Vi hade ett lamm som blev som du beskriver ditt. Efter mycket letande hittade vi en beskrivning från NZ som handlade om "Vita muskelsjukan" som beror på selen och E-vitamonbrist. Hon fick två sprutor av vet med just selen och vit E och blev botad.
Hoppas det kan hjälpa ditt lamm
White muscle disease
(WMD, utritional muscular dystrophy, nutritional myopathy, stiff lamb disease)
White muscle disease is a degeneration of the skeletal and cardiac muscles of lambs. It is caused by a deficiency of selenium, vitamin E, or both and can be a problem wherever selenium levels in the soil are low or the diet is deficient in selnium. Symptoms are stiffness of the hind legs with an arched back and tucked in flanks. Treatment is the administration of selenium and vitamin E by injection.
Feed rations should be evaluated to determine if they are providing adequate levels of selenium and vitamin E. If dietary levels of selenium are inadequate, lambs can be given an injection of selenium and vitamin E shortly at birth. Dietary supplementation of selenium is usually preferred to selenium injections.
