Extract

The literature specifically related to the effect of vitamin B12 on methyl group synthesis and its relationship to protein utilization in experimental animals is discussed.

The techniques and results of nitrogen balance experiments on control A.P.F.-deficient chicks and vitamin B12-treated chicks are presented.

Results show that vitamin B12 administration does not result in any direct effect on nitrogen retention or efficiency of utilization when control and B12-supplemented chicks are pair-fed. This finding is discussed in relation to the response of A.P.F.-deficient chicks to vitamin B12 and the significance of appetite as a factor in the response is suggested.
