Paralytic ileus of infectious origin

Piedmontese calf, approximately 2 months old. The medical history reports a severe febrile condition in the days preceding the call, treated with antibiotics and NSAIDs.
The animal appears listless, inappetent, with a rough coat; the umbilicus is normal, and the temperature is 38°C (100.4°F). Respiratory and heart rates are within normal limits; auscultation excludes respiratory pathologies, while there is an absence of peristaltic movements in the abdomen. Urolithiasis has been ruled out.
