Effects of feeding Kentucky 31 tall fescue seed infected with acremonium coenophialum to laboratory rats.
An endophytic fungus found in Kentucky 31 (KY-31) tall fescue has been associated with the "summer syndrome" (fescue toxicity) in grazing cattle. Four experiments were conducted to investigate the use of weanling rats as an animal model to study the fescue toxicity syndrome. When graded levels of fungus-infected (INF) or fungus-free (FF) KY-31 seed were fed, feed intake and growth rates were in...
متن کاملConsequences For Captive Zebra Finches of Consuming Tall Fescue Seeds Infected With the Endophytic Fungus Acremonium coenophialum
Tall fescue (Festuca rundinacea) plants can be infected with the endophytic fungus Acremonium coenophialum. This fungus, which grows subcutaneously in leaves, stems, and seeds, does not undergo sexual reproduction or sporulate, and cannot survive outside the plant (Clay 1988). The fungus is passed from one generation to the next through infected seed. A mutualistic relationship exists between t...
متن کاملTechnical note: sampling technique and drying method effects on chemical composition of tall fescue or fescue-ladino clover pasture samples.
Although esophageal extrusa is the most readily accepted representation of forage consumed by grazing ruminants, esophageal sampling is demanding from the standpoint of animal care and maintenance and extrusa processing. This experiment was conducted with a split-plot design to evaluate the effects of pasture type, pasture sampling technique and drying method on estimation of grazed forage comp...
متن کاملToxic endophyte-infected tall fescue and range grasses: historic perspectives.
A historic profile of endophyte-induced tall fescue toxicosis is presented. A chronology of events is presented, beginning with the importance of finding Balansia-infected grasses in a tall fescue pasture in north central Georgia. This initial finding was followed by the discovery that another related endophyte was present in tall fescue and other major forage grasses. This species of endophyte...
متن کاملInfection of Tall Fescue Cultivars with Non-toxic Endophytes
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...
