- ... An 8-year-old, crossbred beef cow was referred to the Indiana Animal Disease Diagnostic Laboratory at Purdue University for a complete necropsy in October 2009. The cow was the sixth to die in a 7-day period. Affected cows were reportedly stumbling and became weak, excitable, and recumbent. Histologically, myonecrosis was severe in the skeletal muscles and mild in the heart and tongue. According t ...

- ... White snakeroot (Ageratina altissima) is a sporadically toxic plant that causes trembles in livestock and milk sickness in humans that drink tainted milk. The putative toxin in white snakeroot is tremetone and possibly other benzofuran ketones, even though it has not been demonstrated in vivo. Toxic white snakeroot was dosed to goats, and they developed clinical signs of poisoning, exercise intole ...

- ... Tremetone and possibly other benzofuran ketones are believed to be the toxic compounds in white snakeroot. However, disease has not been reproduced with purified toxins and the concentrations of the benzofuran ketones in white snakeroot populations that cause toxicosis have not been documented. The objectives of this study were to compare the toxicity of seven plant populations, better characteriz ...
