Abomasitis is a pathological condition reported in calves. The current description is mainly limited to post-mortem findings. The objectives of this retrospective study are to describe clinical presentation and outcomes in calves with a primary ante-mortem diagnosis of abomasitis.

Medical archives from the Centre Hospitalier Universitaire Vétérinaire of the Université de Montréal from 2006 to 2016 were searched using terms referring to abomasum. After exclusion of calves with clinical co-morbidity factors and/or older than three months old, twenty calves with clinical diagnosis of abomasitis were included. The median age was 2.5 days old (range: 0-30 days). Most calves were Holstein (19/20). The median clinical duration prior to admission was 24 hours (range: 0-4 days). Abomasal tympany (20/20), positive succussion (11/12), abnormal mucous membrane color (13/15), dehydration (12/14), depression (14/17), recumbency (13/16), tachycardia (14/19; range 80-240 beats/min) and tachypnea (12/19; range 32-128 breaths/min) were the most frequent clinical signs noted. Hematological and biochemical profiles revealed hyperlactatemia (13/13; range: 3.3-16.3 mmol/L), hypochloremia (12/16; range 77.8-106 mmol/L), left shift (13/19), neutrophils’ toxic changes (10/15), hypoglycemia (11/17; range: 0.3-10.9 mmol/L), hyperkaliemia (9/18; range: 3.6-8.3 mmol/L), acidemia (6/13; range: 6.8-7.5) and neutropenia (5/15; range: 1.6-22.7 cellsx109/L). Based on univariate statistical analysis, fatal outcome was significantly (p < 0.05) related to dehydration, recumbency, hypothermia, metabolic acidosis, hypoproteinemia, leucopenia and neutropenia. Fatality rate was 60% (12/20). Necropsy was performed on 11 calves and confirmed the clinical diagnosis.

Abomasitis has a guarded prognosis in calves. Clinical and clinicopathologic findings were shown to be associated with a fatal outcome.
