Feeding Deer

See the Latest News and Research Below. Also see food plots


Supplemental feeding of wild deer can improve survival and increase the population, but careless feeding can kill deer, transmit disease, or create management problems. Do not use corn or other fermentable carbohydrates as a primary emergency deer food. Deer are routinely killed this way by people trying to help. Examples below. Deer are browsers and have adapted to eating a wide variety of food sources, but their efficient stomachs require time to adapt to a new food source. A hungry deer that has not eaten corn recently can die within a day if it comes across a large pile of corn that it devours [bloat and acidosis].


There are over 10,000 deer farms in the U.S. where deer are fed products formulated for deer such as Monster Meal Feeder Pellets and Purina Antler Advantage, with a protein content of about 16 to 20 percent, which are suitable as an emergency feed. Other similar pelletized products that can be used are available for rabbits, goats, or horses with main ingredients of alfalfa hay, soybean meal, distillers dried grains, rice bran, and corn (less than 25 percent) with protein of at least 12 percent. Goat (chow) feed is widely available. Oats are a preferred supplement. The state of Maine has previously used a mix of oats and barley, but has recently increased the use of alfalfa hay. Some deer may take time to adapt to these unfamiliar foods.


Deer enjoy a wide variety of fruits and vegetables such as apples, grapes, small plums, cherries, pears, pumpkin, carrots, snap peas, tomatoes, squash, almonds, watermelon, figs, turnips, honey locust, watermelon, persimmons, and sunflower seeds. Setting out individual servings is a good way to reduce disease transmission. As with people, individual tastes vary. Acorns and other mast are an important food source.


Good trees include pears, apples, crab apples, persimmons, aspen, white oaks and red oaks, ash, aspen, maple, popular, willow, white cedar, yellow birch, red mulberry, and chestnut. Also soybeans, dogwood, pokeweed, aster, ragweed, goldenrod, sumac, and honeysuckle.


Feeding deer may increase the transmission of chronic wasting disease and other diseases. Check the map to see if you are in a chronic wasting disease area. Reducing food pile density can reduce transmission probability. The Mississippi DWFP recommends using an above ground covered feeder. An example. Leaving food on the ground significantly increases risk of toxins and other harmful agents. Poop should be removed. Food should be distributed, otherwise dominate deer may prevent younger and smaller deer from eating. Feeding deer is illegal in some jurisdictions. Planting food plots is an effective, safe, and legal way to support local deer populations.

Corn is often used as a food supplement, but is low in protein and nutritional value. It may result in acidosis if introduced too quickly, killing the deer, so should be used sparingly as an energy supplement such as for does trying to feed new fawns. Corn is high in starch so should not be used as a primary food source. Arkansas Game and Fish warns that in addition to poor nutritional content, "commercially sold 'deer corn' does not meet the requirements of corn sold for livestock." Use fresh grains from a reputable source to avoid poisining deer with alfatoxins.


C.O.B. (corn, oats, and barley) is readily available, but has protein of only about 8 percent and is high in corn content so must be introduced slowly. Goat chow usually has properties similar to deer chow, about 16 percent protein, alfalfa is a primary ingredient. Second cut or later alfalfa is commonly used, but deer also need time to adapt to this food source. Deer can starve with a stomach full of alfalfa they cannot digest.


The Michigan DNR permitted supplemental feeding during the severe winter of 2013-14 and provided these guidelines: "Feed can consist only of grains, second cut alfalfa and clover, and pelletized food materials containing no animal protein. The feed must be scattered on the ground at a depth not to exceed three inches. If individuals choose to feed corn, the DNR recommends it be mixed as a minor component, 25 percent or less of the recipe, which should help protect deer from dying by acidosis..."


For the supplemental feeding of 2017 the DNR added this advice: "Although deer make use of apples, potatoes, sugar beets, carrots, and many other foods during summer and fall, these provide little benefit for deer during winter conditions..." The Wisconsin DNR advises that for winter feeding, if formulated deer products are not available then "rabbit, goat or horse pellets which contain at least 12% protein can be used...

Deer have been routinely fed over thousands of years. Ancient peoples managed deer and their habitat as an important natural resource. Government agencies have opened feed sites to entice deer away from farm fields and other locations.
