Locoweed Embryotoxicity in Rats
Clinical Toxicology, 1980In an effort to develop a laboratory animal assay for locoweed (Astragalus lentiginosus and Astragalus wootoni) teratogenicity, different amounts of the plant were administered either in feed pellets or by gavage to rats. In preliminary experiments with A.

Locoweeds, which are a common name for poisonous species of the genera Astragalus and Oxytropis, are toxic leguminous plants through a symbiotic association with the fungal endophyte Alternaria section Undifilum. The fungus produces an indolizidine alkaloid, swainsonine, which causes a toxicosis of grazing animals, named locoism.

Effects of Locoweed Toxin on Rats
American Journal of Veterinary Research, 1976SUMMARY Rats fed pellets containing locoweed developed typical microscopic lesions of locoweed poisoning. Rats fed a water extract of locoweed or urine from sheep given locoweed also developed microscopic lesions. This indicated that the locoweed toxin is water soluble and is excreted in the urine.

Locoweeds cause significant livestock poisoning and economic loss in the western United States. The toxicity of Embellisia sp. fungi isolated from locoweed was compared with locoweed toxicity using the rat as a model. Rats were fed diets containing locoweed, fungus and alfalfa, or alfalfa.

Physiopathologic Changes in Locoweed Poisoning of Livestock
American Journal of Veterinary Research, 1970SUMMARY A locoweed (Astragalus and Oxytropis spp.) feeding experiment was conducted in 3 phases. In phase 1, 16 sheep were allotted to 4 groups of 4 sheep each; 3 groups were fed Astragalus lentiginosus, Astragalus pubentissimus, or Oxytropis sericea for 56 days, and the other group (control) was not fed locoweed.

Herbicide Control of Locoweeds: A Review
Weed Technology, 1988Locoweed poisoning of livestock is the most widespread poisonous plant problem in the western United States. This paper presents a historical review of control methods to reduce locoweed plant density. Hand grubbing, the most common method of control before phenoxy herbicides, was practical in small pastures considering the number of livestock saved ...
