What is Laminitis ?
Laminitis , in its simplest form , is inflammation of the sensitive layers ( laminae ) of the hoof resulting in pain , inflammation and , in some cases , permanent damage to the laminae . The laminae are interwoven specialised layers of tissue that suspend the pedal bone within the hoof . In very mild cases , appropriate treatment will resolve the problem with no lasting effect . If the inflammation is more severe and progressive , the sensitive laminae may lose their blood supply , resulting in loss of support between the pedal bone and horny hoof wall . This can lead to the separation of the pedal bone from the hoof with rotation and / or sinking of the bone within the hoof . In severe cases , penetration of the sole by the tip of the pedal bone can follow , with fatal consequences .
In this issue Cavalor Equine Nutritionist , Fien Demeyere provides advice on caring for the laminitic horse and pony by answering some commonly asked questions .
What are the typical signs of laminitis ?
When horses suffer from laminitis , the main symptom is painful hooves . Laminitis causes difficulties in turning , and many show a typical laminitic stance where they lean back on to their hind legs . A short and painful walk is also evident .
The inflammation also causes increased hoof temperature , and horses with laminitis are more prone to white line disease and blisters .
What lifestyle should be adopted for the laminitic ?
The most important way to prevent laminitis is to monitor what the horse eats , especially for fructans , the sugars found in grasses .
Along with fructans , avoid sugar and starch ( maximum 1g / kg body weight per meal for Irish Draught horses and maximum 1.5g – 2,5 / kg body weight per meal for healthy horses ) and excess protein . Sensitive horses need to be fed most of their energy in the form of fibre and fats . Dry hay , beet pulp , lucerne , and oils can be used here . Limit the amounts of sugar and starch in the feed ration . In addition to feeding changes , it is important the horse ' s digestive system and metabolism are supported and the
