ATAXIA AND URINARY INCONTINENCE IN CATTLE GRAZING SORGHUM

Abstract

After grazing forage sorghum and grain sorghum regrowth, 54 of 330 breeding cows became ataxic and developed urinary incontinence. Three cows became recumbent, 2 of which died and the third was killed and autopsied. Wallerian degeneration of the white matter of the spinal cord, cerebellar peduncles and cerebellum was seen histologically. Other affected animals began to recover on removal from the crop, complete clinical recovery taking from a few days to over a month. About 5% of affected cows develped purulent cystitis.
