Liquid nitrogen

LIQUID NITROGEN

  • Importing frozen semen with the aid of liquid nitrogen as the refrigerant is being favored in areas where dry ice is not obtainable, where the nitrogen is available at a reasonable price, and where the electric current is not dependable.
  • The major advantage of frozen semen is its capacity to remain uninfluenced over long distance transport.
  • Another most important advantage is its storage potential extending over several years and the semen may be available even after the death of the bull.
  • For storage and transportation of frozen semen, various sizes of liquid nitrogen containers are available. The frozen semen can be transported through road, rail or air.

It is advantageous if it takes less time to reach the place with minimum jerks during transport.

  • This depends upon distance and availability of transport facility.
  • While transporting frozen semen the temperature should be maintained -196 ⁰ C.
  • The liquid nitrogen holding capacity and evaporation rate depends on the size and type of container.
  • The liquid nitrogen should be topped up during the transport of straws.
  • The wooden crate or similar protective device like hard board or card board may be used during transport of semen to avoid shock to the container.
