The purpose. To generalize results of reaching of scientists of IAHSZ "Askania-Nova" in branch of animal husbandry and to light problems and prospects of scientific researches in modern economic and nature-climatic conditions in Ukraine. Methods. Selection-genetic, immune-genetic, genetic-biochemical, population-genetic, technological, biometric. Results. Results are given of work of scientists of the Institute in selection, genetics and technology of animal husbandry of South region of Ukraine, as well as problem and perspectives of branch in modern economic and nature-climatic conditions. Series of highly productive gene pools of animals in sheep breeding, cattle husbandry and swine breeding which make the basis of genetic resources in region, and for sheep breeding -in the state as a whole, had been created during existence of the institute. Modern selection-genetic methods and methodology of development of existing and creation of new breeds, types and lines of animals, technologies of production and processing of products of sheep breeding, modern biogeotechnology of duplicating valuable genotypes are developed. Use of scientific developments provides high level of productivity of branch and short terms of their pay-back. Conclusions. Scientists of IAHSZ "Askania-Nova" (centre of science selection in the south of Ukraine) developed a series of selection-genetic, technological, biotechnological methods, techniques, system of assessment and development of genotypes of animals. That allowed creating of domestic highly productive, adapted to extreme natural-climatic conditions of the region gene pools of cattle (milk and meat directions of productivity), sheep and pigs. Today these animals make the basis of genetic resources of animal husbandry of the state. Their use promotes recovery of separate branches, in particular sheep breeding, and others -to increase production of highprotein food stuffs, including produce of organic direction.

Corresponding Member of NAAS, doctor of agricultural sciences, Ukraine A. Gratylo, candidate of agricultural sciences H. Smenova Ascania Nova Institute of Animal Breeding in the Steppe Regions named after M. F. Ivanov-National Scientific Selection-Genetics Center for Sheep Breeding The purpose. To develop a technique for agro-ecological production of feedstuff for ruminant animals in conditions of bogharic agriculture of the South of Ukraine according to demands of organic farming which will promote deriving of highly nourishing and qualitative vegetable products without pollutants. Methods. Field and laboratory trials. Results. Use of perspective innovative grades of forage grasses and biological preparations promoted an increase of yield of perennial forage grasses, drought-enduring annual forage crops and as a result deriving pollution-free feedstuff. The content harmful matters, pollutants and heavy metals in samples of the gained feedstuff did not exceed maximum concentration limit. Conclusions. The technique of agro-ecological production of feedstuff is developed for ruminant animals according to demands of organic farming in conditions of bogharic agriculture.
