Information from Our Wildlife Experts
Animal experts at the Purina Animal Nutrition Center share their knowledge about wildlife.
I’ve heard that deer cannot tolerate more than 16 percent dietary protein, and that high-protein diets are wasteful or even toxic. Is this true?
No. Research in South Texas has shown that wild deer diets at certain times of the year can be more than 25 percent protein. Many forbs highly utilized by deer are more than 30 percent protein. Obviously, the wild deer are unharmed by consuming these high-protein plants. Indeed, excellent antler growth years were those with superb spring forage conditions. The resulting antler growth suggests that not only were the deer not harmed by their high-protein diet, they actually utilized the protein to grow bigger antlers, indicating that higher protein is necessary for a buck to achieve his genetic potential for antler growth.
