| 1. The objective of the study was to compare the establishment and effect of Ascaridia galli infections in 4 different layer-lines. 2. A total of 160 birds comprising 4 different commercial layer-lines, ISA Brown, New Hampshire, Skalborg and a cross of New Hampshire(NH) and Skalborg (Sk), were infected with A. galli eggs. The birds were examined for the presence of parasite eggs and parasites at weeks 3, 6 and 9 post infection (pi). 3. At week 6 pi the chickens of the NH line harboured more larvae compared with the three other lines. The Sk line chickens excreted more A. galli eggs throughout the study compared with the other lines. Female worms in the Sk line were more fecund than the worms in the other lines. Male and female worms recovered from the Sk... |

| Boar taint is an off-flavour of pork caused primarily by a microbial breakdown product, skatole and a testicular steroid, androstenone. As skatole is produced in the large intestine from tryptophan, it is possible that some "bioactive" ingredients could modify protein fermentation and, in the process, diminish boar taint. The aim of this study was to examine the effect of inulin-rich chicory roots (Cichorium intybus L.) on boar taint. In the first of three trials individually penned, entire males and females were given an organic concentrate in which 0·25 of the daily energy intake was replaced with crude chicory roots for 9 or 4 weeks prior to slaughter. In the second trial, entire male pigs were given diets that included, either crude chicory roots,... |

| It is known that pure inulin a fructooligosaccharide extracted from chicory roots can: – reduce boar taint (skatole in backfat and blood) – reduce parasite infection levels when added to specially composed experimental diets • However, the entire chicory roots may, in comparison to inulin: – reduce boar taint more effectively – improve the taste of cooked meat from both male and female pigs – be more effective against parasites when added to normal diet types – contain secondary metabolites that add to the effect of the inulin – be a cheaper solution |

| Production of bioenergy in organic agriculture may be implemented in the future to reduce the reliance on non-renewable fossil fuels and minimize greenhouse gas (GHG) emissions. Therefore it is important to assess the potential effect this may have on soil quality and biological parameters. This project aims at designing and evaluate a combined concept for biomass and bio-energy production in OA, while considering soil bio-geo-chemical cycling of plant nutrients and biodiversity of the soil microbiota. |
