Area of Science:

  • Veterinary Science
  • Reproductive Biology
  • Animal Science

Background:

  • The cervix presents a significant barrier to non-surgical embryo transfer in pigs.
  • Existing methods often require surgical intervention, increasing risks and costs.

Purpose of the Study:

  • To develop and evaluate a novel instrument for non-surgical embryo transfer in swine.
  • To assess the efficacy of this instrument in achieving uterine horn embryo deposition and subsequent pregnancy.

Main Methods:

  • A four-part instrument was designed, including a modified spirette for cervical manipulation and a specialized curved-tip tubing for navigating the cervix.
  • Embryos (4-cell to blastocyst) were surgically collected and transferred non-surgically within 5 hours.
  • A testing bar ensured correct placement at the uterine bifurcation.

Main Results:

  • The instrument successfully facilitated the delivery of embryos into the uterine horn lumen in recipient sows.
  • Non-surgical embryo transfer resulted in pregnancies in 5 out of 16 recipients (31%).
  • Pregnant sows farrowed an average of 6.2 piglets per litter.

Conclusions:

  • The developed non-surgical embryo transfer instrument is effective and simplifies the procedure in swine.
  • This technique has the potential to advance swine breeding programs and reproductive research.
