Analysis of artificial insemination center management factors that contribute to sperm parameters and boar longevity
The results reveal better sperm quality for untreated boars than for PGF2α-treated boars, which might indicate that the underlying fertility of boars necessitating treatment is inferior compared to boars that can be collected without further treatment.
Differences of semen microbiota among breeding boars with different reproductive ages
The semen of older boars contained a higher abundance of harmful bacteria, which contributes to the observed reduction in semen anti-oxidant capacity and overall semen quality in this group.
