Blood gases, acid-base, and metabolic alterations in calves with bronchopneumonia diagnosed via clinical signs and thoracic ultrasonography: A cross-sectional study.

ABSTRACT:

Background

Bronchopneumonia (BP) in calves potentially causes systemic changes.

Objectives

To describe metabolic, arterial blood gas, and acid-base disorders in calves with BP diagnosed by thoracic ultrasound (TUS), Wisconsin score (WISC), and combinations of WISC and TUS.

Animals

Two hundred thirty-one dairy preweaned dairy calves from 13 dairy farms.

Methods

Cross-sectional study. Each calf sequentially underwent arterial blood gas evaluation, WISC score, venous sampling, and TUS. Calves were grouped based on a single diagnostic method and combination of WISC and 2 TUS cutoffs (≥1 cm; ≥3 cm) as healthy, upper respiratory tract infection, subclinical BP, and clinical BP.

Results

Oxygenation and acid-base variables were unaffected. Glucose concentration
