Sick pig(s)

I have 6 gilts, 7months old. They've been great and strong and happy. Fed milk from my cow and hog grower pellets.

5 days ago one vomited his undigested dinner when we went to feed at breakfast. We isolated him. He seemed to get a bit better but he's still lethargic and not eating much. Drinking fine. Doesn't seem to be hot but too energetic for me to get a proper temp.  Now two more are showing the same signs. They didn't even want milk.

We introduced cracked corn a week ago because they're going to slaughter in one week!
I've now removed the corn in case that's what has caused this. Any tips? How do I help these boys? I think I need to delay slaughter?

I'm sorry to hear about your pigs!

I'm not very familiar with hogs but just spitballing possibilities here. The cracked corn is a new introduction that you have mentioned. Could it possibly be tainted with mold? Anything funny with how it has been stored? I have heard of mycotoxins in improperly stored grains can cause issues with livestock.

You're thinking along the same lines as me -thats why I removed the corn.
But three guys seem totally fine. The sick three look...miserable. You can see it in their eyes.
Just to add a layer of stress I now see one walking with his head down and tilted. *Sigh*

What are the possibilities that it got hold of a poisonous weed?

Very unlikely.

I agree, unlikely on the poisonous weed front.  Vomiting pigs, yes that seems like the corn.   Check the corn source for sprays pesticides.  Whenever changing foods try soaking over night with probiotics ie short fermentation.  The hotter it gets the more pristine the drinking water needs to be.  Nothing floating, growing, tinting the water.  Cold, clear, and a lot, as well as a wallow for your pigs.  Hope this helps.

If you have to give them an antibiotic shot, then you would need to wait thirty days before butchering.
I had three ready to go to the butcher, when one got sick in a similar fashion. A shot fixed her right up.
Two days later, her buddys went to the butcher. For the next 28 days I was a part of the herd... all two of us.
She would see me up at the house, and come crashing through fences to get closer... A miserable time for both of us.

Called the vet. She also thinks it's likely from the corn. She said she has little she can give except for NSAIDs but to give them another day or two to try to improve.
This morning they won't eat and are drinking very little but they're walking around miserably.
Hopefully they pull through or I'll have a very expensive weekend-vet call to get her out here with some meloxicam.
Thanks for the help!

Update.
They were not eating and hardly drinking. I've been putting honey in their mouths so absorb some sugar and forcing 20ml at a time of some electrolyte in molasses.  Really no improvement. Still refused food and took maybe 5 sips of water all day.

I just went and decided to try straight dextrose syrup I have on hand. Holy moly it was a matter of minutes before they were all up and drinking and nibbling on food.

One vomited up undigested corn from a meal two days ago.  All signs are pointing to vomitoxin/corn mycotoxin.  Poor lads.  Hopefully they're on their way to recovery. I'll be out there every couple of hours to give a bit more dextrose and electrolytes. 🤞
