The weights of the brains of vitamin B12-deficient baby bats (Rousettus aegyptiacus, 4-20 day old) were slightly lower than those of B12-replete infant bats. Liver and kidney organ weights were similar in the two groups. Brain and liver B12 levels of B12-deficient baby bats were significantly lower than those of replete controls. Kidney B12 levels in deficient babies were about one quarter those of the replete babies. Brain vitamin B12 levels in B12-deficient sucklings were significantly lower than those of B12-deficient adult bats (P less than 0.01). These findings reinforce the need for adequate vitamin B12 nutrition in pregnant and lactating animals.
维生素B12缺乏的幼蝠（埃及果蝠，4 - 20日龄）大脑的重量略低于维生素B12充足的幼蝠。两组的肝脏和肾脏器官重量相似。维生素B12缺乏的幼蝠大脑和肝脏中的B12水平显著低于充足对照组。缺乏组幼蝠肾脏中的B12水平约为充足组幼蝠的四分之一。维生素B12缺乏的哺乳幼蝠大脑中的维生素B12水平显著低于维生素B12缺乏的成年蝙蝠（P小于0.01）。这些发现强化了怀孕和哺乳期动物获得充足维生素B12营养的必要性。
