SCIENTIFIC ACTIVITY OF TROTSKYI PETRO ANATOLIYOVYCH – THE MASTER OF AGRICULTURE (to the 55th anniversary of the birth)

Abstract

The purpose of the article is to highlight the scientific achievements of P. A. Trotskyi, the Master of Agriculture, the biotechnologist in the field of animal husbandry, and his contribution to the development of research in biotechnology, the preservation of the gene pool of agricultural animals. Research methods are general scientific (analysis, bibliographic), retrospective and source studies.
 The scientific novelty of the article lies in the presentation of the results of P. A. Trotskyi's scientific works, which contribute to solving the problem of preserving animal husbandry resources and improving methods of long-term preservation of genetic material. Among them: the development of new biotechnological methods of cryopreservation of gametes of farm animals to implement the objectives of the methodology of the Bank of Animal Genetic Resources at the cellular level using embryological genetics methods; the use of deconserved oocytes for the rational use of the genetic potential of highly productive and breeding females and obtaining more offspring from them.
 The researcher was directly involved in the development of methodological aspects of the preservation of the gene pool of farm animals, which include a description of the main stages of obtaining embryos of farm animals in vivo and in vitro, their quality assessment and cryopreservation procedures. One of the main ways of implementing industry-wide programs to preserve and maintain the diversity and specificity of gene pool objects is the functioning of the Bank of Animal Genetic Resources. Together with his colleagues, the scientist defined its role in programs of cryopreservation of genetic resources, described the main requirements for the physical structure of the bank, its tasks and functions in the system of preservation, reproduction and selection of agricultural animals.
 The results of P. A. Trotskyi's scientific developments were taken into account in the preparation of "Methods of scientific research on breeding, genetics and biotechnology in animal husbandry" (2005) and "Program for the preservation of the gene pool of the main species of agricultural animals in Ukraine for the period until 2015" (2009). With the participation of the scientist, a cryocollection of 44 eggs of the Myrhorod breed was created in the Bank of Animal Genetic Resources, which is necessary for the accelerated recovery and preservation of local pig breeds of Ukraine. Based on the functioning of the Bank, the methodology of cryopreservation of genetic resources of agricultural animals will be implemented, including as "virtual gene pool cryoherds".
