In the world of deer hunting, opinions and traditions often shape the choices hunters make in the field. One such tradition involves the decision to shoot or not to shoot a spike buck. While it may be tempting to take that shot, there are compelling reasons not to, rooted in a combination of age, nutrition, and genetics.

The Age Factor
Hunters, particularly those with more experience, understand the age factor as a crucial element in determining a buck's antler growth. Spikes are often the result of late-born fawns entering their first growing season. By the time hunting season arrives, these young bucks, at around 18 months of age, sport their first set of antlers. Late-born fawns prioritize body growth, and antlers become relatively unimportant when the focus is on skeletal development.
Scientific studies, such as one conducted by Keith McCaffery, a Wisconsin DNR deer researcher, reveal that spikes are predominantly found in yearlings. In forested northern Wisconsin, only 1.8% of 2-1/2-year-old deer displayed spikes, while the percentage dropped to 0.6% in farmland with better nutrition access. The age factor plays a significant role in the prevalence of spikes, and older bucks rarely exhibit this antler characteristic.
The Nutrition Factor
Nutrition intertwines with age to influence antler growth. Late-born fawns face a nutritional challenge, particularly during the late winter months. Without access to high-value nutrition, antler development suffers, increasing the likelihood of spike antlers. While supplemental feed and food plots are common practices, overwinter habitat becomes critical, especially in northern areas. The lack of quality nutrition contributes to a higher percentage of spikes among yearlings.
It's important to note that, despite efforts to provide supplemental feed and manage nutritional aspects, the struggle for late-born fawns persists. The nutritional factor emphasizes the complexity of deer management, extending beyond the reach of well-intentioned human interventions.
The Genetics Factor
Genetics, often considered the third factor, influences antler development but takes a back seat to age and nutrition. While some argue for a more significant genetic influence in southern deer, recent research suggests that genetics alone cannot override the impact of age and nutrition. Attempts to manage against spikes by implementing targeted shooting missions have proven futile.
Research shows that the mother contributes significantly to a buck's DNA, with up to 60% or more originating from the maternal side. Attempting to cull spikes prematurely disregards the complex genetic makeup and perpetuates the myth of "once a spike, always a spike." the genetics factor, while present, cannot be the sole determinant in managing deer herds effectively.
In conclusion, shooting a spike buck solely for the sake of filling a tag might bring temporary satisfaction, but understanding the age, nutrition, and genetics factors provides a broader perspective. Responsible deer management involves recognizing the intricate interplay of these elements and making informed decisions that contribute to the long-term health and sustainability of deer populations. So, before aiming at that spike buck, consider the bigger picture and the role each factor plays in the intricate dance of nature.
