For the purpose of obtaining the artificial twin birth in the transplanted Korean native cows, non-surgical obtaining of the fertilized eggs and their transplantations were performed. The results were as follows: 1. Average six eggs per donor were ovulated and 65% of them were recovered by non-surgical technique. 2. Eighty two percent of eggs recovered were found to be morphologically normal and were at 4-32 cell stage, respectively. 3. Seventy five percent of cattle treated with prostaglandin F₂α were synchronized in their estrus within 4 days after administration. 4. No twin fetation was obtained from the recipients which received fertilized eggs.
