Journal ArticleDOI
White snakeroot poisoning in goats: Variations in toxicity with different plant chemotypes
T.Z. Davis,Bryan L. Stegelmeier,Stephen T. Lee,Mark G. Collett,Benedict T. Green,James A. Pfister,Tim J. Evans,Daniel Grum,S. Buck +8 more
TL;DR: The incidence and severity of poisoning was not correlated with total doses of tremetone or total benzofuran ketone concentrations suggesting they may not be closely involved in producing toxicity and the possible involvement of an unidentified toxin.
Journal ArticleDOI
Two Delphinium ramosum chemotypes, their biogeographical distribution and potential toxicity
Daniel Cook,Dale R. Gardner,Stephen T. Lee,Clinton A. Stonecipher,James A. Pfister,Kevin D. Welch,Benedict T. Green +6 more
TL;DR: This study profiles the alkaloid composition of D. ramosum throughout its geographical distribution using both field and herbarium specimens and demonstrates that botanical classification alone is not an adequate indicator of relative risk of toxicity.
Journal ArticleDOI
Selected Common Poisonous Plants of the United States’ Rangelands
TL;DR: Selected Common Poisonous Plants of the United States Rangelands as mentioned in this paper, a list of common poisonous plants of the U.S. rangelands, is presented in Table 1.
Journal ArticleDOI
The serum concentrations of lupine alkaloids in orally-dosed Holstein cattle.
Benedict T. Green,Stephen T. Lee,Kevin D. Welch,Dale R. Gardner,Bryan L. Stegelmeier,T. Zane Davis +5 more
TL;DR: The serum elimination of anagyrine in Holstein steers was faster than those reported for beef breeds, suggesting that Holsteins may be less susceptible to lupine-induced crooked calf disease.
Journal ArticleDOI
Alkaloid Profiling as an Approach to Differentiate Lupinus garfieldensis, Lupinus sabinianus and Lupinus sericeus.
Daniel Cook,Stephen T. Lee,James A. Pfister,Clint A. Stonecipher,Kevin D. Welch,Benedict T. Green,Kip E. Panter +6 more
TL;DR: The alkaloid profiles of Lupinus sabinianus, L. garfieldensis and L. sericeus can be used as a tool to discriminate these species from each other and from L. sulphureus as long as one considers locality of the collection in the case of L. sabinIANus.
