Mysterious Illness....Any ideas as to what it could be?!

We have a yearling standardbred filly. Staring last week she started to not finish all her feed. After examining the feed I realized it was just the oats she wasnt eating. I began mixing her feed better and things were fine. She's not usually very rowdy in her stall but she had been somewhat too quiet. She would just stand in the back and not move until turn out time. She would nit pick at her hay while she waited on occasion.

Well through out the pass two days this is what has happened:
-She will NOT finish all her feed, oats or anything else
-She is very very quiet still but not a "normal" quiet.
-She will eat her hay but basically one stalk at a time.
-She has a temperature of 102 degrees celsius.
-She also has a less noise coming from her gut.

About two weeks ago we dewormed our horses and we are well aware colic can strike after deworming. We were also thinking there is a possibility of West Nile (she was vaccinated).

If nothing seems to be better by tomorrow afternoon we will be calling a vet out. Just in the mean time are these symptoms familiar to anything you know about? Do you have any ideas of what is wrong with her?

I would have a vet out there ASAP

I also vote for the vet ASAP.

Be sure to ask him about ulcers.

Yepper. It is common for very young horses to get ulcers --- just from the birthing process up thru the weaning process.

Ulcers will cause horses to react differently, but going off her feed and not being "up to snuff" is one of the symptoms.

That is how my Arab acted four summers ago with his ulcer. He was 18 then and his was from the extreme heat & humidity coupled with TWO tooth infections. He had lost one molar on his own but needed the other one pulled.

I attribute his tooth issues to him being starved so badly when I rescued him years ago. It took him a year to recouperate and whenever there's a long period like that, who knows what will happen later down the road.

Anyway, I would call the vet and ask about the ulcer possibility :)

A call to the vet would definitely be a good idea.

What did you deworm with last?

Get a vet -- she may be in shock from something. Until you know what it is, you can't help her.
