Laminitis, an extremely painful disease of the equine foot, is most commonly caused by elevated insulin
concentrations in blood (hyperinsulinemia). Therefore, strategies to reduce hyperinsulinemia in horses are warranted.
Studies in obese children with insulin dysregulation and hyperinsulinemia have identified elevated levels of the
hormone glucagon in blood. To identify novel treatment strategies for preventing laminitis we compared insulin
dysregulation in the horse with that observed in humans. We found that horses with insulin dysregulation also had an
excessive glucagon secretion during an oral sugar test in a small pilot study.
If the results of the pilot study hold true also for a larger population of horses, this would be a breakthrough in the
understanding of the pathophysiology of insulin dysregulation in the horse. This opens up for medical treatment of
these horses since there are treatment strategies for an abnormal glucagon response in humans with -cell
dysregulation.
Fång, en smärtsam sjukdom som drabbas hästens hov, orsakas i de flesta fall av förhöjda koncentrationer av insulin i
blodet (hyperinsulinemi). På grund av detta samband finns det ett stort behov av att finna metoder, som minskar
graden av hyperinsulinemi hos häst.Studier utförda på överviktiga barn med störd insulinmetabolism och hyperinsulinemi har funnit förhöjda nivåer av hormonet glukagon i blodet. I likhet med dessa resultat har vår forskargrupp i en mindre pilotstudie visat att hästar med hyperinsulinemi också hade en ökad frisättning av glukagon under ett oralt glukostoleranstest.
Om vi studerar detta samband i en större hästpopulation och då påvisar samma resultat som i pilotstudien, skulle det
innebära ett stor genombrott i förståelsen om hur hyperinsulinemi uppstår hos häst. Det skulle innebära att nya
behandlingsmetoder mot hyperinsulinemi hos häst blir tillgängliga, då det redan finns behandlingsstrategier med
läkemedel vid störd glukagonmetabolism hos människa.

Heat stress is expected to be of major concern in Swedish animal production systems in the future. The air temperatures in parts of Sweden are expected to correspond to today's temperatures in southern Europe, where livestock experience heat stress today. Excessive thermal load affects the welfare …

Poultry have a strong motivation for foraging and spend most of the day pecking and searching for food. In commercial conditions, the birds are fed a pellet diet, which is consumed very quickly. Consequently, hens spend a large part of the day engaging in abnormal non-food related pecking …

According to applicable legislation, manure and digestate must be sanitized in order to prevent disease transmission before they may be merchandised on the open market. Swedish plants currently have the choice between using one of two standard methods (70 °C for 1 h, or 52 °C for 10 h), or carry …
