Improvement of female reproductive potential by in vitro embryo production technology
Committee on Biotechnology PAS ; Institute of Bioorganic Chemistry PAS
Two procedures for mass production of embryos for use in cattle breeding schemes are nowavailable, namely multiple ovulation + embryo transfer and more recently in vitro embryo production. Hormonal treatment for multiple ovulation, nonsurgical embryo collection and embiyotransfer are widespread techniques to obtain more offspring from genetically superior cattle(MOET program). However, the costs can be considerable and the yield of embryos is highlyvariable. Research during the past decade has been focused on embryo production in vitro withoocytes from slaughterhouse ovaries and has tremendously succeed. Presently ultrasound guidedtechnique for oocyte collection in living animals has been developed. However, both discussedprocedures allow to use only a tiny part of a high follicular capital of ovary. Bovine ovarycontains many thousants of primordial follicles, but the vast majority become atretic duringgrowth and maturation. Recently is developed a technique for in vitro growth of preantral folliclesrescuing them against atresia. It would offer a significant means for the propagation of valuableanimal stocks, and would be an addition to the methods already available for use in embryoproduction in vitro, since it would supply a large and uniform population of oocytes from genetically superior animals.
