34 four-day-old embryos were collected surgically from 5 Simmental and 3 German Yellow heifers. The embryos were transported by air and were surgically transferred into recipient cows 4-121/2 h later. 19 recipient cows were diagnosed pregnant approx. 50 days after transfer. If embryos classified as abnormal were excluded, the pregnancy rate was 18/27 (67%).
