【 摘 要 】

Reproductive performances of the boars used in commercial artificial insemination depend on semen quality assessment. The aim of this study was to analyze in vitro quality of the main commercial swine breeds’ (Large White, Landrace, Pietrain and Duroc) semen parameters including volume, concentration, motility, viability, acrosome integrity, functional integrity (hypo-osmotic swelling test and thermoresistance test) and DNA integrity (DNA fragmentation index) in order to compare them with fertility (conception rate). Significant differences were observed between volume, concentration, progressive motility, viability and morphology of sperm. No other differences were observed in the case of immature sperm, functional and DNA integrity of sperm and conception rate. Between swine breeds there are some differences regarding semen quality parameters, but it is difficult to establish a clear correlation in order to predict semen fertility.
