| I et 2x2 forsøgsdesign er økologiske slagtesvin givet slagtesvinefoder med to niveauer af protein (norm og 85% af norm) samt 0% og 25% lupin. Hvis proteinindholdet i foder til økologiske slagtesvin nedsættes til 85% af gældende norm, falder kødprocenten op til 1% og indholdet af intramuskulært fedt (IMF) i kammuskel stiger med 0,5%. Dryptab, slut-pH, temperatur 24 timer efter slagtning, pigmentindhold og konsistens (hårdhed) for kammusklen påvirkes ikke. Indholdet af skatol i rygspæk falder lidt. Indholdet af mættede fedtsyrer i rygspæk stiger, indholdet af monoumættede fedtsyrer ændres ikke, mens indholdet af flerumættede fedtsyrer falder, hvilket betyder at jodtallet (fedtets umættethed) falder fra 67 til 65. Spisekvaliteten udtrykt ved en sensorisk... |

| Ornelugt i svinekød kan begrænses ved to ugers fodring med 25 pct. lupiner i foderet. Ornelugt er en afvigende lugt og smag, som findes hos 5 til 10 procent af danske hangrise ved en vægt omkring 100 kg. Imidlertid vides det, at sogrise og galte i flere forsøg også har "ornelugt". Eller nærmere betegne, det som nogle forbrugere opfatter som griselugt og afsmag i kødet. Problemet skyldes først og fremmest stoffet skatol. |

| Boar taint in entire male pork is caused by skatole and andros-tenone and other compounds such as indole. However, female pigs also pro-duce skatole and indole. The purpose was to minimise boar taint related to skatole by feeding entire male and female pigs with fibre-rich feedstuffs. An organic, 10% dried chicory or 25% lupine diet was applied for either 7 or 14 days before slaughter. Lupines significantly reduced skatole in backfat for both genders whilst chicory showed no significant differences in this re-spect. From a sensory perspective, chicory and lupine reduced boar taint since odour and flavour of manure related to skatole and urine associated to androstenone were minimised. The level of boar taint in the entire male pigs was mainly reduced after... |

| 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... |

| Prebiotics are non-digestible oligosaccharides acting by stimulating the growth of bacteria being beneficial for the gastrointestinal health of the host and may serve as a means to control pathogens. This study aimed to assess if inclusion of chicory or lupins (prebiotics) in the diet of pre-slaughter pigs for just 1 or 2 weeks could change the composition of their intestinal microbiota and help to lower the level of the important foodborne pathogen Campylobacter spp. The study showed that even a short-term alternative feeding strategy with prebiotics in the diet of pre-slaughter pigs elicited changes in the composition of intestinal microbiota with stimulation of the growth of bifidobacteria in caceum and a reduction of the Campylobacter spp. excretion... |
