| Boar taint is an off-flavour of pork caused primarily by skatole and, androstenone. Pig off-odour and flavour mostly caused by higher skatole concentrations in backfat. It is a problem in all types of pork production and is not restricted to entire male pigs. If uncastrated, 5-10% of Danish entire male pigs (100 kg liveweight) have > 0.25 ppm skatole in backfat and are then classified as boar tainted, having a markedly reduced value. Even backfat skatole values above 0.15 ppm enhance the off-odour for skatole sensitive consumers. An alternative way to reduce high skatole concentrations may be feeding with fibre-rich feedstuffs. This idea is based on previous studies which have demonstrated that 10% dried chicory or more in the feed reduces skatole in... |

| Sukkerstoffet inulin er kendt for at kunne nedsætte dannelsen af skatol hos svin. Det skyldes at inulin ændrer tarmfloraen, så bakterier der danner skatol bliver holdt i skak. Samtidig bevirker den ændrede tarmflora at grisene får færre indvoldsorm. Inulin er imidlertid for dyrt til, at det kan betale sig at bruge det i svinefoder. Cikorierødder indeholder inulin og en række andre kulhydrater plus sekundære metabolitter. Derfor har vi undersøgt om cikorierødder kan erstatte ren inulin og derigennem mindske ornelugten, forbedre smagen og nedsætte grisenes smitte med sygdomsfremkaldende parasitter og bakterier. |

| The carbohydrate inulin is known to reduce the production of skatole in pigs. This is caused by inulin changing the intestinal flora, so that the bacteria that produce skatole are held in check. This change in intestinal flora also reduces the number of intestinal parasites in the pigs. However the high cost of inulin makes its use in pig feed impractical. Chicory root contains inulin and a series of other carbohydrates and secondary metabolites. Therefore we have examined whether chicory root can replace pure inulin and thereby reduce boar taint, improve the taste of pork and reduce the infection of pigs with pathogenic parasites and bacteria. |
