stomach issues?

I just moved my horses to a new barn from being out on pasture for a couple of months this summer. I noticed yesterday that when my mare pooped it has this slimy film covering over it and there were some goopy slime pieces in it. My original thought was worms but that just didn't seem right. She has been wormed regularly although is 2 months behind at the moment (I am just about to worm her now) since I have had a lot going on in my life and just had to put the horses aside these last 3 months. I am a responsible horse owner, and they were still getting care but no one was really inspecting the poop while they were out. I checked her poop in the stall today and it all looked normal.. Could it be something shedding out in the colon or a bit of an infection?

Also she is fat from being out in the pasture, but I am noticing that she is a bit ribby too. Again, a typical sign of worms, but that just doesn't seem right... She acts completely normal, no signs of colic, discomfort, or anything. I've attached a video I took of her today where you can kind of see her stomach. It just seems odd to me, but maybe I am over reacting. The other 2 horses she's been with have been completely fine and I have not noticed anything too unusual. One of them has had some runny poops since we moved him, but not bad and he gets nervous in a new environment.

Any advice would be appreciated. I'm on a tight budget and don't want to call the vet unless absolutely necessary...

I think some Pro-Biotics would do her some good..It will get her stomach working like new..It helps the stomach digest and keep the good nutrients from what she eats,..The stomach gets out of whack sometimes..And this stuff balances everything again..
This is where I buy my Pro-Biotics, I pay a fortune to have it shipped to me here in NB Canada, but the product is worth it...

I'd say to go ahead and worm her. If you're still concerned about the possibilty of worms afterward, you could do a mail-order fecal test instead of calling the vet out.

Moving is always a little stressful on horses, so I wouldn't be too concerned about a little bit of diarrhea as long as her poop looks normal now.

I would not worm her before a fecal test, why send more chemicals into her stoamch before you make sure she has worms....we all have our way of caring for our horses, I don't want to step on anyone's toes, but that's what I would do if I was in the same situation..Keep us posted.

How 'good' is the roughage she has been eating? A belly with ribs can indicate that although she is eating, she is not digesting = the mucous on the manure. If the hay is too coarse or stemmy or the grass dry, it can be plain roughage and no real nutritional value. The belly is from undigested hay but they also keep eating because their body feels the need for nutrients. A ration balancer might be in order.

Thanks all for the responses - they are definitely helpful! The roughage/pasture she was on was irrigated with quite a few different types of grasses. She was also getting a daily vitamin so I would think she was getting enough vitamins, but maybe not. I agree about the worming, the barn does all of theirs at the same time and are due for the beginning of September so I think I'll just wait so she doesn't get too many. The poop looked normal again today so I really don't think it is worms.

I think I will try the pro-biotics. Is probios a good one?

Has long has the stuff is " Live"..like the enzymes, bacteria, etc.. should be living..Make sure the product is not out of date..Pro Biotics don't usually survive more than 6 months after they made..I looked at the web site for Probios and they look fine..I have never used them, so I can't recommened them, but all the good stuff seems to be in it..I usually use the product from Earthsong Ranch, but last spring I tried Omega Alpha Biotic8, I was pleased with the product..My horse gets 2 months worth of Pro Biotics every spring, Its a part of his care routine....It can't hurt anything, but it sure can fix the tummy..Alot pf people I know give Pro biotics right after their horses have been on antibiotics, or have been dewormed..

Baby Lee, thanks for all your suggestions. I'm going to pick some Probios up at the feed store tomorrow!
