Tine Development: Are Certain Genetics More Prone to Dropping?

Understanding Tine Development Genetics

Research suggests that genetics play a significant role in determining the likelihood of dropped tines in whitetail deer. A study found that 15% of deer with a dominant allele for tine length (T) are more likely to exhibit dropped tines, while only 2% of deer with a recessive allele (t) show this trait. This suggests that deer with the dominant allele are more prone to dropped tines.

Factors Contributing to Dropped Tines

In addition to genetics, various environmental and nutritional factors can contribute to dropped tines. For instance, deer that experience nutritional stress during the growing season may be more likely to drop tines due to a lack of essential nutrients. Similarly, deer that are exposed to high levels of competition for food and resources may also be more prone to dropping tines. A study found that deer with an average daily gain of 0.5 pounds or less during the growing season were 3.5 times more likely to drop tines compared to deer with an average gain of 1.5 pounds or more.

Identifying Deer Prone to Dropped Tines

Hunters and wildlife managers can identify deer prone to dropped tines by observing the structure and development of their antlers. Deers with a history of dropping tines may exhibit signs such as shorter tines, irregular branching, or an asymmetrical rack. By monitoring deer populations and tracking the development of their antlers, hunters and managers can gain a better understanding of the factors contributing to dropped tines and develop strategies to mitigate this issue.
