Animal in dustry in Korea urgently needs the domestic introduction and the industrial a, pp.ication of embryo transfer technique. Namely, this technique can be utilized effectively, as means of the improvement of livestocks, as means of the increase of meat production, as means of substitute for the livestock import, and dissemination of new breed. However, as this technique avaliable in our country is remaining initial stage, we can not make use of the technique industrially unless we make much improvement as follows; induction of superovulation, non-surgical recovery of embryos, synchronization between the estrus such cycles of donor and recipient, non-surgical transfer of embryos, etc. Simultaneously, the basic studies such as harvesting oocytes from ovary, in vitro culture of oocytes, in vitro capacitation of spermatozoa, cloning by culture of blastomeres and transfer of nuclei, sexing embryo, etc. should not be neglected in order to make the technique of embryo transfer more simple and convenient. For the success of these studies, universities, national and public institutes, large scale cattle farms, and small scale cattle farms should cooperate each other. For instance, universities undertake basic researches, and the national and public institutes a, pp.y the results of the researches to animal industry along with cooperation by large scale cattle farms. By the help of the cooperative organizations, the technique relevant to our environment and farm condition may be able to be finalized, and to be a, pp.ied to samll scale cattle farm. Consequently, being served to stimulate animal productivity, this technique can be contributed to the development of livestock industry in Korea.
