A Comparison of Two Methods for Obtaining Anaerobic Counts in Different Segments of the Gastro‐intestinal Tract of Piglets

摘要

Summary.The total anaerobic count on contents of the gastro‐intestinal tract of 7 piglets, fed on a milk powder diet, was determined with the ringed plates technique of Van der Heyde and the roll tube method of Hungate. Simultaneously, the oxidation‐reduction potential (Eh) was measured in the different segments. For caecal and large intestinal contents, higher counts were obtained with the roll tube method. Nevertheless, the proportional composition of the dominant flora was identical for both methods. Marked differences between theEhof the different gastro‐intestinal segments were obs
