| Two similar trials were carried out to examine how dietary inclusion of an easily fermentable carbohydrate source such as chicory roots (Cichorium intybus) may effect established and establishing helminth infections in pigs. In the first trial varying feeding periods with crude chicory roots naturally rich in fructans (primarily inulin) were tested whereas crude chicory roots were compared with dried chicory roots and purified inulin in the second trial. In both trials pigs were infected with 3000 O. dentatum L3-larvae while fed a traditional standard diet. When the infections were well established and patent, experimental diets were introduced and the faecal egg counts monitored. Two weeks before the pigs were slaughtered all animals were infected with... |

| Two diets with contrasting digestibility was formulated - the diet containing resistant carbohydrates (Diet 1) was based on triticale, barley, rapeseed cake and silage as the main ingredients while the diet with fermentable carbohydrates (Diet 2) was based on triticale, barley, blue lupines and chicory roots. Assuming that the pigs will consume approximately 7 % of the dry matter from silage and 15 % from chicory roots, the content of feed units for pigs (FEs) will be 0.96 and 1.09 FEs in Diets 1 and 2, respectively. After two weeks of adaptation, the pigs were infected with 2000 infective eggs of T. suis. Faecal egg samples were taken twice weekly to determine the number of parasite eggs excreted. All the pigs were slaughtered 12 weeks post infection... |

| 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. |

| 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. |

| Environmental as well as cultivation factors may greatly influence the chemical composition of plants. The main factors affecting chemical composition of foodstuff is level and type of fertilizer (conventional and organic cultivation systems), location or soiltype and year of harvest. Organic foods are defined as products which are produced under controlled cultivation conditions characterized by the absence of synthetic fertilizers and very restricted use of pesticides. Dietary carbohydrates constitute a major fraction of most feedstuffs and can be divided according to glycosidic linkage into sugars (mono- and disaccharides), oligosaccharides, starch and non-starch polysaccharides (NSP). The bulk of disaccharides and starch will be broken down by the... |

| Two diets with contrasting fermentability were formulated. Diet 1 containing resistant carbohydrates was based on triticale, barley, rapeseed cake as the main ingredients supplemented with grass clover silage. Diet 2 containing fermentable carbohydrates was based on triticale, barley, blue lupines and dried grinded chicory roots. The two diets were fed to seventy-two pigs tested negative for T. suis and swine dysentery were divided into 8 groups (A-H) according to weight and sex as follows: Group A: Diet 1, T. suis and B. hyodysenteriae; Group B: Diet 2, T. suis and B. hyodysenteriae, Group C: Diet 1, B. hyodysenteriae; Group D: Diet 2, B. hyodysenteriae, Group E: Diet 1, T. suis; Group F: Diet 2, T. suis; Group G: Diet 1, control, and Group H: Diet 2,... |
