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.
