Effect of Diets High in Fat or Protein on Vitamin B 12 Deficiency in Non-depleted Chick

Abstract

Summary

A severe vit. B₁₂ deficiency, as indicated by poor growth, was produced by dietary means in non-depleted chicks. Replacing 20% of the corn in an all-vegetable corn-soybean oil meal diet with 20% fat increased the weight difference between chicks receiving vit. B₁₂ and the unsupplemented birds. A less striking effect was obtained with 20% vegetable protein.
