Actually, I hear quite frequently about people eating the greens. And that's one thing that I also do often - when I see a whitetail eating something I will snip a piece and try it for myself - not necessarily for the taste, but to see how fast it breaks down.
This is Dr. Grant Wood's "Five chew test"
Whitetails are slaves to their gut, and a whitetail with an empty stomach is one that is on the move, seeking something to fill that empty rumen. Research has shown that foods with higher lignin content, or more woody, tough foods like twigs and stems, takes longer to digest. Deer with a diet high in lignin move less and are probably seen less by hunters. Many popular foodplot forages like clovers and brassicas are low in lignin content and digest more quickly - meaning more feeding times and increased deer movement.
One easy way for you to test the toughness and digestibility of the browse your deer are consuming is to do a “chew test.” I like to pick a sample of my food-plot crops, chew it between my back molars (as a deer would), and after five chomps spit it out to see the results. If I chew a juicy leaf of brassica, for instance, it should be well ground up and ready to be swallowed after only five chews. Try this with a stalk of, say, ryegrass - five chews later that stem is going to look the same as it did when you put it in your mouth. Use my “five-chews test” to see just how digestible your crops are for deer.
