A Holstein stud bull can produce thousands of doses of frozen semen, which are used to distribute its selected genetics to dairy herds all over the world. The semen quality of stud bulls has an impact on the economics of the breeding centers. Our previous study found that monozygotic twin stud bulls showed different semen quality traits and different transcriptomic profiles in sperm cells. The number of motile sperm per ejaculate (NMSPE) is an integrated trait for assessing sperm motility in stud bulls, which is one of the most important semen quality traits. In the present study, we selected 7 stud bulls that had a high NMSPE (named as H group) and 7 stud bulls with low NMSPE (named as L group) from a Chinese Holstein bull population based on 9 yr of semen quality records. In this study, we investigated the sperm cells transcriptomic differences between the two groups and observed the influences of seminal plasma metabolites on the transcriptomic profiles of the sperm cells. The results showed that the expression level of the differentially expressed genes in the sperm cells is closely related to NMSPE. Our study discovered 14 genes as the potential candidate markers for sperm motility, including FBXO39. Our data provide new insights into the improvement of bovine semen quality traits.
