I don't know how much grass you've got, but if the grazing is ok then all my adults get just 1lb a day (of Pot Bellie & Kune nuts), split into 2 feeds & the odd bit of veg/fruit/bread (depending on what's on the "cheapie stand" in Morrisons).
When the gilts/sows get to their last month of pregnancy I change them gradually over to Sow & Weaner & from 3 weeks to go up their feed slowly, with some extra fruit & veg (couple of carrots & an apple/pear/handful of grapes say) untill a fortnight before she'll be on 3 lbs of nuts a day (over 2 or 3 meals).
Once farrowed then I follow the same feedlines as karen, introducing a little feed to the piglets at 10 days old with tiny chopped fruit & carrots, keeping mum on the Sow & Weaner until the piglets are weaned. Once weaned the sows go back onto the Pot Bellie & Kune nuts & the piglets are kept on Sow & Weaner until they are 16 weeks.
Try not to worry too much over her, Kunes are great mums & have little, if any, complications. I wouldn't recommend changing her feed too suddenly, it'll give her the squits & won't be good for her condition at this stage.
Hope she "pops" soon - I've got one due on the 28th of this month (well by the calender - but pigs can't read

) we'll see who goes first
