Studies upon the Relation of Nutrition to the Development of Necrotic Enteritis in Swine. II. Nicotinic Acid, Yeast and Liver in the Prevention of Necrotic Enteritis in Young Pigs Fed Massive Doses of S. Choleraesuis

Michigan Agricultural Experiment Station

Abstract

In a previous publication from the Michigan Station (1) a report was made of experiments in which it was noted that swine on certain rations, particularly those on a ration made up chiefly of corn, appeared to be especially susceptible to the development of a necrotic enteritis even when maintained under conditions of strict sanitation. It was also noted that swine receiving other rations, but kept in the same pens with those fed the corn ration, appeared to be much more resistant to the development of this disease.

An effort to ascertain the cause for the apparent difference in resistance to the development of the enteritis led to the observation that pigs fed liver, yeast and nicotinic acid developed the necrotic enteritis in far less instances than pigs similarly fed but without the supplements. In the experiments mentioned cultures of Salmonella choleraesuis were not fed and the pigs could obtain the organism only from the pens.
