Diarrhea in cattle of all types continues to hinder both production and welfare. This study examined 157 cases of bovine diarrhea submitted to the Animal Diagnostic Lab (State College, PA) between January 2014 and September 2015. It was hypothesized that causes of diarrhea in these cattle would differ between age groups. While trends indicated this, the findings were not statistically significant. It is speculated that this was much due to the retrospective nature of the study. However, this examination provided valuable framework for further examination. With improvements and a change to a prospective organization, these findings have the potential to become solidified information that would assists farmers in better understanding diarrhea’s causes leading to more efficient control of the spread of these pathogenic agents.
