Whilst John Seymour ('Self Sufficiency' author) lists cooked potatoes under food, he also mentions keeping pigs on a field of potatoes or allowing them to forage after main harvest so it must be OK. I'm sure Ive seen commercial pigs after-grazing a potato field. I bet the cooked potato thing is a calorific thing (maximising absorbtion and producing a warmth hit - warmth seems to be a big factor in food --> meat conversion). Great Forum, thanks! Our first 4 Saddle backs are arriving on Saturday yeay.
