I know many people like to put food out for wildlife. My role is to share information with you so that you can become more knowledgeable about our native species. So this comes from NYSDEC. Let me add - it is illegal to feed deer in NYS.
Deer Diet
Although it may appear to be a simple act, feeding deer in the winter can be an especially difficult endeavor to do correctly. Deer are ruminants, similar to cows, and have complex digestive processes. They have multi-chambered stomachs and rely upon micro-organisms, instead of digestive juices to break down food so that nutrients can be absorbed. The types and concentrations of the micro-organisms are specific for various food types. What might work well to digest woody browse will not digest supplemental foods such as corn or other grains. If there are any changes in a deer's diet, it can take up to several weeks for the culture of the micro-organisms to adjust to the newly introduced food. Deer may readily consume new foods, but in fact receive little nutrition for an extended period of time.
During the winter period, deer digestive systems are normally set up to digest their regular diet of woody browse, twig tips, and buds. Food provided to them by browse cutting provides nourishment with no delay in receiving energy from the food. As a result, the cutting of hardwood, and in some cases softwood browse has been a long standing recommendation for those concerned about deer survival in the winter. In light of the new concerns for the introduction and spread of CWD, browse cutting is even more acceptable because the risks normally associated with artificial foods and high deer concentrations are greatly reduced. In addition to providing immediate nutrition, the long term benefits of browse cutting can also result in improvement of the overall deer winter habitat.
