New developments in muscle pathology: Nutritional myopathies including “muscular dystrophy” or “white muscle disease”

Abstract: Dietary deficiencies of vitamin E and/or selenium may result in muscular degeneration in young calves and older growing animals. The preservation and storage of moist grain with propionic acid reduces its vitamin E content; feeding such grain to older animals may predispose them to the myodegeneration which often occurs following their return to spring grazing and unaccustomed exercise. Cold or wet windy weather may be another predisposing factor. Deficiency of vitamin E or selenium probably results in peroxidative damage to cell membranes which precedes tissue and muscular degeneration.

Congenital nutritional myodegeneration (white muscle disease) in a red deer (Cervus elaphus) calf.

Abstract: CASE HISTORY A 5-day-old red deer calf was submitted with tachypnoea and dyspnoea, and was reluctant to move. CLINICAL FINDINGS: Muscular damage was established via elevated creatinine phosphokinase (CPK) activities (5,000 U/L), while concentrations of Se in whole blood were low (24.8 nmol/L). The animal died despite treatment with penicillin-streptomycin and 0.1 mg/kg Se/vitamin E administered by S/C injection. DIAGNOSIS: Necropsy and histological examination of cardiac and skeletal muscle confirmed the presumptive diagnosis of congenital white muscle disease (WMD). Prophylactic administration of a Se/vitamin E commercial preparation (as above) to another calf born in the same herd one month later was associated with good health and apparently normal growth and development. CLINICAL RELEVANCE: Congenital WMD due to Se deficiency can be fatal in red deer calves. However, prophylactic administration of Se and vitamin E to neonatal calves may be beneficial for neonatal red deer calves.
