neuraxial edema

neuraxial edema

a disease complex of newborn calves, recorded only in polled Herefords and their crosses; characterized clinically by extreme extensor spasm if stimulated by touch or lifting to their feet. They appear normal while recumbent, are unable to stand but can suck normally. Two diseases have been identified, inherited, congenital myoclonus and a poorly defined 'congenital brain edema' occurring in horned Hereford cattle. See also maple syrup urine disease.
