• livestock
  • Allowable limits for cereal ergot alkaloids in livestock feeds are being re-examined, and the objective of this study was to compare nutrient digestibility, growth performance and carcass characteristics of ram lambs fed a range of alkaloid concentrations, including the maximum currently allowed in Canada (2 to 3 ppm).

  • dietary
  • Eight ram lambs (30.0 ± 3.1 kg) were used to examine the impacts of dietary treatments on nutrient digestibility and alkaloid recovery from feces. (mdpi.com)
  • Concentrations of dietary alkaloids evaluated did not affect nutrient digestibility or N metabolism. (mdpi.com)
  • Due to different concentrations of alkaloids affecting growth and carcass characteristics in the present study, determining allowable limits for total dietary alkaloids will require a better understanding of impacts of alkaloid profiles and interactions among individual alkaloids. (mdpi.com)

  • They provide in fact several benefits to their host, including the production of different herbivore-deterring alkaloids, increased stress resistance, and growth promotion. (wikipedia.org)
  • Containing more than 4100 known different compounds, it is one of the largest classes of alkaloids. (wikipedia.org)
  • secondary
  • The chemical basis of insect resistance in endophyte-plant defense mutualisms has been most extensively studied in the perennial ryegrass and three major classes of secondary metabolites are found: indole diterpenes, ergot alkaloids and peramine. (wikipedia.org)
  • main
  • One hundred patients suffering from sustained arterial hypertension were studied over a period of two years during which time the action of parenterally administered hydrogenated ergot alkaloids (Hydergine) constituted the main drug therapy. (ahajournals.org)
  • Production
  • It is isolated from ergot or fermentation broth and it serves as starting material for the production of bromocriptine. (wikipedia.org)
  • growth
  • Feeding 2447 ppb total alkaloids negatively impacted growth, while feeding 1402 ppb did not harm growth performance, but reduced carcass dressing percentage. (mdpi.com)
  • mass
  • Because ergots have similar density to grains, traditional threshing techniques generally failed to remove them, and outbreaks of ergot typically led to mass poisonings. (mdpi.com)
  • plants
  • The first indole alkaloid, strychnine, was isolated by Pierre Joseph Pelletier and Joseph Bienaimé Caventou in 1818 from the plants of the Strychnos genus. (wikipedia.org)

  • Of interest was a group of 22 patients presenting evidence of early central vascular derangement in whom these alkaloids seemed to accomplish their best therapeutic action and possibly aborted what may have been a sustained cerebral accident. (ahajournals.org)
