This study was carried out to establish an effective system for embryo transfer techniques by educational-industrial complex. The embryos of Korean Cattle were transferred into a total of 79 recipients. The pregnancy rate were higher in Korean Cattle (38/53, 72%) than Holstein (17/26, 65%) in recipients. However, there were no significantly difference between Korean Cattle and Holstein in recipients. In embryo transfer using fresh embryos (28/39, 72%), the pregnancy rate was slightly higher than frozen-thawed embryos (68%, 27/40). In another experiment, the number of transferred embryos showed no difference in pregnancy rate, but when two embryos (75%, 21/28) transferred, the pregnancy rate was slightly higher than with one embryo (65%, 33/51). In summary, it will be useful to apply effective system for improvement of pregnancy rate and increase of the income in a farmhouse on embryo transfer of Korean Cattle by educational-industrial complex.
