I'm cautiously optimistic. He started eating veggies on his own today. I had to feed him Critical Care every 4 hours for 2 days and had to inject saline under his skin (sub-cue) every 12 hours to stop him from getting dehydrated. He was eating almost nothing on his own for the last 2 days. I was up every 3 hours last night hand-feeding him because he was hardly pooping. He had to go on both Baytril and Bactrim at the same time because the Baytril alone wasn't enough. My new pig died because the 1st antibiotic he went on didn't work in time (despite the fact that I took him to the vet immediately) and by the time he got on a 2nd antibiotic, it was too late.
Sorry, bublegine, seems I've hijacked your thread. But this message is important for anyone getting new pigs:
Quarantine your new pigs, even if you think you don't need to.
Mites are not the only reason to quarantine a new pig. New pigs are under a lot of stress due to: change in diet, getting chilled during transportation, new environment. Pigs are very prone to getting URIs (pneumonia), especially when under stress. Pigs can also have un-detected medical problems such as heart-defects which can affect their ability to withstand an illness. Your new pig may get sick due to stress and can pass the illness onto your other pigs. My new pig got pneumonia, then gave it to my other (previously healthy) pig.
Also, when you get a new pig who has supposedly been treated for mites, don't assume your new pig doesn't have mites. Often it takes several treatments for mites to completely kill all the mites. It is very important to treat mites because mites can affect the pigs immune system. When my new pig died, I looked at him very closely and noticed his fur was overrun with mites, both adult and baby mites. My other pig caught the mites and now has to be treated.
