new adoption - adult pig

Question
I just adopted a potbelly from the SPCA. I was told she was 80 lbs, but I have lifted her - she is much heavier I assure you. They also told me she is pregnant - they had a younger male pig house with her a few weeks and they "witnessed the act", I was told. I have read all sorts of things about pigs, but they all seem to start with babies, but I am starting with an adult pig - I have no idea how old she may be. I found her online and called to inquire. I guess the person I called gave my number to the shelter - they called and offered her to me. The ad I initially read is at this link -

I am not sure of it's acuracy. The shelter had to catch her - apparently it was such an ordeal, it made their local  news, so they tell me (I never saw it - I traveled 80 miles to get her). Oddly, I was charged nothing for her - just come and get her, I was told.
She is very friendly, but not cooperative at all. Am I going to be able to leash train her and/or litter train her? Do I just follow the same guidelines for young pigs? How much should I feed her daily. She was housed outside at the shelter. I have converted a nice shed for her - lots of straw - is the enough for cold Ohio nights, or should I try to transition her indoors now? And if she is outside, does she need a light to see when she is in the dark ( I have read about their poor vision.) She will be going to the vet in about 2 weeks, but I just want to know what I can do now.

Also, a friend told me they can eat rabbit feed/pellets? I have purchased pig feed for her - just curious if that is really true - as a supplement. What can she NOT eat - like treats - I understand not to overfeed her and stick to the pig feed, but what exactly do I offer her in addition to the feed? (and how much?)

I'm sure I will have more questions in the next few weeks, but if you could help me in getting her established and making sure she is happy I'd be glad to hear it. :)

Thanks!

Hello,
I will try to address the issues you have in order.
From the picture I saw she looks to be in the 120 lb range.
She looks to be in good weight for her size and that is good.
PBP's come into heat every 21 days.  Just because she was covered by the boar doesn't mean she is positively pregnant although you certainly don't want to rule it out completely.
It is always harder to adopt an older pig who is set in her ways than a young piglet that you can teach as you go.
It is extremely difficult to teach a large pig to walk on a leash because they are so strong.
I would recommend the Infinity Plus Harness/Leash as it will fit any size pig and will really get her attention with out harming her. You can find it on the product page at royaldandie.com.  I have used this leash and it works great on all animals.
As far as feeding goes it depends on what you are feeding her.  If you will write to my at patty012001@yahoo.com I will give you more information on that subject.
In the winter I would use a well secured heat lamp as well as straw.
Do not feed Rabbit pellets.  They are much too high in protein for your pig.
Try to keep the protein level no lower than 10%
and no higher that 14% with 12% protein being just right.
Makes sure she gets an good Vitamin/Mineral supplement which you can also find at royaldandie.com.
Treats can be apples,grapes,raisins,carrots etc.
No Chocolate, caffeine or salt.
Hope this helps,
Good luck, Patty
