Abstract

|
|
The possibility of embryo transfer technique in pigs to introduce a new genetic material into closed herds for disease control was investigated. The results investigated were as follows: 1. The exhibiting rate of estrus on the administration of altrenogest and PMSG ranged from 83.3 to 100% and the estrus exhibited within 4.0 - 5.3 days after the administration of altrenogest. 2. The average number of ovulation points per pig by the injection of PMSG and HCG were 14.0 - 30.7. 3. The average number of recovered embryos per pig was 15.7, and 72.8% of embryos were recovered. 4. The pregnancy rate of recipients was 63.6% and the survival rate of transferred embryos were 21%. 5. When the 1-cell embryos were cultured for 24hrs, they were all developed. Therefore it is possible to recover and preserve the embryos from the donor pigs which have high genetic ability, and to transfer embryos to recipient pigs which are separated from donor pigs in Korea.
