Dangers of Grazing E+ Fescue Short

Study Shows Dangers of Short Grazing Toxic-Fescue Pastures by Cattle Herds

Research results published November 30, 2017 by Sarah Kenyon, PhD, University of Missouri once again illustrate how grazing the non-native, invasive toxic-endophyte (E+) fescue plant causes health problems in cattle and other livestock, including horses.  Other studies show the effects on the soil microbial populations and wildlife.  E+ Fescue is pervasive, persistent, and poisonous.

Short grazing of E+ fescue in the last fall/early winter before a killing frost has been used by us and others to manage the spring growth of the plant by shortening the root system which slows spring growth, allowing more desirable grasses and legumes to get a foot hold.  This is effective, but a relentless endeavor since it must be done every fall/winter to control the fescue and quite simply, there is no way to manage ALL the fescue at once everywhere on the farm.

I’m thankful for professors and agricultural leaders bucking the status quo and revealing this long-known information to a modern generation and offering solutions to not only mitigate the health issues associated with the toxin, but also ideas on eradicating it.  Time will tell if changes will work – it’s expensive to renovate and manage pastures and fields – – and farming and ranching does not lend itself to wide margins of profits to plough back into improvements.

E+ Fescue History

Not even going to bore you with a long history of a specific grass – I don’t even want to read about it.  Given the little dab of history i’ve uncovered that was already known about toxic endophyte infested tall fescue, E+ tall fescue being sold as a wonder grass in the early 1940’s must surely have been one of the most duplicitous marketing schemes ever played on the American farmer.  And we fell hook, line, and sinker for it.  Now planted and still being planted on at least 35-40 million acres across the midwest and southwest United States.

Tall fescue has good attributes – it surely does.  You can overgraze it, trample it, burn it, freeze it, mow it, dilute it (with other forages), plough it and it will come back year after year even stronger yet.  But, as i have shared earlier, that persistence is purchased with losses in the health of livestock and decimated wildlife forage and habitat.

As evidenced by the following documents, I suspect we could keep digging backwards in time and discover that at least one cultivar of Tall Fescue has been wreaking havoc for many, many years.
