Tissue swainsonine clearance in sheep chronically poisoned with locoweed (Oxytropis sericea).
Locoweed poisoning is seen throughout the world and annually costs the livestock industry millions of dollars. Swainsonine inhibits lysosomal alpha-mannosidase and Golgi mannosidase II. Poisoned animals are lethargic, anorexic, emaciated, and have neurologic signs that range from subtle apprehension to seizures. Swainsonine is water-soluble, rapidly absorbed, and likely to be widely distributed...
متن کاملLocoweed (Oxytropis sericea)-induced lesions in mule deer (Odocoileius hemionus).
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 these are distinct diseases, no good comparisons are available. The purpose of this study was to in...
متن کاملConditioning taste aversions to locoweed (Oxytropis sericea) in horses.
Locoweed (Oxytropis sericea) is a serious poisoning problem for horses grazing on infested rangelands in the western United States. Our objectives were to determine 1) whether lithium chloride or apomorphine would condition aversions to palatable foods, and at what doses, and 2) whether horses could be averted to fresh locoweed in a pen and grazing situation. Apomorphine was not an acceptable a...
متن کاملLack of Maternal Influence on Lamb Consumption of Locoweed (Oxytropis sericea)1,2
Locoweeds ( Oxytropis and Astragalus spp.) are toxic plants found on many rangelands. Preferences for locoweed are learned; livestock often initially reject the plant, but learn to eat locoweed after continued exposure. Maternal influences are important in shaping diet selection in young animals. We studied the influence of ewe consumption of locoweed on lamb selection of the plant. Twenty-four...
متن کاملFeed preferences and habituation of sheep poisoned by locoweed.
Livestock addiction to locoweed is commonly cited as a clinical sign of locoweed poisoning. However, there have been no physiological or pathological explanations for the reported addiction. Four hypotheses were tested to evaluate locoweed's (Astragalus lentiginosus) addictive nature: 1) animals become psychologically addicted to locoweed; 2) animals have an innate preference for locoweed; 3) a...
