Like much in the world of whitetails, the timing of when they shed their racks can vary widely among individual bucks and herds. However, the key to antler casting is declining testosterone levels following the rut. In the South, it is not uncommon to see antlered bucks as late as February or March. In other regions, particularly in northern states that have traditionally been heavily harvested, some bucks may begin the process as early as mid-December. Injuries, poor habitat conditions, and heavy rut-related stress can also result in declines in testosterone and cause bucks to drop their antlers earlier. In contrast, a lengthy rut can prolong their interest in does, and they will retain their antlers for an extended period. One thing that we have noticed is that individual bucks tend to be remarkably consistent in the timing of this phenomenon from year to year; we have some deer in our research facility that will cast antlers almost during the same week.
