Abstract
Summary
Vit. B-12 has been shown to reduce blood levels of non-protein nitrogen and of 7 individual amino acids from the levels found in vit. B-12 deficient chicks.
Chicks given vit. B-12 grew more rapidly and utilized feed more efficiently than B-12 deficient controls, although the latter had higher blood levels of amino acids.
Vit. B-12 appears to function in metabolism by enhancing utilization of circulating amino acids for building fixed tissues.
