In a study on Improved Wallachian sheep, researchers tested the semen quality of 15 male sheep without infections. They used a system to see how the sperm moved and another method to check if the sperm were alive or dying. The results showed that the sperm had good motility, with most of it moving well. They also found that a high percentage of the sperm were alive, while only a small amount was dying. This suggests that the semen from these sheep could be used for artificial insemination or frozen for preserving genetic material. More research with larger sample sizes and different methods is needed to fully understand the quality of the semen.
