Summary

Artificial insemination (AI) in pigs improves fertility and genetics. New AI methods aim to reduce sperm doses and inseminations for faster genetic gain in swine breeding.

Area of Science:

  • Animal Science
  • Reproductive Biology
  • Swine Genetics

Background:

  • Artificial insemination (AI) is crucial for global swine production, enhancing fertility, genetics, labor, and herd health.
  • AI centers manage boars and semen, enabling selection based on fertility and sperm production metrics.
  • Current AI practices involve specific sperm concentrations and volumes for cervical or intrauterine insemination, with liquid semen viable for 3-7 days.

Purpose of the Study:

  • To explore novel AI strategies for accelerating genetic improvement in pigs.
  • To investigate methods for reducing sperm numbers per dose and the frequency of inseminations.
  • To enhance selection pressure on sires for economically important traits.

Main Methods:

  • Review of current AI protocols in commercial sow breeding.
  • Analysis of emerging techniques for sperm dose reduction and fixed-time AI post-ovulation induction.
  • Evaluation of the impact of these approaches on genetic selection and dissemination.

Main Results:

  • Established AI protocols produce 20-60 doses with 1.5-3.0 billion motile sperm per ejaculate.
  • Semen extenders maintain fertility in liquid form for 3-7 days.
  • New approaches focus on lowering sperm per dose and single, fixed-time inseminations to increase genetic gain.

Conclusions:

  • Reducing sperm numbers and insemination frequency via advanced AI techniques can accelerate genetic progress in swine.
  • These innovations allow for greater selection intensity on sires, disseminating desirable genetic traits more broadly.
  • Optimized AI strategies are key to maximizing genetic improvement in commercial pig populations.
