Weanling with diarrhea

My poor baby has had diarrhea for a week and a half and the vet can't find anything wrong yet. I heard that this is pretty normal for them to go through after they are weaned. She was weaned at four months and then she came home with me to a new place. I started her on safe choice feed and she was fine for a few weeks. Then I increased her feed and she got the diarrhea. There is nothing in her stool that the vet can find. We gave her half a wormer. Also I am giving her plain yogurt, kaopectate, pepto, and mineral oil twice a day. We are waiting for a bit before we try anything more drastic so she wont colic. It has improved, but Im curious if anyone has gone through this? How long will it last? I can tell she feels a little better and has been running around a bit. Thanks for any advice or success stories!

I am dealing with diarrhea with a older horse, I don't know about a weanling.I don't think I would give plain yogurt, kaopectate, pepto all at the same time.My vet had told me to use plain yogurt for 3 days and if no inprovement then stop giving it to him. If none of those are working after about 3-5 days I would call the vet.
Have you tryed to cut back on her feed and see if the diarrhea stops?

Dac 911 or DDA may be the way to go. The 911 has antibodies in it and the DDA has mycotoxin binder. Both are good probiotics.

I didn't think Safe Choice was for growing horses? If you are looking for a low or no grain feed, check out Triple Crown. I give my younguns either Triple Crown Senior or Ultium. Be sure to give at least 6 pounds daily of the Triple Crown per the label. My colt is on DDA, Calm-B, and Colt Grower. Once I move him to Fl he will go on 911 and switch to Ultium feed then back to DDA. Then in Nov I will put him on Breeder's Choice in prep for the breeding shed.

If she stressed during the weaning period she may have an ulcer. The 911 helps out with those.
I would cut out the mineral oil - it can loosen the stool in of itself.

Also I am giving her plain yogurt, kaopectate, pepto, and mineral oil twice a day.

Be careful with the mineral oil. That's what we always used as a laxative.

Safe Choice is a wonderful feed for all equines.

OP - what type of roughage is the weanling getting? Did that change at the same time she was weaned?

Thanks for all the advice. I will let my vet know that I want to reconsider the mineral oil. I will be talking to her again tomor to see what she wants me to do next. Ill ask about an ulcer possibility and the 911 or dda.
mls- she is getting a good quality coastal hay and I kept her on the same hay from the previous owner when she got the diarrhea. I had cut back her food in half, but now the vet wants me to start building it back up because she is looking a little ribby. Not too bad yet thankfully. Does anyone think this could be long term damage from being weaned at 4 months? I guess Ill start panicking if it doesnt get any better in a week. Her stool is I guess like a cow patty. It was runny all the time, so there is some improvement.

Once you get the diarrhea to stop she should bounce back development-wise.

Just feed her good quality feed and supplements like you normally would - don't try to "make up" for lost growth - provide plenty of turnout and exercise. Keep up with your worming program, give plenty of good hay and keep out fresh water and free choice salt.

I wean mine at 3 to 5 months depending on how well they are eating and how tired mom is of them. The majority of the time I see a development issue when they are long-term not getting enough nutrition (fed 1 scoop "Sweet Stuff" a day and coastal hay) or fed more than a hard working adult horse would need (2 scoops Ultium 3 times a day with free choice alfalfa).
