[ Method ] Twenty-four estrus muhiparity Landraee sows provided by Longjing Agricultural Science and Technology Institute were performed embryo transfer surgery, and postoperative effects were observed. [ Result] Totally 11 out of 24 receptor sows were pregnant ; pregnant sows delivered 67 cloned piglets, and the average farrowing rate of sows was approximately 6 piglets/sow. There were 22 mortalities of newborn piglets because of various reasons. [ Conclusion] Embryo transfer technique is an indispensable link in pig production, and an important means of pig breeding and improvement.展开更多
