I can only give you my experience - and I know other people on the forum have come up with different views.
I have a micro-brewery and our spent grain has been going for some time past to a local small-holder as pig feed - I don't know what proportion of their diet the spent grain constitutes, but he's had no problems.
We have kept pigs ourselves outside the brewery and have fed them almost exclusively on spent grain mixed with bits of waste beer and wort (unfermented beer). The 2 we have just sent to slaughter only had 4 bags of pig nuts between them over the 5 months we had them - the rest of their diet was grain beer and wort, plus what they got from clearing a half-acre enclosure. And they were happy, healthy and taste delicious.
Ours have been used to the diet from a young age - I don't know how they would react to a sudden change. Also we nearly always feed them the grain as a sloppy mix with beer or wort mixed in and a handful of nuts. I know other contributors have said when this question has been raised before that you should limit the %age of grain fed to a rate much lower than what we feed to ours - but as I say, I can only give you my experience.

I've got nothing against feeding any free feedstuffs, and also know of a brewer round by me who feeds his pigs all the left over stuff (good ale too), they do get nuts as well, and his pigs seem to do well off them. However one reason i give a limited % on these matters is that they (pigs) cant digest the grains as good as ruminants, so excrete a lot of the goodness (so if you had sheep etc be better to give it to them), also if we on here were to say go ahead and feed over 50% of the grains to them and they did, and the pigs died because of it who'd get the blame?
By only feeding 10% to begin with the owner can see whether or not the pigs like it and whether or not they get an ill effect from it, if they don't then you can increase if you so wish to..
