Effect of Vitamin B12 on the Growing Pig

Abstract

Under the conditions of the experiment reported herein, no advantage was shown by adding a vitamin B₁₂ concentrate, crystalline vitamin B₁₂ (injected), an “animal protein factor” concentrate, or alfalfa and fish meal to a purified basal ration for the growing pig. No significant differences were found in average daily gain, pounds of feed per pound of gain, hemoglobin levels or red and white blood cell counts between the various lots of pigs in this experiment. Further research needs to be done on the requirement for this vitamin by the growing pig. Copyright © . .
