Abstract

The growth promoting activity of vitamin B₁₂ in rats has been demonstrated by many workers. Earliest among them was Emerson (1949) who showed that the retarding effect of thyroid powder when given to rats was counteracted by oral administration or subcutaneous injection of vitamin B₁₂. Since 1949 many others have demonstrated the beneficial effect of B₁₂ in augmenting growth in the young of several mammalian and avian species. Bioassay procedures for the estimation of vitamin B_B are based on the capacity of B₁₂ to stimulate growth. Cheng and Thomas (1950) showed that not only was growth enhanced but also food efficiency was improved by injecting "protamonized" rats with vitamin B₁₂.
