The concentration of vitamin B12 and its binding proteins was measured in the impala, nyala, wildebeest, zebra, bushpig, warthog, and rhino, all existing in their natural state. Marked differences were found between some species. The variations observed are probably true species differences, unrelated to environmental factors.
对自然状态下的黑斑羚、林羚、角马、斑马、非洲野猪、疣猪和犀牛体内的维生素B12及其结合蛋白浓度进行了测量。发现某些物种之间存在显著差异。观察到的这些变化可能是真正的物种差异,与环境因素无关。
