My understanding was that animal protein and molasses based feeds have a shorter shelf life IE rancid. Any truth to that?
I don't like ANY feed that is old, vegetarian or otherwise. This is again why I prefer my local feed mill as the feed is ground fresh every week. Date stamped on the feed tag. I've seen bagged, trucked in feed in some "rural lifestyle" stores be as much as 6 months old.
While somewhat inconvenient perhaps, I do not purchase a 4 month supply of feed. I'd rather return every month for fresh feed.
