Abstract

Milk composition in two species of insectivorous bats (Myotis lucifugus and Eptesicus fuscus) was determined. No significant differences in fat, lactose, protein, or energy content were evident during the lactation period for M. lucifugus. The percentage of fat, lactose, and protein averaged 13.5, 3.3, 7.4, respectively, for M. lucifugus, and 16.4, 2.5, 6.2, respectively, for E. fuscus. Energy content of milk averaged 7.32 kJ/g for M. lucifugus and 8.37 kJ/g for E. fuscus. The percentage of lactose in milk from M. lucifugus was significantly greater than in E. fuscus, but there were no significant interspecific differences in percentages of fat or protein. The two species also differed significantly in content of five out of nine fatty acids.

摘要

测定了两种食虫蝙蝠（北美鼠耳蝠和棕蝠）的乳汁成分。在北美鼠耳蝠的哺乳期，脂肪、乳糖、蛋白质或能量含量没有明显差异。北美鼠耳蝠的脂肪、乳糖和蛋白质百分比平均分别为13.5%、3.3%、7.4%，棕蝠分别为16.4%、2.5%、6.2%。北美鼠耳蝠乳汁的能量含量平均为7.32千焦/克，棕蝠为8.37千焦/克。北美鼠耳蝠乳汁中的乳糖百分比显著高于棕蝠，但脂肪或蛋白质百分比没有显著的种间差异。这两个物种在九种脂肪酸中的五种含量上也有显著差异。
