Piglet diarrhea

Hello all. I have three piglets (9 weeks old), that I picked up from a very reputable farm nearby one week ago. They all had mild diarrhea for a few days, but now one is having severe diarrhea. It just constantly drips from his rear end, it is pale green in color. The piglets are all acting great. They are eating, drinking, and playing as normal. They were on pasture grass, hay, and a pellet mix at their old home, and are now on barley grass, clover, and a medicated pig starter diet. The feed store employee recommended the medicated diet because of the major problems with diarrhea in pigs last year. This is our third year raising pigs and we have never used medicated feed before. I just did some research on the medication (Carbadox) and I am really upset that I have been feeding this. I has been banned from most countries and the FDA has just recommended that this be removed from animal feed due to it being a carcinogen. I will return the bags to the feed store, but what should I do about the diarrhea? I have given yogurt for the last couple of days, but there has been no improvement. Should I just be more patient? As I said, they are all acting normal (other than nasty diarrhea in one). Sorry this is so long. Thank you for any help/advice, I really appreciate any feedback.

What kind of yogurt have you been giving them? If it has been pasteurized then all the good gut bacteria are dead. I've found that you need a good active culture for the best results.

It is cultured, and contains live bacteria. I know you can give Kaopectate, but this piglet is really shy and will not let me near him. They were not handled at previous home. I guess I can try to sneak it into some applesauce or something.
Thank you for responding!!

I would take them off the medicated feed, they were not used to it and it is most likely the problem.
increase the pasture time and you should see the diarrhea stop.

If they had diarrhea when you bought them, then you might need to give them a medication but I would get them on a diet close to what they were eating prior to being bought.

I am taking them off the medicated feed today. They do eat a lot of grass now, but I will increase. Thank you!

Glad to be of help. We accidently gave our hogs diarrhea once by feeding them to many tomatoes (we get "dead" produce from our grocery store occasionally).
The cure was to simply get them back to their pasture diet and now we only give tomatoes and other "juicy" fruits and veg. as treats.
It took our hogs only two days to get over the diarrhea.

Good News!! I got home from work today around lunch time and the diarrhea is gone. I had picked up their new food (un-medicated) on the way home, so it wasn't due to that. I guess it was probable time and yogurt.
They were very active this afternoon, I guess they were feeling a little down after all. It's all a learning experience I suppose.
Thanks everyone!

Yes, it takes a little time to adjust to new animals, even if you already own the same type and breed, new stock can educate you on their individuality.

I finally got our farrowing house finished up, our first litter is due any day now.
