    Uittreksel

    This study aimed to evaluate the possibility of reducing boar taint in boars (PiétrainxHybrid) by addition of different feed ingredients (raw potato starch (RPS) 10%, raw potato starch 10%+wheat bran 5% (RPS+WB), lupins 10%, inulin 5%, clinoptilolite 1%) to a standard diet over a period of 4-6 weeks before slaughter. Control boars (CBOAR) as well as barrows were fed the standard diet. Efficacy of the different feed ingredients was evaluated by different boar taint detection methods: hot iron method, consumer panel, expert panel and laboratory analysis. According to all detection methods, clear differences were noticeable between boars and barrows. No differences in boar taint incidence were found between the boars on the different dietary treatments as assessed by consumers, experts, hot iron method or the concentration of skatole in fat. A significant effect on indole level was found, but no further differentiation could be made. The concentration of backfat androstenone was significantly higher for the inulin and control boar group compared to the lupin group. In conclusion, none of the feeding strategies tested in this study reduced boar taint in boars at the given percentages.
