2007 Aging Study

We received teeth from 74 pronghorn taken during the 2007 season, all of which were sent on to the Armendaris Ranch and Marston’s Laboratory for aging. The results are listed below. Previous studies have shown that pronghorn horn size depends on the age of the animal with most trophies being between the ages of four and six. Winter temperatures, and the precipitation received and the forage conditions present are also important. Moreover, bucks born during a good year tend to have large horns throughout their life.
