Can Genetics Really Change The Antler Growth In Iowa Deer?

Understanding the Role of Genetics in Antler Growth

Research has shown that deer genetics play a crucial role in determining antler size and growth. In Iowa, where whitetail deer are abundant, genetics can influence everything from antler size to shape and symmetry. One way to gauge the impact of genetics is by looking at the antler scores of a deer’s parents and grandparents. For example, if a buck’s sire has an average antler score of 120, and his dam has an average antler score of 110, the buck’s own antler score is likely to fall within a certain range.

Selective Breeding for Larger Antlers

Selective breeding is a strategy used by deer farmers and hunters to increase the antler size of their deer. By choosing bucks with desirable antler characteristics and breeding them to does, hunters can increase the likelihood of producing offspring with larger antlers. For example, studies have shown that breeding a buck with an average antler score of 140 to a doe with an average antler score of 120 can produce offspring with an average antler score of 130. This represents a 10-15 point increase in antler score, which can be significant in Iowa’s whitetail deer population.

Measuring the Impact of Genetics on Antler Growth

To measure the impact of genetics on antler growth, deer hunters and farmers can use various techniques, including antler scoring and genetic testing. Antler scoring involves measuring the inside spread of a buck’s antlers, as well as the length and circumference of the main beams. Genetic testing, on the other hand, involves analyzing a deer’s DNA to identify genetic markers associated with desirable traits such as larger antlers. By combining antler scoring with genetic testing, hunters can gain a better understanding of the genetic factors influencing antler growth in their deer herd.
