| description | The equine hoof is often manipulated in purpose to achieve a better stride or to reduce the weight on damaged tissue. The living tissue in the hoof can't store energy as glycogen and is therefore depending on a continuous supply of glucose for its energy production. The purpose of the study was to determine if wedging (i.e. elevating) the heel could influence the hooves glucose and lactate consumption/production.
Five standardbred horses were trained to trot on a treadmill without getting physical or mentally tired. Before the experiment started three catheters were placed in vena digitalis lateralis (digital vein), vena jugularis (jugular vein) and arteria temporalis superficialis (facial artery). The horses trotted for three periods each on the treadmill with a high heel wedge, a low heel wedge or with a standard horseshoe in a randomized order. Blood was, simultaneously, collected via the catheters before and after each period. The blood was analyzed with reference to glucose and lactate.
There was no significant difference in lactate or glucose as a result of exercising with heel wedges. However, the overall trend was that the lactate production increased with work while the glucose levels were reduced. A trend could also be seen in the glucose values in that the high heel wedge gave the largest reduction in glucose in the artery blood. It was relatively seen a smaller increase in the lactate levels in the hoof than in the rest of the body. The amount of exercise gave significant difference in lactate levels, i.e. the fact that the horses were running on the treadmill gave significance but which wedge they used made no difference. The lactate levels were at all sampling occasions significantly higher in digital venous blood than in blood from the jugular vein and the facial artery. |

Hästens hov manipuleras ofta i avsikt att åstadkomma ett förbättrat steg och att minska belastningen av skadad vävnad. Hovens levande vävnader kan inte lagra socker i form av glykogen och är, liksom många andra kroppsvävnader, beroende av en kontinuerlig glukostillförsel för sin energiproduktion. Målet med studien var att se om en uppkilning av trakten påverkade hovens glukos och laktat konsumtion/produktion i samband med arbete. Fem stycken varmblodiga travare tränades till att trava på rullmatta utan att bli fysiskt eller psykiskt trötta. Inför försöket lades permanentkatetrar i vena digitalis lateralis (digitalven), vena jugularis (jugularven) och arteria temporalis superficialis (facialisartär). I lottad ordning sprang hästarna i tre omgångar på rullmattan med antingen en hög kil, en låg kil eller ingen kil alls. Före och efter varje omgång togs blodprover simultant från permanentkatetrarna. Blodproverna analyserades med avseende på glukos och laktat. Ingen signifikant skillnad kunde ses i laktat eller glukosnivåer av att hästarna sprang med traktkilar på rullmattan. På glukosvärdena sågs en trend, som var nära att ge signifikans, i det att den höga kilen orsakade den största minskningen i det arteriella blodets glukosnivå. Den övergripande totala trenden var att laktatproduktionen ökade vid arbete på rullmattan medan glukosnivåerna minskade. Relativt sett var det en mindre laktatökning i hoven än i övriga kroppen. Att hästarna sprang på rullmattan medförde i sig en signifikant skillnad i laktatnivåerna men vilken slags kil de hade på sig spelade ingen roll. Laktatvärdena var i likhet med tidigare studier signifikant högre i hoven än i både jugular och facialisartärblodet. 2007-12-19 Other NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/11729/1/borg_h_171116.pdf Borg, Hanna, 2007.
