The best for animal husbandry and land stewardship is often a balanced decision. These past two years in north-central/northwest Missouri and a bit of southwest Iowa makes grazing management decisions tough to call. Two years of unusually dry and hot summers each followed by severe cold and long winters has left our pastures and pasture management in tatters. The following article printed in Midwest Marketer magazine is from Iowa State University Extension beef specialists Erika Lundy and Denise Schwab offers some ideas for consideration. We live in toxic endophyte fescue country, so it is not a best practice to encourage its growth with the addition of any type of applied nitrogen. Legumes planted can mitigate the effects by replacing the poisonous grass, but must be managed with proper grazing.
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.
