gilt injury, gross pic included

About a week ago my 8-9 month old gilt turned up with a very swollen, ripped, and ozing vagina. We seperated her and called the vet, who gave the phone advise it was fisrt mating and to put a topical anti-biotic on. He said it could also be an abortion. She acted fine until yesterday when I noticed she is having trouble getting up and down.
Which seems related to her CONTINUING PREGNANCY. I'm pretty sure she's preggo because I could feel the pglets moving. Here is a pick from last night before reapplying the blucoat. The swelling has gone down considerably. Any thoughts?

I wish I had the knowledge to help. Can you update?

Around 3am last night see delivered 8 live and one half-size stillborn piglet. One was cold when I got there about 3:30 and subsequently died. She seems to be doing well.

Thanks for the resource--I will have to read it!
