Objectives The differences in semen quality of different breeds of boars were studied to improve the level of boar breeding and management. Methods The semen quality data of 247 adult male boars including 73 Landrace pigs, 75 Large White pigs, and 99 Duroc pigs from 51 batches in 32 pig breeding counties in Hunan Province from April 2021 to November 2022 were collected. The differences in semen vitality, deformity rate, and parameters of sperm motility among different breeds of boars were studied with analysis of variance. Results There was no significant difference in the vitality and deformity rate of semen among different breeds of boars. The slow proportion of sperm in Landrace pigs was significantly higher than that in Duroc and Large White pigs. The proportion of sperm rotation in Landrace pigs was significantly lower than that in Duroc and Large White pigs. There was no significant difference in other trajectory parameters. Conclusions The migration rate of sperm in Landrace pigs was lower than that in Duroc and Large White pigs, and the proportion of forward moving sperm in Landrace pigs was higher than that in Duroc and Large White pigs.
