Effect of Sulfur Dioxide-Silage on Vitamin Excretion by Ruminants

Abstract
Insofar as nicotinic acid, riboflavin and thiamine are concerned, in ruminant nutrition, sulfur dioxide appears to be a highly satisfactory silage preservative. Although sulfur dioxide destroys much of the thiamine in the silage, it counteracts the deficiency by producing conditions in the rumen favorable to the synthesis of this vitamin. The alkalinity resulting from the feeding of limestone is unfavorable to the intestinal or rumen synthesis of thiamine. Copyright © . .
