Quick Answer
Deer age affects their preference for minerals, with younger deer showing a higher preference for calcium and phosphorus-rich minerals essential for growth and development.
Mineral Lick Preferences by Age
Research shows that fawns (0-6 months) prefer mineral supplements with higher calcium content (12-18%) to support bone growth and development. As deer mature, they tend to shift their preference to salt blocks with lower calcium content (8-12%). By 1-2 years, deer prefer mineral licks with balanced calcium and phosphorus levels, while older deer (3-5 years) tend to focus on salt and water intake.
Mineral Supplementation for Deer
When supplementing minerals for deer, it’s essential to consider the age and sex of the deer. Fawns and does require higher calcium and phosphorus levels, while bucks can tolerate lower levels. A general rule of thumb is to provide mineral licks with the following compositions:
- Fawns: 12-18% calcium, 8-12% phosphorus
- Does: 10-14% calcium, 6-10% phosphorus
- Bucks: 8-12% calcium, 4-8% phosphorus It’s also crucial to provide multiple sources of minerals, including salt blocks, mineral licks, and loose minerals, to ensure adequate intake.
Legal Considerations for Mineral Supplements
When supplementing minerals for deer, it’s essential to check local regulations regarding mineral supplementation and the use of salt blocks. In many areas, the use of salt blocks is prohibited due to concerns about water pollution. Before supplementing minerals, ensure that you understand the laws and regulations in your area. Additionally, consider the environmental impact of mineral supplements and take steps to minimize waste and prevent pollution.
