Surgical and nonsurgical embryo transfer methods in pigs are evolving. Nonsurgical techniques offer improved animal welfare and farm applicability, making them preferable for widespread use in swine reproduction.

Area of Science:

  • Reproductive biology
  • Veterinary medicine
  • Swine reproduction

Background:

  • Porcine embryo transfer (PET) has utilized surgical methods for decades, proving reliable but limited in farm utility.
  • Recent advancements aim to enhance the practicality and efficiency of PET procedures.
  • Minimally invasive endoscopic surgery and novel nonsurgical techniques are emerging.

Purpose of the Study:

  • To review and compare surgical and nonsurgical methods for porcine embryo collection and transfer.
  • To highlight advancements in PET techniques, focusing on farm applicability and animal welfare.
  • To assess the success and feasibility of newly developed nonsurgical procedures.

Main Methods:

  • Review of established surgical embryo collection and transfer techniques in pigs.

  • Description of minimally invasive endoscopic surgical refinements for PET.
  • Analysis of newly developed nonsurgical embryo collection and transfer procedures, noting limitations.
  • Evaluation of the success rates and practical advantages of nonsurgical PET.

    • Main Results:

    • Surgical methods for PET are reliable but not ideal for on-farm application.
    • Endoscopic surgery offers a less invasive surgical alternative for PET.
    • Nonsurgical embryo collection is currently limited to sows with specific uterine horn modifications.
    • Nonsurgical embryo transfer has demonstrated recent success and significant advantages.
    • Nonsurgical procedures are superior in terms of animal welfare and farm-based implementation.

    Conclusions:

    • Nonsurgical embryo transfer methods represent a significant advancement in swine reproduction.
    • These newer techniques enhance animal welfare and are more practical for on-farm use.
    • Further development and adoption of nonsurgical PET could revolutionize swine breeding programs.
