“…The dystrophogenic property of polyunsaturated fatty acids has been demonstrated experimentally by a number of workers (Obel, 1953;Lannek et al, 1961;Lindberg and Orstadius, 1961;Orstadius, Nordstrom and Lannek, 1963;Tanhuanpaa, 1965). Nutritional muscular dystrophy can be produced experimentally in pigs by feeding grain that has been associated with natural outbreaks (Thafvelin, 1960;Lannek et al, 1960).
