cottonseed meal for winter protien supplement

[paus]

Has there ever been any research on using cotton seed meal for protein supplement for bees?  The analysis is in the ballpark but does it work?

I have talked some beekeepers about cottonseed meal and they had never thought about this.  One beek asked me why I thought about using CSM as bee feed.  When I was much younger I had cattle and fed CSM mixed with minerals and salt.  The bees flocked to that cattle supplement.  I kept looking on the internet and found an article from Jan 1917 in the Minnesota Bee culture periodical That is very interesting, some cattlemen did not like the bees from a neighbor Beek and they poisoned the bees.  There is some very interesting and enlightening articles of how we "usta" do it.
