Fifteen progeny of two Polled Hereford sires were fed endophyte-infected tall fescue seed (E+) to investigate variability in susceptibility to fescue toxicosis. One sire, bred in Missouri, was reputed to produce calves that were resistant to fescue toxicosis. The Control sire, from Virginia, had unknown merit for susceptibility. There were two phases in which E+ was included in the diet (2 and ...

The currently recommended treatment for metronidazole toxicosis is drug discontinuation and supportive therapy. Reported recovery times are 1-2 weeks. The records of 21 dogs with metronidazole toxicosis were retrospectively analyzed to determine whether diazepam improved recovery. The dosage and duration of metronidazole therapy and the response and recovery times of 13 dogs treated with diazep...

Antihistamines are H1-receptor antagonists widely used in human and veterinary medicine to provide symptomatic relief of allergic signs caused by histamine release, including pruritus and anaphylactic reactions. Antihistamines are also commonly used as sedatives and antiemetics. 1 Antihistamines can be divided into first and second-generation (also called nonsedating) agents (Table 1). First-ge...

For tall fescue in the southeastern USA, long term persistence, competitiveness, yield, and summer survival are directly related to the presence of a fungal endophyte (Neotyphodium coenophialum; formerly called Acremonium coenophialum) living in the fescue plant. However, cattle grazing forage from the predominant USA tall fescue cultivars infected with their naturally occurring endophyte strai...

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...
