oxytropis glabra/tremor

In the last five years in western Mongolia, a neurological disorder and resultant economic loss have developed in goats, sheep, cattle and horses: association of the disease with ingestion of Oxytropis glabra, a toxic plant, was suggested. Affected goats showed neurological signs, including ataxia,

Serum alpha-mannosidase activity and swainsonine concentration were determined in 4 cattle and 15 sheep (3 groups of 5 each) that were administered ground locoweed (Oxytropis sericea or Astragalus lentiginosus) containing swainsonine at dosages of approximately 0.8 mg/kg of body weight/d (cows, 30

Locoweed poisoning has been reported in wildlife, but it is unknown whether mule deer (Odocoileius hemionus) are susceptible. In areas that are heavily infested with locoweed, deer and elk (Cervus elaphus nelsoni) have developed a spongiform encephalopathy, chronic wasting disease (CWD). Although

By a series of experiments, we identified a new member of the locoweed family, Oxytropis serioopetala, that produces swainsonine, a phytotoxin harmful to livestock. In order to evaluate the toxicity of Oxytropis serioopetala, its extract was administered to ten rabbits by gavage at a dose of 1.5
