose of 1/20 less by 6.23%. The total embryonic mortality is higher in the experimental groups of animals by 12.69% and 3.74% than in the control. Post-implantation death of embryos in the control group was 4.99%, in the experimental 1/10 dose - 4.69% and in the experimental 1/20 dose - 6.66%. In terms of physiological development, the rat pups of the experimental groups did not differ from the control. Thus, it was found that CVMC “Lizunets-Solevit”, in doses of 1/10 and 1/20, has no embryotoxic and teratogenic effects in the body of white rats, their embryos and young animals of the neonatal and postnatal periods of life.
