Abstract
Three methods of preservation and storage of hay, field-cured, mow-cured, or ensiled were compared as to their effect upon vit. synthesis in the digestive tract of the dairy cows, with no significant difference upon excretion of nicotinic acid, pantothenic acid or riboflavin. Silage apparently favorably affected the synthesis of thiamine. As a feed for dairy cattle wood molasses was found to be comparable to. cane molasses with respect to its effect upon rumen or intestinal synthesis of nicotinic acid, thiamine and pantothenic acid. In the case of pantothenic acid, this synthetic activity was considerably increased when molasses was present.
