Area of Science:

  • Veterinary Medicine
  • Reproductive Biology
  • Animal Science

Background:

  • Effective artificial insemination in horses relies heavily on proper semen handling techniques.
  • Maintaining semen viability from collection to insemination is paramount for reproductive success.

Purpose of the Study:

  • To review and outline optimal procedures for handling stallion semen for both on-farm use and transportation.
  • To identify critical factors influencing semen quality and survival during storage and transit.

Main Methods:

  • Review of established protocols for semen collection, extension, and storage.
  • Analysis of temperature sensitivity and cold shock effects on stallion spermatozoa.
  • Evaluation of semen processing techniques to reduce seminal plasma and achieve optimal sperm concentration for transport.

Main Results:

  • Skim-milk extender is recommended for stallion semen preservation.
  • Specific sperm concentrations (25-100 x 10^6/mL) are advised for transport.
  • Controlled cooling rates and temperatures (e.g., <10°C for longer storage, Equitainer for >24h transport) are essential to prevent cold shock and maintain viability.

Conclusions:

  • Adherence to meticulous handling procedures, including temperature management and appropriate semen processing, is vital for successful equine reproduction.
  • The Equitainer is a recommended transport container for extended semen shipments.
  • Minimizing exposure to detrimental factors like mechanical damage, light, extreme temperatures, and toxic residues ensures optimal semen quality.
