Prospects of developing Ukraine's agriculture are studied taking into consideration the concept of development of stable systems, wherein a rate of ecological changes and an increase of a man-caused load are taken into account. An animal constituent is noticed to be an active factor affecting the agrosystems. The analysis of genetic structure is carried out according to seven polymorphic genetic and biochemical systems of four breeds and 21 intrabreed group of cattle, which is recreated in different ecologo-geographic conditions. Based on the results obtained, one can assume that the autochtonous breeds are more genetically consolidated than commercial ones and they require less transformations of the population-genetical structure while carrying out the adaptation to the new rearing conditions
