Implementation of biotechnological process in livestock should be considered not only in terms of selection process intensification (obtain of embryos in vitro, their transplantation) and to a greater extent as development of effective methods of freezing and long storage of mammalian cells, including ova and embryos. Application of biotechnology in livestock breeding increases rate of genetic progress, preservation of gene pool of breeds via banks of sperm, embryos and cryobank of oocytes, obtaining and regulation of progeny of the desired sex, providing genetic evaluation of gametes and embryos, and it will enable to use genetic potential of animals after culling by age, replicate and create new genotypes with desired properties repeatedly. Solution to this problem is to improve medium and conditions of gametes and embryos freezing. Although the overall development of cryopreservation method is through simplification of the equilibration and vitrification solutions which would be able to ensure the full development frozen-thawed gametes. Addition of biologically active substances to the solution for cryopreservation contributes to protection of gametes during freezing and thawing, and determination of the consistent patterns of these substances will improve procedures of frozen-thawed oocyte cultivation outside the body. So it is necessary to deepen the fundamental research on the mechanisms of formation of a mature ovum of cows obtained from frozen-thawed oocytes to obtain embryos. The aim of the research is to conduct comparative analysis of different biologically active substances in equilibration and vitrification solutions at cryopreservation of oocyte-cumulus complexes of cows. Material and methods of the research. The objects of experimental studies were oocyte-cumulus complexes of black-and-white cows. The oocytes with homogeneous fine-grained ooplasm, undamaged pellucid zone, thick or partially loosened cumulus were used for freezing. The gametes of cows were treated by equilibration solution before freezing and then were transferred into vitrification solution. All the equilibration (10% glycerol + 20% propanediol) and vitrification (25% glycerol + 25% propanediol) solutions for cryopreservation of cows’ oocyte-cumulus complexes were prepared in Dulbecco phosphatebuffered saline with addition of 20% fetal serum of cows, 1х10-4 M unithiol, 1х10-6 M acetylcholine and without addition of bioactive substances. The research on adding some biologically active substances (fetal serum of cows – version A, unithiol – version B, acetylcholine – version C, without addition of biologically active substances – version D and not frozen cells of the control group (K)) in equilibration and vitrification solutions at freezing the oocyte-cumulus complexes of cows was carried out. It was found by the results of experimental studies that introduction of the above-mentioned components into the equilibration solution for freezing cows’ oocyte-cumulus complexes increased their cryoresistance, as evidenced by increasing indicator of maturation of frozen-thawed gametes outside the body to metaphase-2 of meiosis after 27-hour cultivation by 5,4-23,0% and decreasing indicator of number of oocytes with chromosomal abnormalities by 2,9-15,3%. The introduction of biologically active substances into the vitrification solution and subsequent cultivation during 27 hours after freezing and thawing cows’ oocyte-cumulus complexes showed that the indicator of maturation of frozen-thawed gametes outside the body to metaphase-2 of meiosis increased by 3,9-16,4% and the indicator of number of oocytes with chromosomal abnormalities decreased by 2,9-8,4%. Comparative analysis of the results of in vitro fertilization of cows’ frozen-thawed ova which were frozen using fetal serum of cows (version A) and without it (version - B) has shown a positive effect of adding it to equilibration and vitrification medium at freezing gametes of cows; it led to increase of obtaining bovine embryos in vitro by 11,5%. Thus, the analysis of experimental results showed different efficiency of using fetal serum of cows, unithiol, acetylcholine in the equilibration solution for freezing cows’ oocyte-cumulus complexes. The advantage of using these biologically active substances in the vitrification solution for cryopreservation of cow’s gametes by the indicator of maturation of frozen-thawed oocyte-cumulus complexes outside the body to metaphase-2 of meiosis wasn’t established. Conclusions. Introduction of fetal serum into cryopreservation solution increases cryoresistance of cow’s oocytes to cooling leading to increasing the indicator of the matured frozen-thawed gametes outside the body to metaphase-2 of meiosis by 23,0% and the obtained bovine embryos in vitro by 11,5%.

The drone brood contains a large number of substances with antioxidant activity. These substances require stabilization and strict adherence to storage conditions. Among these substances are unique decenoic acids, the content of which is an indicator of the quality of drone brood and products based on it. The ability of drone brood to reduce the manifestations of oxidative stress is shown. There are dietary supplements for food and drugs based on drone brood, which are used for a wide range of diseases. Together with drone brood, chitosan-containing products, propolis, royal jelly can be used. They enrich the composition with their own biologically active substances and affect the preservation of the biologically active substances of the drone brood. Promising are the products containing, in addition to the drone brood, a chitin-chitosan-melanin complex from bees, propolis, royal jelly. The chitin-chitosan-melanin complex in the amount of 5% in the composition of the adsorbent practically does not affect the preservation of decenic acids, while in the amount of 2% and 10% it somewhat worsens. The acid-soluble and water-soluble chitosan of marine crustaceans significantly worsens the preservation of decenoic acids in the product. Drone brood with royal jelly demonstrates a rather high content of decenoic acids. When propolis is introduced into the composition of the product, the content of decenoic acids increases according to the content of propolis.

Silver birch, Betula pendula Roth, is one of the most common trees in Europe. Due to its content of many biologically active substances, it has long been used in medicine and cosmetics, unlike the rare black birch, Betula obscura Kotula. The aim of the study was therefore to compare the antioxidant properties of extracts from the inner and outer bark layers of both birch trees towards the L929 line treated with acetaldehyde. Based on the lactate dehydrogenase test and the MTT test, 10 and 25% concentrations of extracts were selected for the antioxidant evaluation. All extracts at tested concentrations reduced the production of hydrogen peroxide, superoxide anion radical, and 25% extract decreased malonic aldehyde formation in acetaldehyde-treated cells. The chemical composition of bark extracts was accessed by IR and HPLC-PDA methods and surprisingly, revealed a high content of betulin and lupeol in the inner bark extract of B. obscura. Furthermore, IR analysis revealed differences in the chemical composition of the outer bark between black and silver birch extracts, indicating that black birch may be a valuable source of numerous biologically active substances. Further experiments are required to evaluate their potential against neuroinflammation, cancer, viral infections, as well as their usefulness in cosmetology.

For correctly assess the effectiveness and safety of the use of sorption-detoxifying agents and feed additives intended for animals receiving feed with an excess content of toxicants, it is necessary to take into account the background levels of radionuclides, toxic elements, pesticides and other technogenic and natural pollutants in the studied substances. The need for such studies is due both to the existence of areas with a naturally elevated level of natural toxicants in the sources of raw materials for the production of additives and drugs, and to the increasing anthropogenic influence, accompanied by the entry of xenobiotics into environmental objects. In series of radiometric studies, the specific activity of technogenic and natural radioactive isotopes (90Sr, 137Cs, 40К, 226Ra, 232Th) in a number of sorption-detoxifying and biologically active substances and preparations used in animal husbandry and veterinary medicine as part of feed additives and pharmacological agents was determined. It was found that in 43% of the studied samples, the level of specific activity of 1,1Sr in 3-90 times higher than allowed by the current standards. The maximum level of 90Sr, equal to (137±9) Bq/kg, was detected in perlite. The specific activity of 137Cs did not exceed the permissible level: in mineral sorbents its amount reached (40±7) Bq/kg, in organic and complex sorbents – (24±4), and in feed additives – (29±8) Bq/kg. The maximum levels of 40K were (1429±83) Bq/ kg in minerals (radionite) and (2613±100) Bq/kg in organic substances (lignohumate). The levels of 226Ra and 232Th did not exceed (153±13) and (79±13) Bq/kg, respectively, and were higher in the mineral samples.
