Halogeton Poisoning in Range Cattle

Abstract

Acute Halogeton glomeratus poisoning occurred in 16 of 680 range cattle during and following a trail drive. Signs of toxicosis included posterior ataxia, recumbency, coma, and death. Histopathologically, abundant, refractile calcium oxalate crystals were seen in renal tubules. Inasmuch as the plant is generally unpalatable for cattle, poisoning in this case was enhanced by a preceding period of food deprivation.
