The efficiency of embryotransfer in cattle in Poland has been described. The number of superovulated cows in the years 1997 and 1998 was 736 and 390 respectively. 15 to 35.9 percent of all flushed donor cows were meat breeds, especially Limousine, Chereford and Piemontese. The average number of total embryos and oocytes and/or transferable embryos in 1997 and 1998 was 5.95 and 6.79 and/or 3.37 and 3.81.Those results have been disscussed. The number of the transferred fresh embryos was in the compared years 1127 and 627 respectively, and frozen 1651 and 945. Pregnancy results after the direct transfer and the transfer of fresh and traditionally frozen and thawed embryos were 42.9 to 43.7% and 47.0 to 55.0%.
