Carole would love to hear about the sunflower seeds. I would imagine that the pig's coats will shine. (We used to give the horses oil to make their coats shine). Its interesting how the price of feed has encouraged a diversity of foodstuffs. I read an article that in UK they are even "considering" reintroducing the use of pig swill.
I feel that properly used it is a useful food, which will also help to reduce the amount of landfill. I'd be interested in anyone else's views. (Hope that doesnt sound pretentious).
