Fescue Toxicosis is currently one of the most costly diseases that beef producers in the eastern United States are facing. The syndrome is caused by a fungal endophyte that infects tall fescue, the predominant forage in Tennessee. Fescue Toxicosis in cattle can cause fescue foot, rough, thick hair coat in the summer, decreased feed intake, and decreased serum prolactin levels, which drastically...

Heat stress is a major problem in transporting stocker calves with symptoms of fescue toxicosis. Removing calves from tall fescue pastures and offering diets devoid of endophyte-infected tall fescue could reduce the severity of toxicosis and precondition calves for transport to the feedlot. In the present experiment, a pasture phase was used to condition yearling steers to grazing tall fescue a...

Hepatotoxic plants are important cause of economical losses in farm animals in Brazil. This report concerns an outbreak of acute hepatic toxicosis, in which seven goats died after consumption of green leaves from a felled Trema micrantha tree. Two of these animals were necropsied and several tissues were processed for histological examination. Main histological finding was observed in the liver...

The present experiments examined the conditions under which rats rapidly learn to avoid ingesting visually distinctive food objects associated with toxicosis. It was found that the presence of a novel taste associated with a visually distinctive food object faciliated acquisition of visual-cue-toxicosis associations. Further experiments failed to support either higher order conditioning or sens...

In the order Coleoptera, cantharidin is produced by two families, Meloidae (true blister beetles) and Oedemeridae (false blister beetles). Cantharidin is of veterinary and medical importance, since it is super toxic to animals and humans. The present work was conducted aiming to review the cantharidin investigation and cantharidin toxicosis to animals including pathology, symptomatology, preven...
