Analysis of the Stability of Rumen pH Measurements Obtained Postmortem in Feeder Calves

Abstract

The value of rumen pH readings postmortem as a diagnostic aid in feeder cattle has long been debated. Obtaining a rumen pH measurement as part of a routine postmortem examination has been described to help determine cause of death due to digestive system disorders such as acidosis. Some dispute the use of pH readings, arguing that rumen pH will continue to change after death, yielding inaccurate results. The goals of this study were to determine the difference in postmortem pH levels between cattle fed one of two diets, and to determine how stable postmortem pH is over a 24-hour period.
