Effects of E+ Fescue

Symptoms of ergovaline poisoning in livestock are:

  1.  decreased milk production (as much as 45% reduction!)
  2. poor body condition
  3. general poor health
  4. decreased weight gain (stocker gains can be halved!)
  5. delayed hair coat shedding
  6. low conception rate
  7. low birth weight
  8. circulatory problems (ie: ear tips freezing, sloughing off of tail switch, even so far as to slough off hooves)
  9. lameness
  10. loss of appetite
  11. abortions
  12. poor circulation also leads to inability to dissipate body heat (especially troublesome in the heat and humidity of summer) (this is the main problem which leads to the above symptoms)

The cause is that the fungus is a vaso constricting substance called ergovaline.  A good explanation comes from Endophyte Service Laboratory, College of Agriculture Sciences
Oregon State University, Corvallis, Oregon 97331 USA.

The toxin ergovaline is a vaso-constrictor, it constricts the blood vessels and reduces blood circulation to the outer parts of the animal’s body. Animals that have consumed a toxic dose of ergovaline will have difficulty regulating body temperature. The constriction of blood flow also can cause “fescue foot”. Fescue foot is characterized by gangrene or tissue death in the legs, ears and tails.

Recent research done by Matt Booher, Crop and Soil Agent at Virginia Coopoerative Extension and John Benner indicates that despite our best efforts, endophyte infected fescue at all stages of growth causes some level of poisoning to livestock.

Seems mind boggling that we farmers and ranchers continue to allow this non-native plant to be grazed by our stock, doesn’t it!?  Tannachton Farm is on a mission to remove it.  It will be a fight since the grass is allelopathic and persistent!

Getting Ready

One would think you could just pull in and start with tillage for planting crops as part of my fescue elimination project.  Alas, that isn’t true in my case.  Since i had subdivided the 120 acres into 6 paddocks with 2 wire hi-tensile electric wire, all this had to be wound up and stowed for replacement after 4 years as per my plan.  Old fence posts and wired had to be pulled up and stacked for burning when time allows and entrance gateway had to be widened.

There’s been a 16 foot gate here for longer than i’ve been alive, although this is a new gate i had installed about 5 years ago.  But, 16 foot opening is far too narrow to pull in comfortably with big equipment, although you’d be amazed at what a skilled driver can get through!

So, this is the new look – set two new corner posts and hung two 16 foot gates.  Very professionally done by Jim Fitzgerald.

HUGE thank you and shout out to North Central Missouri Electric Coop for quickly removing, not only the lines from the transformer to the meter pole, but also my farm lines from the meter pole to windmill pump. About an 1/4 of a mile’s worth. While i did the ground work of chaining the pole to the front end loading, Dallas pulled the posts. Afterward, i dragged them to a burn pile with my Gator.

The electric company removed the wires from two tall poles which were on my property.  Our little tractor had to shove a bit on the pole, then really hunker down to get these poles pulled up.  As you can see, they are buried quite deep.  Instead of burning these poles, they were cut to length and used as the corner posts for my new gateways!

Old fence left over from who knows when still across the pasture with wire buried and tangled.  What a mess but at last we prevailed.

Here are half the posts from that fence.  These will all burnt in a pile.  Would make good firewood if they weren’t full of staples and wires.  The corner posts were too heavy for me to lift into the bucket, so we just used the tractor to pull them ’round to the burn pile – it wasn’t far.

An old home built load out chute we drug up out of the middle of the pasture.

With most posts pulled up, Dallas is building me a low water crossing while I pull the remaining posts to burn pile and roll up another half a quarter mile of hi-tensile wire.  Weather is perfect for working but I’m about out of steam!

I bet you were wondering how I can roll up 12 gauge hi-tensile electric wire.  The key is this spinning jenny from Powerflex Fence.  Don’t do this without a spinning jenny  Notice the rolls of wire I stored nearby; ready to roll back out after the 4 year renovation.  All told, I rolled up a bit more than 2 miles of hi-tensile wire and pulled some 140 fiberglass posts.  Many were 1 inch and were easily pulled by hand.  I hauled them all home and have them stored on a pallet in the barn.

Here you can see the old hand strung electric line from way up at the barn down to the electrified pump.  It used to be run only with the windmill, but there is not enough reliable wind to make that very viable.  Anyway, those were the posts Dallas and I pulled up.

Dallas and I did this in a couple days of remarkable weather in November!

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.

A page scanned from “The Clifton Park System of Farming and Laying Down Land to Grass” by Robert Elliot.  Quoted here as seeing in a book already written as to the New Zealand species of tall fescue containing ergot.  (we now know that it is ergovaline produced by the fungus endophyte which is hosted by the fescue plant)

Fescue Toxicity

Boy, howdy, now there’s an exciting title and one to really pull in a reader eager to learn about such a thing.  Well, not, of course, but to cattle farmers and ranchers across a great portion of the United States, it’s a reality that sucks an estimated $1 billion out of our collective pockets EACH year!

in 1943 Kentucky 31 variety of fescue was commercially introduced and sold, it seemed at first a godsend to sod forming, persistence, deep rootedness (soil conservation), and production for cattle and other livestock producers.  In the late 1970’s, scientists at last identified that fescue hosts a fungus that can produce toxic compounds called ergovaline.  However, it is important to note, that reports of  toxic effects of grazing infected fescue have been around at least since the early 1900’s.  Why didn’t the light bulb go off that there is a problem that needs addressing BEFORE scattering it all over the US!?  The only answer that seems reasonable is that establishment of the grass is cheap and easy and the resultant health concerns in stock are a silent drain.

Whatever the case may be, I’m now on a mission to eradicate to a degree as much as possible toxic fescue from my pastures.  In so doing, cattle health and numbers should increase, calf gains and cow milking ability should increase as well as reproduction improvements.  Additionally, soil health and tilth should improve, thereby increasing its moisture capturing and holding capacity (resulting in less runoff and erosion).  Lastly, but certainly not least, ridding the pastures of tall fescue will greatly improve wildlife habitat – especially ground nesting species such as quail.

The fruits of this project will likely be for the next generation and i ask myself if it is really worth the expense and effort to make a bold move in such uncertain times of low cattle prices.  Time will tell, i guess.

I think I’ll put these entries in a separate category so my reports and progress can be easily accessed.  I’m no Pioneer Woman like Dee,  (ya gotta admire the outreach she has done with her whit and way with words),  but if you have an interest in organic, no chemical, minimal tillage farming, pasture renovation, cattle rearing for producing clean healthy food while improving (regenerating is the popular term) our environment, come alongside and join the conversation.  I will enjoy any questions.

Cheers!

This is a nice photo of my cows, but what you don’t see is that a good portion of what they are grazing is toxic endophyte infected fescue.  In other words, with every bite they are being poisoned.  It’s time to see if the dollars and cents to renovate make sense to change this condition.
