Studies have shown environmental stress, health of deer, nutrition availability, age, and genetics are some of the determining factors relating to the size of deer and their antler growth. Bradigan's Wildlife Feeds has developed an ideal vitamin-mineral supplement that can be used to help control these variables by substantially increasing health, age, reproductive success rates and overall size of deer and their antlers. Bradigan's has never and will never use animal by-products in any of its feeds. The idea is to keep the deer healthy by giving it the correct amounts of vitamins and minerals. By doing this, the deer will have healthy bodies, healthy bones and strong antlers.
