LAMINITIS REVIEW Has your horse or pony had laminitis? If so you must be aware of the ongoing management practices that are necessary to not only keep the horse sound but to prevent reoccurrence of the condition.

There are a variety of conditions that can cause laminitis (or founder). The “laminae” describes the lining of the hoof wall and “itis” describes a condition of inflammation. Conditions such as grass founder, grain founder,“Cushings Disease” (hairy ponies) or other changes in carbohydrate metabolism can cause laminitis. Also colic, pneumonia severe gastroenteritis and diarrhoea, metritis,retained placenta and supporting limb laminitis can all be the cause of this devastating disease.

* X-rays are an essential for successful management providing a wealth of information. A photo and an X-ray are taken of the same hoof at the same time, then computer software allows us to superimpose the 2 pictures. A report is generated with various angles relating to the position of the pedal bone within the hoof. This information allows assessment of the severity of the condition, prognosis and formulation of a treatment plan.

Farriers have this visual information to help them plan their hoof trimming & shoe selection. You will take home with you a CD of the pictures which you can show your farrier. Corrective shoeing is vital to maintain soundness.

Repeat x-rays are advised at least annually to monitor the pedal bone position and ensure the correct hoof angle is maintained.

* Paddock time must be carefully monitored.During the day grass holds less sugar due to the process of photosynthesis. At night grass has more sugar because the plant is not using its sugars (the plant undergoes respiration at night.) This is why we advise horses and ponies that are in danger of laminitis to be locked up at night. Grazing may also have to be restricted during the day.

* Feed type may have to be restricted to low carbohydrate feed. Luckily we have an array of feeds on the market that we can choose from; diets need to be individually tailored to each horse or pony.

* Exercise is important for ponies and horses who tend to put on weight easily. Once the laminitic condition is managed a controlled exercise regime is necessary.

* Aggressive treatment & Medications will be necessary in the early stages of laminitis for pain relief and to decrease the inflammation occurring within the hoof laminae. Anti-inflammatories, pain relief, drenching and antibiotics may all be required depending on the inciting cause of the laminitis.

* Daily monitoring - you must know how to monitor your horse for pain. Daily monitoring of horses at pasture, checking feet for heat and increased digital pulse, watching out for lameness are all necessary. After rain when new grass appears and lush pasture develops is a critical time of year.

Laminitis is a complex disease requiring knowledge, vigilance & diligence.
