EMBRYO BANKS FOR THE PRESERVATION OF THE BREEDING GENE FUND OF UKRAINIAN

Abstract

In recent years, as a result of the negative impact of the factors of the socio-economic crisis in Ukraine, and especially as a result of damage caused by the destructive actions of Russian aggression, the number of livestock enterprises has decreased critically [2]. A specific feature of cattle is low fertility and a long period of growth before productive use [1, p. 43]. The combination of these significant factors prompts practical animal breeders and scientists to focus on methods of accelerated reproduction of livestock, especially highly productive breeds, and endangered Ukrainian ones, at the expense of modern methods of reproduction, in particular, embryo donation and embryo transfer. A mandatory component of these techniques is the link of cryopreservation of embryos and their accumulation in the embryo cryobank [3, p. 394, 8]. This innovative approach to embryo transfer in the conditions of dairy and meat farms of Ukraine was confirmed by the activity experience of the certified (State certificate No. 8054) Embryo Transplantation Laboratory “Poltavaplemservice”, which is shown in our previous publications and in statistical data for the period of active work of the Laboratory's biotechnologists.
