- Abstract
Mitochondria play an important role in the motility and fertility of sperm by providing energy for metabolism. Therefore the mitochondria integrity is a vital criterion for grading the quality of sperm. This study was conducted to monitor the 24 batches of performance-testing boars including 1,061 Duroc, 420 Landrace and 161 Yorkshire breeds from 2016 to 2018. The semen was collected from boars by 20 days before the auction and stored at 17°C. In consequence, the semen was analyzed by the flow cytometry, at least 5,000 sperms were checked for the integrity of mitochondria to distinguish the sperm productive capability of young boars. Eventually, the correlation between the maturation of sperm and the feed conversion ratio was clarified and it could be the reference for the selection of breeding pigs.
