摘要
In this study, purebred Mongolian cattle were treated with a series of technical means including superovulation, artificial insemination, non-surgical embryo flushing, embryo grading and embryo cryopreservation, aiming at exploring a set of mature, stable production and breeding program for purebred Mongolian cattle embryos. The results showed that the optimal dose of FSH for superovulation of bred Mongolian cattle was 410 IU; the optimal dose of FSH for superovulation of muhiparous Mongolian cattle was 440 IU. Bred Mongolian cattle exhibited higher average number of available embryos and embryo utilization rate compared with muhiparous Mongolian cattle, but the latter exhibited higher average number of embryos recovered.
