There is no protein in corn oil, only fat. I doubt this would make a good attractant for deer. First there is not that much oil in corn, so it is probably does not contribute much to the attractiveness of corn. Also, I am not sure it would be very palatable to a ruminant. We are different than deer (of course), but can you imagine sitting down to a nice warm glass of corn oil?! <img src=icon_smile_tongue.gif border=0 align=middle>
