What is the most common way extended boar semen is stored?

The most common way extended boar semen is stored is in a fresh or liquid state at a temperature between 60-65°F. This temperature range is optimal for maintaining the viability and motility of sperm cells for a limited duration, usually up to several days. Extended boar semen is often diluted with a suitable extender to preserve the sperm and enhance longevity while still allowing for successful fertilization when used for artificial insemination.

When stored at this temperature, the sperm cells remain active and can be used effectively within a few days of collection. This method helps ensure the semen retains its quality and viability, which are crucial for successful breeding.

Other storage methods, such as freezing at below 0°F, are less common for boar semen because freezing can cause damage to sperm cells, impacting their viability. Similarly, storing in a solid state at room temperature is not practical for maintaining sperm health, and using a glass container at 40°F does not align with the best practices for boar semen storage.
