Keep your pig eating by syringe feeding. Dont squirt it too fast incase he or she inhales it into the lungs. Syringe feed water also, same rules applys.
Which antibiotic? Have you managed to get the first dose in?
I really must go to sleep. Take a look at the guide i linked above, which is by wiebke , i cant help you anymore I'm afraid.
Just a quicky. If you have the 1ml oral syringe, cut the tip off of it. The narrow part, else you will struggle sucking the food up. But if you have only the 1 syringe, make sure you can still use it for the antibiotic. Sorry, I'm rushing this post
