Peritoneal Fluid Analysis on Intraoperative Samples in 32 Clinically Healthy Female Companion Pigs and Transabdominal Samples From 10 Clinically Ill Companion Pigs

Key Points

To investigate peritoneal fluid characteristics in healthy versus clinically ill companion pigs.
Analyzed peritoneal fluid samples from 32 healthy female companion pigs.
Collected transabdominal samples from 10 clinically ill companion pigs with conditions like peritonitis.
Measured total nucleated cell count (TNCC) and proportion of neutrophils in the samples.
Clinically ill pigs showed similar TNCC compared to healthy sows, but with significantly higher neutrophil proportions.
High neutrophil percentages in peritoneal fluid indicate potential peritonitis or abdominal neoplasia, regardless of TNCC.

Abstract

PTF fluid from companion pigs with peritonitis or uterine neoplasia, particularly with concurrent inflammation, may have similar TNCC but increased proportions of neutrophils compared to healthy sows. Therefore, in contrast to some other large animal species, high percentages of neutrophils in PTF may warrant evaluation for peritonitis or abdominal neoplasia in pigs, regardless of the TNCC.
