Why Do Bucks Shed Their Antlers Early in Some Years?

Causes of Early Shedding

In Manitoba, trophy bucks often face harsh winters that can lead to early antler shedding. Temperatures below -20°C (-4°F) can cause significant stress on a buck’s body, leading to early antler loss. Additionally, poor habitat quality can also contribute to early shedding. For example, a buck that has limited access to quality forage or mineral-rich areas may not have the necessary nutrients to maintain its antlers.

Impact on Trophy Bucks

Early antler shedding can significantly impact a buck’s overall score when it comes to trophy hunting. In Manitoba, the antler scoring system is based on the total score of a buck’s antlers, with larger antlers receiving higher scores. A buck that sheds its antlers early may be significantly penalized in the scoring system, reducing its overall score. For example, if a buck has a score of 170 inches but sheds 10 inches of its antlers, its final score would be 160 inches.

Management Strategies

To mitigate the impact of early antler shedding, hunters and wildlife managers can focus on improving habitat quality and providing access to quality forage and mineral-rich areas. This can be achieved through the creation of food plots, habitat restoration, and the use of mineral licks. In addition, hunters can also use antler scoring systems that take into account the age and condition of the buck’s antlers, rather than just the total score. By taking a more holistic approach to trophy hunting, hunters can help to ensure that only the most deserving bucks are recognized as trophies.
