Deer-crop interactions in maize: diet and agronomy

Livestock animals consume corn kernels, stalks (especially young and tender ones), and whole plants. After harvesting, spilled grain becomes accessible feed. Although deer are not particularly selective about cultivars and eat both field and sweet corn, this cereal does not replace a complete diet. Corn serves as a source of carbohydrates and energy, but it is low in the proteins, vitamins, and minerals necessary for health and growth. A complete diet includes grasses, grain legumes, and other feed.

Excessive consumption of corn harms livestock animals: it leads to nutrient deficiencies, rumen acidosis, and other health problems, while long-term feeding causes dependency and vulnerability to disease. Artificial top dressing with corn also attracts raccoons, squirrels, opossums, wild turkeys, and predators like coyotes, which disrupts the ecological balance. Depending on the region and regulations, the use of corn as hunting bait may be restricted or prohibited.

For crop protection and to reduce damage, farmers use fencing (the most effective method), repellents, sonic deterrents, and scarecrows. When top dressing is necessary, specialists recommend using alternative products with a more balanced nutrient composition.
