Why do some genetics lead to more frequent dropped tines?

Antler Structure and Genetics

Deer with a high degree of branching in their antlers are more susceptible to dropped tines. This is because the more complex the antler structure, the greater the stress on individual tines, which can lead to breakage and dropped tines. A study of whitetail deer found that deer with 3-4 points on their main beam were more likely to have dropped tines than those with 2 points or fewer. This suggests that a more complex antler structure can increase the likelihood of dropped tines.

Tine Angle and Antler Mass

The angle at which tines grow from the main beam also plays a role in the likelihood of dropped tines. Tines that grow at a more acute angle are more susceptible to breakage than those that grow at a more obtuse angle. Deer with lighter antler mass may also be more prone to dropped tines, as their antlers are less robust and more susceptible to damage. A study of deer antlers found that those with a higher antler mass index (AMI) were less likely to have dropped tines than those with a lower AMI. The AMI is a measure of antler mass relative to body size.

Selecting Deer for Trophy Potential

For hunters interested in selecting deer with good trophy potential, it’s essential to consider the genetics of the deer being hunted. By identifying deer with antlers that are more robust and less prone to dropped tines, hunters can increase their chances of harvesting a high-quality trophy. This may involve selecting deer with a more obtuse tine angle, higher antler mass index, and fewer points on their main beam. By understanding the genetics of deer antlers, hunters can make more informed decisions when selecting deer to hunt.
