I had a problem with greasy pig last year - mum rejected her wee boy when he came back from castration at 3 weeks old & he went down-hill very quickly.
You will definately know if it is greasy pig because of the smell - it's bl**dy awful
- & lots of tar-like pus with craking skin, very noticable under the belly. He became very hunched-up & shivered a lot, due to the splitting & thickening of his skin.
Wee Harry did make it
- I kept him in a dog crate in the house for over a month, constantly changing his bedding of towels & a hot water bottle, plus heat lamp for the 1st week. I was feeding him every 3 hours - baby milk & mashed banana/apple with pestled weaner feed. Antibiotic injections every day for 10 days & a twice daily bath of anti-bacterial dog shampoo (from the vet, but not licienced for pigs). He's never really grown much, but now keeps one of my stud boars company over the summer
Our vet told us it's not a very good survival rate for greasy pig, due to damage to internal organs & yes, it's more common in gilt litters (something to do with a lack of antibodies in 1st time mums). It's a horrible infection to deal with, but Harry is an example of how they can pull through - I hope yours make it ok
