| description | Laminitis is a debilitating disease causing much suffering to horses and ponies all over the world. It is manifested in the hooves as a mechanical failure of the suspensory apparatus between the hoof capsule and the distal phalanx. Due to the weight of the horse the disease may result in a dislocation of third phalanx.
Six healthy standardbred trotters were used in this study on whether standardbreds tolerate forced recumbency as well as Shetland ponies. Recumbency was induced pharmacologically but maintained only by lowering the ceiling height of the box to a height of approximately 125 – 140 % of the horse´s thoracic height. Behavior and bodily functions were observed and recorded during and after the study periods of up to two days. Blood was sampled for serum analyses of CK and ASAT to detect muscle tissue damage.
The results of this study indicate that the increased body weight of Standardbred Trotters when compared to Shetland ponies does not have a negative effect on bodily functions during a limited period of recumbency. All horses accepted the treatment well and no adverse effects were seen during or after the study. |

Fång är en vanlig sjukdom som ofta medför ett stort lidande för den drabbade hästen och inte sällan resulterar i att individens framtida användbarhet påverkas radikalt eller att hästen behöver avlivas av djurskyddsskäl. Sjukdomen medför en hållfasthet – belastningsproblematik i det att det vävnadslager, lamellagret, som binder ihop hovväggen med hovbenet av någon anledning blir försvagat så att det inte längre klarar av att bära hästens vikt. Detta resulterar i att vävnaden slits sönder och hovbenet, som bär hästens vikt, sjunker/roterar ner mot marken. Det har föreslagits att hästar som inte bär vikt på sina hovar under det akuta skedet kan undvika en lägesförändring av hovbenet och därigenom få en betydligt bättre prognos för tillfrisknad. I denna studie undersöktes om friska varmblodiga travhästar, psykiskt och fysiskt, klarar att ligga i en välhalmad box med sänkt tak i upp till 2 dygn. De 6 hästarna lades omkull med hjälp av dissociativ anestesi och därefter sänktes taket ner till 125 – 140 % av respektive hästs bröstkorgshöjd. Beteende och kroppsfunktioner studerades kontinuerligt. För bedömning av muskelpåverkan togs blodprov innan hästen gick in i boxen, direkt efter det att den rest sig upp och 1-2 dagar efter boxvistelsen och blodserumets nivåer muskelenzymerna CK och ASAT analyserades. I överensstämmelse med resultaten i en tidigare studie, som utfördes på shetlandsponnier, bedömdes travhästarnas kroppsfunktioner inte påverkas negativt av att de hålls liggande under en begränsad tidsperiod. Alla försökshästarna accepterade behandlingen väl och inga allvarliga komplikationer uppstod under eller efter försöksperioderna.
