What factors affect antler size in mature bucks?

Question

Accepted Answer

Genetics and Breeding Genetics have the most significant impact on antler size, with certain breeds such as the Boone and Crockett white-tailed deer being renowned for their exceptional antler growth. Research suggests that a buck’s ability to produce large antlers is heavily influenced by the genetics of its sire. In one study, it was found that a buck’s antler size is correlated with the antler size of its sire, with an average increase of 15-20% in antler size from sire to offspring. This highlights the importance of selecting bucks with superior antler genetics for breeding purposes.
Nutrition and Age While genetics play a critical role in antler growth, nutrition and age also have significant impacts. A buck’s diet must be adequate in nutrients such as protein, minerals, and vitamins to support antler growth. Research suggests that a buck requires around 12-15% protein in its diet to support maximum antler growth. Age is also a critical factor, with antler growth typically peaking between the ages of 5-7 years in white-tailed deer. Bucks that are fed a diet rich in nutrients and are adequately aged can produce exceptional antler growth.
Health and Management A buck’s health also plays a critical role in antler growth. Chronic health issues such as parasites, disease, and injury can significantly impact antler growth and development. Proper management practices such as regular vaccinations, parasite control, and adequate veterinary care can help mitigate these issues and support antler growth. In addition, adequate rest and stress management are critical for allowing bucks to reach their full antler growth potential.
