The short answer would be year-round. However, a deer’s protein requirements are higher when does have developing fawns and when bucks are re-growing antlers. Although deer can typically obtain all they need by natural browse, the use of a good, high quality forage supplement can help does develop healthier fawns. Late winter through spring can be a time of greatest requirements for pregnant does. Bucks begin re-growth in their antlers soon after antler drop so this is the time to offer a balanced feed providing protein, minerals and vitamins. Both bucks and does require sufficient nutrition throughout the summer in order to support milk production and antler growth. However, under normal conditions nature provides an abundance of natural, high quality browse that provide deer with their nutritional requirements.
