Abstract

This study focuses on 100 boars from three Pietrain varieties: 74 V1, 10 V2 and 16 V3. On average, data wererecorded on 90 ejaculates collected in artificial insemination centers and boar taint measured on 15.4 entiremale offspring, half purebred and half Pietrain × Large-White type. Offspring were reared at INRA UETP(Le Rheu, France) up to 110 kg. Boar taint risk was assessed by androstenone and skatole measurements infat collected at the slaughterhouse. Sperm production data were corrected for the production site, the age andthe collection frequency using a generalized linear mixed model to estimate an average sperm productioncount per boar and ejaculate. Boar taint odor risk was on the whole low in the tested population. Consideringthe three Pietrain varieties altogether, boars with the highest sperm production had a lower proportion ofoffspring without risk of odor compared to boars with low sperm production: the boars ranked in the topquartile of sperm production had 14% less offspring without odor (i.e. androstenone
