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 .

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
