The swine industry relies on high-quality pig semen because it is crucial for efficient production. To ensure quality, semen is evaluated immediately after collection, including how well the sperm moves (motility).Because semen is often stored for several days before use, its quality can change.
In our study, we looked at the genetic factors that influence sperm movement in both fresh and stored semen. While genetics play a major role in the motility of fresh and stored semen, our study indicates that fresh semen motility is a different trait when measured after storage.
By understanding these differences, we can improve breeding programs and rethink sperm motility as a test of endurance, not speed.
