Abstract
The use of chemically defined media for embryo production is an important factor relevant to obtaining optimal culturing conditions and to minimize the risk for infection. In the present study the influence of chemically defined components in media for culturing and cryopreservation to the growth and development of sheep embryo will be investigated. In vitro and in vivo viability of embryos after cryopreservation using slow freezing and vitrification will be tested. After the birth of lambs from in vitro cultured embryos ''large offspring syndrome'' will be evaluated. The results obtained from the proposed study will lead to better understanding of chemically defined media used for in vitro culturing, slow freezing and vitrification of sheep embryos. The improved technology of embryo production and embryo transfer will be used in a breed preservation program (gene bank) of autochthonous animals and also for the genetic improvement of livestock.
