LAMINITIS IN A MANGALARGA MACHADOR MARE ATTENDED IN THE MUNICIPALITY OF GUIMARÂNIA - MG: case report

Abstract

Laminitis is inflammation of the laminae of the hoof due to reduced blood perfusion leading to loss of connection between the hoof and the dermal lamina. It can be caused by several factors such as septicemia, dietary changes, conditions in the intestinal tract and metabolic changes. This research aimed to report a case of a horse with chronic equine laminitis and review the literature regarding the disease, highlighting its etiology, symptoms and treatment and ways of preventing the disease. Through the anamnesis, it was presented by the owner that the horse manifested pain in the right forelimb, lameness, reluctance to walk and remained in lateral decubitus. During the general clinical examination, it was noted that the animal had hoof hyperthermia, an increase in the palmar digital pulse and the animal's reluctance to move. The diagnosis was defined by radiography, which revealed chronic laminitis in the right forelimb, rotation of the third phalanx and sinking of the hoof's corneal casing. The treatment was based on corrective trimming, the use of orthopedic boots made of synthetic plaster and silicone, phenylbultazone, amitriptyline, omeprazole, firocoxib, gabapentin associated with a diet of only roughage grass, which leads to a favorable prognosis. The use of phenylbutazone associated with gabentin and amitriptyline were efficient in controlling chronic pain, enabling the animal's rapid recovery. The therapeutic association with a diet with a higher roughage content, regular trimming and the use of heart-shaped horseshoes provided greater comfort and stability for the animal, allowing the horse to return to sporting activities in a short period of time.
