I have the option to get wet brewer's grain fresh from a local brewery to feed my broiler birds and feeder pigs. Should I do it? The brewer says it's only heirloom oats & barley. I imagine it would spoil quickly. Is this beneficial at all? I am currently feeding whey,apples,and swine mix grain that is 15% protein. I've heard of it being good for ruminants, but I don't know about pigs and poultry. Any advice/experience? Thanks!
