The purpose of research - the study of biological patterns of influence of the freezing, the effects of hormones and techniques of culture in vitro for biological objects and the development on this basis of modern methods and techniques of reproduction of sheep. Research methods - a microscopic, cultural, cytogenetic and statistical. It were investigated the action of certain substances and procedures of deep freezing on the morphological and physiological parameters of sperm, neurotrophic substances epinephrine on the folliclogenesis in the sheep ovary, it were developed techniques and ways to improve the effectiveness of deep freezing of ram semen, the scheme of hormonal stimulation of sexual hunting and superovulation, perfected a technique to obtain embryos from intravitaly retrieved sheep oocytes. Using the developed techniques and methods provide a more effective application of biotechnological methods of sheep reproduction by 10-15%. Field of using - a biotechnology, sheep breeding.
