Liver disease in horses causes complex metabolic disturbances and neurological signs that require careful dietary and medical management to maintain welfare and extend life quality.
Equine liver disease causes significant welfare compromise through multiple mechanisms. Hepatic encephalopathy produces a confused, distressed mental state due to ammonia accumulation. Photosensitivity causes skin pain and blistering in affected horses kept outdoors. Weight loss and muscle wasting reduce condition and comfort. Dietary management with carefully formulated low-protein rations reduces ammonia production and encephalopathy risk. Stable management that prevents sun exposure during photosensitive phases prevents significant additional welfare harm. Regular assessment of neurological status guides management intensity and euthanasia decisions when quality of life deteriorates.
