Apparatus for Obtaining Ruminoreticular Samples and the Effect of Sampling Location on pH and Volatile Fatty Acids

Abstract

An apparatus for obtaining nonaerated fluid samples from the ruminoreticulum via a ruminal fistula and simultaneous measurement of pH is described. The apparatus was used to determine the effect of sampling location in the ruminoreticulum on pH and the concentration and ratio of volatile fatty acids (VFA). The data obtained indicate that ruminal pH and VFA concentration varied with location, but the ratio of VFA was not affected. © 1968, American Dairy Science Association. All rights reserved.
