Providing supplemental feed to deer in the winter is controversial and illegal in some states, but other states encourage and even help fund it. Here’s a look at some of the pros and cons of winter feeding.

The Minnesota Department of Natural Resources has often been opposed to recreational deer feeding. With the increased risk of chronic wasting disease (CWD) and other disease transmissions, there have been discussions about banning it. The winter of 2014 was very difficult for the deer of northern Minnesota. Deep snow and cold temperatures created conditions in which predators had a field day with stressed deer. In many cases ,wolves moved into certain areas and slaughtered far more deer than they could ever eat. Deep snow made finding food extremely difficult and many deer were near starvation by February and March.

Despite their history of opposition to the practice, the Minnesota DNR mobilized volunteers across the northern half of the state to distribute corn to stressed deer herds.

Near my home there was a 20-acre cornfield that did not get harvested before the snow came. There were 60 to 70 deer feeding in that cornfield every night. I had a discussion with a DNR officer about recreational deer feeding about that time. He felt strongly that recreational deer feeding concentrated the deer into areas where they could more likely transmit diseases. My response was this: “There are 70 deer feeding in this cornfield; they are nibbling on the same branches, eating fecal matter, and chewing on the same corncobs. Wouldn’t it be better to have those deer spread out into a dozen smaller recreational feeding sites at the homes of the adjacent landowners rather than have them all bunched up in one place? Wouldn’t that cause a reduction in potential transmission of diseases rather than an increase?” Neither one of us really have a definitive answer to that question.

These are just a couple examples of the controversy that surrounds recreational feeding of deer. Let’s take a look at some of the pros and cons.

Acclimation to humans

Opponents of deer feeding feel that providing handouts for deer can make them more vulnerable to negative human influences. In some cases this may be true, and there are specific instances in which deer feeding in the wrong areas has caused significant increases in roadkills. Deer feeding during hunting season can concentrate deer into areas where they are more vulnerable to hunters. But ask anyone who has hunted for deer over bait in states where baiting is legal and they will tell you that putting deer in a position where it’s easier to shoot them is a lot easier said than done.

Deer quickly learn when they are being hunted and will go nocturnal. Many states allow baiting of deer but very few mature bucks are killed atop bait piles. The human intrusion associated with putting the bait in place is simply more than a mature buck will tolerate. Even younger deer and does quickly learn that feeding under the cover of darkness is their best survival strategy.

One significant issue with feeding deer is the consistency. One of the worst things that can be done is to provide a food source that the deer become dependent on, and then stop feeding for a long period or quit altogether. Either of these can put the deer at significant risk. If deer are relying on you for a daily food source, do not let them down.

Concentrated for predation

Human predators are not the only threats deer face. Deep snow can cause deer to bunch up around available food. When snow makes it difficult for deer to move around, predators can move in and make short work of an entire herd. I have personally seen this in northern Minnesota, where a pack of wolves decimated a herd of more than 40 deer in one week.

Wolves are controversial enough but when things like this happen, the anger rises quickly. Contrary to what wolf lovers would like you to believe, wolves do not kill just what they need to survive and no more. Put yourself in a wolf’s shoes (paws) for a moment and think of it this way: you know where there’s a lot of deer, so you go kill one and eat your fill. The next day you’re hungry again, so you go back and you have the option of gnawing on a hunk of frozen meat or, with very little effort, grabbing a hot meal. Which option sounds the best to you? That’s why wolves can wipe out so many deer in such a short time.

Other predators also capitalize on vulnerable deer. Coyotes, mountain lions, feral dogs, and even bobcats and eagles have been known to feast on the easy pickings. Keep these predators in mind when you choose your deer feeding location. It’s best to utilize several smaller feeding sites rather than one large one.

This commercial deer feed not only contains the carbohydrates that deer need in the form of corn, but it also contains proteins and alfalfa pellets which help balance their diet.

Digestive issues

High-carbohydrate foods are needed to get deer through the winter because they produce quick energy and body heat. But radical changes to a deer’s diet can be harmful and in some cases fatal. Introducing a source of corn to very hungry deer when there is very little other food available can make it very difficult for the deer to digest the corn. When deer are feeding on woody browse, their stomachs are adapted to digest that type of food. They do not have the ability to change quickly in a sudden introduction of large quantity of high carbohydrate food can cause acidosis which can make them sick and in extreme cases can kill them.

For this reason it’s best to introduce alternate food supplies well before winter hits so the deer’s digestive system have plenty of time to adapt. When using corn to help starving deer, it’s best to introduce small amounts of corn in multiple areas. Or better yet, introduce a mixture of feed with a mixture of carbohydrates and protein. Some companies make deer feed that includes other grains and proteins in addition to corn.

The real bottom line is that a deer’s stomach will tell it what it needs to survive. We must be careful that we do not make radical changes to their diets or put them in positions in which they are more vulnerable than they would be if we did not interfere. Recreational deer feeding can provide entertainment for wildlife lovers and a benefit to individual deer and improvement of deer populations if it’s done in a responsible way.

    Up here in Eddington Maine we have fed our local herd for 10 years, all stock 16 from Blue Sea Feedl, hay and cracked corn, we started with 8 to 9 Deer ten years ago and in 2014 we had a total count of 32 Deer which consisted of around four individual groups, same does have been coming back sense they where fawns, we have produced 250lb. to 350lb. bucks as is evidenced on our game camera, every October / November the Big Bucks come in for a day or two and run all the does off for breeding, the does are gone for about two to three weeks before they start showing up again except for this year, a land owner a mile away is harvesting his wood lot so I have investigated where all are does, yearling, fawns and Bucks went ! and sure enough there in the cuttings eating downed tree brows rather than eating the feed we put out which shows that if natural feed is available they choose that first but when food is in short supply such as is normal here with our deep snow and sub zero temps they will come and eat our feed as a matter of survival, as I am a hunter, in 20 years I’ve never cut coyote track within a mile of our home stead and believe me I have traveled miles of Deer trails to see what predators may be in the area, Maine Sportsmen HATE coyotes so upon any sign we bait and kill them, Oh by the way Deer don’t shit where they eat but go into the woods bout 25 yards or so and there’s plenty of Deer poop, our Pug eats Deer poop like frozen chocolate chips snacks, Nasty Dog now go brush your teeth ! I feel that if you have 1,000.00 to 1,200.00 that you can invest (if your area requires intervention) in ensuring good herd numbers and healthy Deer go for it Oh by the way I don’t hunt any of the Deer in our area I travel 10 miles east and hunt in Amherst which has produced a beautiful 10 pointer and 250lb black bear that adorn my game wall down stairs.
    Enjoy and post Your input.

    Feed the deer in the winter? To what or whom should we feed them?

    Seriously, a friend of mine in NJ has a next door neighbor who insists on putting out corn for ‘the poor animals’ in the winter. Consequently my friend has a steady supply of venison all winter after the cars have finished tenderizing the deer. The auto body shop, tow truck companies and paramedics have a steady stream of work.

    Everybody wins, except for the deer.
