20:20 I'm puzzled. Cool season grasses as of little food value? Presumably you mean '....for deer', since these grasses are preferred by farmers for grazing for cattle. And yet, both cattle & deer are ruminants. Is there digestive difference, or does the difference in value of habitat lie only in the value of cover to deer?
Deer eat little to no grass at all. I’m amazed at how many hunters I meet planting rye grass in their plots. They had no idea deer don’t eat it. They will eat cereal rye though. Some tall grasses like switchgrass and Egyptian wheat are great for screening food plots as deer don’t like eating out in the open.
