Do you know that Fescue Toxicosis is a very common but under talked about problem with cattle?
Since we bought the farm in 2021, I have always wondered why our cows were caked in mud but other farms had these beautiful cattle. It wasn’t until the KCA convention this year that I finally learned the reason behind that. Fescue Toxicosis.
Fescue Toxicosis is caused by cattle consuming tall fescue infected with the endophyte fungus Neotyphodium coenophialum. So basically, even tho the fescue is a great source of fiber and energy, it can also be deadly if it becomes infected with this fungus. If cut and rolled into hay, the fungus can stay in there for 2 year, which means even in the winter months, they continue to consume it.
‼️ Now, let me add, It Is not toxic to cosume the meat of a cow that has this.‼️
It can cause symptoms like heat stress, weight loss, rough coat, reduced grazing, “summer slump”, low pregnancy rates, and even death. The more they eat, the worse they get. It leaves farmers confused as to why they eat constantly but still look poor and dont gain weight.
Because it is a fungus that causes the issues, there’s so way to really “treat” it. All you can do is have better pasture management by diluting your pasture with legumes and other grasses, prevent seed heads from forming, and using herbicides.
Below, you can see our cattle right before they were rotated to a different part of the pasture. You can see how a few cows have a nice, slick appearance to their coat and all the others have a thick, nasty mud coat. Now that we have identified the issue, we have worked since beginning of spring to help our cattle get better. Connor sections our pastures into smaller areas, which allows them to graze but prevent overgrazing. When they have options, they are less likely to eat the seed heads of tall fescue. Mineral is offered to them 24/7 and we monitor the progress every day. We have noticed our mama cows gaining weight each day, their coats are getting more slick, and they seem overall happier.
If you own cattle, whether it’s 1 or 100, and you have fescue, this is something that should be on your radar. It’s not known by a lot of people but it is an issue that is very common. You can do something about it which will leave you with happier and fatter cows.
I share this non glamorous picture of our cows because I have learned that sometimes, other farmers can by judgy when it comes to cattle. We’re real and honest here and want to help educate others on things we’ve learned along the way. ❤️
