摘要：
Between February and September, 1991, 31 cows and heifers of 6 farms in Mecklenburg-Vorpommern and Hessen were superovulated, inseminated and available embryos transferred to heifers of the German Black Pied breed. 20 of the animals were cows (18 Galloway, 3 Hereford). Of these, 11 (55 %) showed a positive reaction after hormonal treatment. Breed distribution of the 11 heifers was 8 Galloway and 4 Hereford. 7 of the heifers (87.5 %) showed a positive reaction after hormonal treatment. Pregancy resulted in 40 % (cows) and 30 % (heifers), respectively.
