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 late 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.
