Best food in winter for pigs outside?

[combat squirrel]

Hi all I have 4 pigs outside in a very insulated/technically advanced hutch (i heavily modified a 'rose cottage pets at home' hutch - the entire back, sides and front have the latest available foam insulation trapped between 2 marine wood layers with a removable layer for the front, the floor on the 'bedroom' area has a heatpad that gets to 20c and kicks in at 5c - and all of the hutch is underneath a heavy duty hutch cover)

So as you can see, they should be fine

However, it IS still going to be fairly cold out, so I want to know whats a good diet in addition to the usual to 'fatten them up' for the coming winter cold ?

You could add some porridge oats to the diet on cold days, but they should be OK on a normal good diet with a few more pellets.
