| 1. Dominant females do not decrease the skatole and androstenone concentration in entire male pigs being dominated during the growth period from 50-100 kg liveweight (see fig. 1 and 3). 2. The amount of entire male pigs having higher skatole concentrations in blood – corresponding to skatole in backfat > 0.15 µg/g – are surprisingly high at 50 kg and 75 kg liveweight compared to 100 kg (10, 9 and 13 entire male pigs). 3. Furthermore it is not the same pigs having high skatole concentrations during the period from 50 over 75 to 100 kg liveweight. 4. The crossbreed HxLYD had significant higher skatole concentration in backfat at slaughter (100 kg liveweight) compared to the crossbreed YDxLYD (P<0.05)(see fig. 2). However, there was no significant... |

| 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 |

| 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,... |

| Skatole, androstenone and other compounds such as indole cause boar taint in entire male pork. However, female pigs also produce skatole and indole. The purpose of this experiment was to minimise boar taint and increase overall impression of sensory quality by feeding entire male and female pigs with fibrerich feedstuffs. The pigs have been fed three organic diets for either 1 or 2 weeks prior to slaughter of which two diets contained different fermentable fibre-rich feedstuffs – 10–13.3% dried chicory roots or 25% blue lupines. These two treatments were compared with pigs fed with an organic control diet for either 1 or 2 weeks prior to slaughter. Lupines significantly reduced skatole in blood and backfat for both genders after 1 week. Moreover, lupines... |

| Bulk-tank milk was collected every second month (in 2007) from 32 farms in Middle Norway to examine the effect of grassland management and farming system on milk composition. Sixteen farms with organic farming system were paired with 16 farms with conventional farming system. In both farming systems, 9 farms had short-term rotational grassland and 7 farms had long-term grassland. Milk fatty acid (FA) composition and milk concentration of α-tocopherol, β-carotene, retinol,phytoestrogens and selenium were analyzed. Only small differences were found in milk composition from farms with different grassland management, except for the concentration of phytoestrogens and selenium that were highest on farms with short-term grassland. Milk FA composition, milk... |

| Milk samples from sixteen Norwegian Red dairy cows grazing mixed swards of either grass-red clover (GR) or mixed swards of sown and unsown species of grass, clover and other herbs (GCH) were collected during four periods. Both pastures were organically managed. Pasture botanical composition had no effect on milk fat, protein or vitamin concentration and only minor effects on fatty acid composition. Milk from GR had higher concentrations of the phytoestrogens equol, genistein and biochanin A than the milk from GCH. Concentrations of equol in milk from GR were higher than concentrations reported from experiments with red clover silage. The oxidative stability of the milk lipids was not affected by pasture type. |
