Rat tail - losing switch

Postby angus9259 » Tue Jun 20, 2017 7:18 am

Always this time of year I lose some tail switches. I had the vet take a look - he's baffled. The skin at the end of the tail gets scales and scabs and the hair falls off - just the end of tail. Google suggests it might be a certain kind of lice. Any thoughts?

Tried posting a picture but, once again, my "add a picture" button at the bottom of my post is missing....

Well, I am egotistical I've been told, but I don't feed fescue.

Is it possible that some other feed you are using has a fungus that might be releasing a vasoconstrictor?

It sounds like some sort of lice. IMO.

This is what things point to but the vet couldn't find any lice and the hair doesn't grow back.

They are just on pasture when it happens. Doesn't mean something in pasture isn't doing it.

What about mites? He can see lice but would need magnification to see mites.

I was thinking Fescue toxicity as well, ergotism. But, if they are not eating any Fescue grasses, I'm stumped.

Has the vet taken any tissue samples and sent to a pathologist?

Are you sure you don't have native fescue in your fields?

Good question. Gonna look into that. Certainly don't have fields of it, but it may be out there.

Seems like it must be something in your fields if it happens each year. It is possible to be mites, but, I would think the switch would grow back??? You might check with Michigan Univ Livestock Specialist. Sometimes there are things going on in the state that vets are not aware of.

If its fescue they'd be losing part of their tail, not just the hair....right
