Acquired equine polyneuropathy (AEP) is a devastating neurologic disease affecting Nordic horses. Characteristic histopathological changes have been shown in the peripheral nerves of horses euthanized due to the disease. These include re- and demyelination as well as hypertrophy of perikaria and proteinaceous inclusions in the myelinproducing Schwann cells. The hypothesis is that an unknown factor, possibly from forage, disrupts the Schwann cell metabolism. Further studies is needed in order to elucidate the aetiology, but the availability of nervesamples is limited as they need to be sampled in immediate association with euthanasia. Transport to pathology units is mostly not feasible due to the severity of clinical signs, making collected samples very valuable. To overcome this challenge we intend to establish Schwann cell cultures, allowing freezing and thawing for further studies. The method is already established at NMBU for dogs and will be applied in affected and control horses.
Acquired equine polyneuropathy (AEP) er en dramatisk nervesykdom som rammer nordiske hester. Det er påvist karakteristiske histopatologiske forandringer i de perifere nervene på hester avlivet pga sykdommen. Disse inkluderer re- og demyelinisering, samt hypertrofi av perikaria og proteinlignende inklusjoner i de myelinproduserende Schwanske cellene. Hypotesen er at en ukjent faktor, muligens fra fôret, påvirker metabolismen i de Schwanske cellene og fremkaller forandringene. Det er nødvendig med videre studier for å kunne belyse årsaksforholdene, men begrenset tilgang på prøver har vanskeliggjort dette. Prøvene må tas ut i umiddelbar tilknytning til avlivning og mange AEP affiserte hester kan ikke transporteres til patologi-enheter. Prøver som tas ut er dermed svært verdifulle. Ved å dyrke Schwanske celler i kulturer vil dette problemet omgås fordi man kan fryse og tine dem opp igjen til videre undersøkelser. Metoden er alt etablert på NMBU for hund og vil benyttes i studien på hest.

The most recent carbon footprint of Swedish pig production was presented in 2009, and no full LCA have been published in 15 years. In recent years major improvements have occurred in Swedish pig production and an updated environmental profile for Swedish pork is needed. The project will identify …

During the last decade, neonatal porcine diarrhoea (NPD) has become an increased problem in Swedish herds. Clostridium (C.) perfringens type A (CpA) and C. difficile (Cd) have been highlighted as causes of NPD but their importance has also been questioned. We have previously demonstrated that CpA …

Mixed leys are among the most important crops in northern Sweden for the dairy production. Mapping the within and between fields variability of the biomass, nitrogen (N) uptake and potentially also forage quality (digestibility and neutral detergent fibre) would help farmers to optimise their …

Flea beetles are serious insect pests in spring oilseed rape. After neonicotinoid seed treatments were restricted, no effective chemical control methods are currently available for flea beetle control. Crop protection has therefore become a serious limiting factor for growing the crop. In an …

In nature, piglets are exposed to a wide range of bacteria that promote a balanced (healthy) gut microbiota. On the farm, routine cleaning can limit exposure to beneficial bacteria leading to an unbalanced gut microbiota. An unbalanced gut microbiota increases the risk of health problems and alters …

Motor laterality, such as left or right-handedness, is a well-known asymmetric phenomenon in both humans and animals, incl. horses. Concurrently, lameness caused by orthopaedic injury is a common cause for asymmetry. In our study of riding horses in training, 73 % had motion asymmetries, warranting …
