White-tailed Deer Protein Needs

Deer Management – Deer Protein Requirements

A deer manager should consider deer nutrition on a seasonal basis. Energy and protein needs change based on the season, physical activity, and the age of individual animals. Changes in the nutritional requirements of deer that occur with gestation, lactation, breeding, and antler growth should be coordinated with seasonal changes in nutrient availability from forage plants. Nutritional requirements of deer are generally separated into five categories, which are protein, energy, minerals, vitamins, and water. Research on white-tailed deer has primarily focused on protein, energy, and minerals (phosphorus and calcium). These requirements are most often the ones that limit growth, reproduction, and antler development.

Protein is very important for body growth in deer, especially for fawns and yearlings. Inadequate protein intake in a given year will also reduce antler development in bucks. In fact, a period of inadequate nutrition (low protein) for buck fawns may adversely influence antler development for several succeeding years. A deer must obtain at least a 6-7% crude protein diet to maintain rumen function, but a protein diet in the 14-16% range is required for successful growth, antler development, and reproduction.
