I add about 1/2 pound of ADM Minerals per 100#. Usually up it to 1# when they start fawning and growing antlers. Soy oil and molasses will help it stick, but a lot ends up in fines and gets feed to the wild deer when I clean out their troughs instead of being injested. The textured feeds I've seen look like good mixes but they are too expensive for me to feed. I found that adding oats and sunflowers attracted birds and have cut them out. I am currently feeding about 10% corn, 5% Calf Manna and rest ADM 18%. I only add the calf manna because it smells good and has more minerals. I increased corn a while back and a lot had loose stool so I cut it back down immediately, but I know there are some very experienced farmers feeding 50% corn rations.
