Brazle, F.2010-12-082010-12-082010-12-08http://hdl.handle.net/2097/6838Thiabendazole (TBZ®) wormer pellets were added to either a mineral or grain mix in two experiments with steers grazing 50% endophyte fungus-infected, tall fescue pastures. Research from other stations has suggested that TBZ® partially overcomes the toxicity of endophyte fungus. In our experiments, steers received .2 g of TBZ® per 100 lb body weight per day, but daily gain was not improved during the grazing period.BeefThiabendazoleStockersFescueEndophyteConference paper
