:roll: I use both, I keep salt and mineral blocks out year round.
There is nothing wrong with feeding corn, but it has very little nuterational value for the deer. If you want to see an improvement in the fawn production, better quality doe and improvement in the rack size, then go to Purina Anthler Max. I mix it with corn, one bag of corn, one bag of Anthler max until the feeder is full. My feeders is a 55 gal drum with removable top, they have a timer feeder usually set for 8-10 seconds twice a day. The 55 gal drum holds about 250 lbs of feed and usually last about six weeks.
As with any program, you will not see an improvement overnight, but after two-three years you should see larger racks and an overall improvement in the deer herd.
