Here's my very limited experience FWIW.
I have had cow elk come into my baits, not with enough regularity to count on.
I rarely as in the proverbial once in a blue moon have mature bucks visit the bait during shooting hours.
I am baiting for two reasons; to attract mature bucks on camera for location and selection and to attract does who will hopefully go into estrus and make the nocturnal mature buck temporarily love struck and dumb enough to walk out in front of me during the day.
Bears and deer will both visit the bait. I almost always have a bear or two on cam, but the deer still come in. Bears will camp and even nap on the bait, that will temporarily keep the deer away.
Apples work great, but attract every animal in the forest. I have weirder pics of random animals when I use apple than any other bait. Ravens, bunnies, bears, deer and a coyote all in one day. Yes the raven flew off with an entire apple in its beak. The yote did not partake as far as I could tell.
I tried commercial attractant baits, but Alfalfa and corn seemed to work better. Only tried 3, so maybe they're just picky.
Certified weed free alfalfa is required on federal land, not sure if that applies on all public land?
Locate and area that has good sign first and then locate a spot where the wind, approach and light are in your favor to place the bait.
Still learning, so I appreciate information folks share.
