This study estimates the caloric value of red deer milk as assessed relating bomb calorimetry data with the main milk nutrients. The study also examines milk energy estimates and lactation variables to compare Iberian red deer hinds (Cervus elaphus hispanicus) and the most studied Scottish red deer (C. e. scoticus). The final model predicted energy value (Ecal) in kcal/g of fresh milk from fat (F) and protein (P) content of milk, but not lactose: Ecal = 0.345 + 8.332 F + 5.403 P. Energy content per gram of milk increased with lactation stage but there was no difference between subspecies. However, subspecies differed in the daily and total energy production. Although milk energy values appeared to differ with estimates following the most used model developed from livestock, milk energy of deer estimated by both methods showed a very high correlation with each other, and both yielded also similar correlation coefficients with the remaining lactation variables. Calf gains showed a greater correlation with mean protein content and total protein yield, than with total energy yield or other milk nutrients. Milk protein appears to be more relevant to calf growth than gross energy yield.
本研究通过将量热法数据与主要乳营养成分相关联，估算了马鹿奶的热量值。该研究还考察了乳能量估算和泌乳变量，以比较伊比利亚马鹿母鹿（Cervus elaphus hispanicus）和研究最多的苏格兰马鹿（C. e. scoticus）。最终模型根据乳中脂肪（F）和蛋白质（P）含量（而非乳糖含量）预测了鲜乳的能量值（Ecal，单位为kcal/g）：Ecal = 0.345 + 8.332F + 5.40P。每克乳的能量含量随泌乳阶段增加，但亚种间无差异。然而，亚种在每日和总能量产生方面存在差异。尽管根据从家畜中开发的最常用模型估算，乳能量值似乎有所不同，但两种方法估算的鹿乳能量彼此之间具有非常高的相关性，并且与其余泌乳变量的相关系数也相似。与总能量产量或其他乳营养成分相比，犊鹿增重与平均蛋白质含量和总蛋白质产量的相关性更大。乳蛋白似乎比总能量产量与犊鹿生长更相关。
