马匹营养/矿物质
< 马匹营养
由 Jo-Anne Murray 编写的马匹营养
• 用于各种功能
– Growth – Co‐factors to enzymes – Involved in transport of energy
• 矿物质消化
– Majority absorbed in Small Intestine – Majority of Phosphorus absorbed in Large Intestine
• 两类矿物质
– Macro‐minerals – Micro minerals/Trace minerals
• 大量矿物质
– Required in relatively large quantities (g/day)
• 微量矿物质
– Needed in very small quantities (mg/day)
• 数量和矿物质比例都很重要（例如，ca:p 比例）
• 两类矿物质
| 大量矿物质：每天需要 g | 微量矿物质：每天需要 mg |
|---|---|
| 钙 (Ca) 20 | 钴 (Co) 0.5 |
| 磷 (P) 14 | 铜 (Cu) 100.0 |
| 钠 (Na) 10.0 | 钼 (Mo) |
| 钾 (K) 25.0 | 锌 (Zn) 400.0 |
| 镁 (Mg) 7.50 | 锰 (Mn) 400.0 |
| 硫 (S) 15.0 | 铁 (Fe) 400.0 |
| 氯 (Cl) 40.0 | 铬 (Cr) |
| 氟 (F) | |
| 碘 (I) 3.5 | |
| 硒 (Se) 1.00 |
NRC 建议体重 500 公斤的成年马在维持状态下每天摄入上述矿物质量；请记住，需求量会根据马匹的年龄、体重和用途而有所不同。 http://nrc88.nas.edu/nrh/
