Physiological alterations and predictors of death in neonatal calves with weak calf syndrome.

ABSTRACT:

Background

Weak calf syndrome (WCS) is characterised by weakness, poor vitality and difficulty standing or suckling. Early identification of physiological alterations and prognostic indicators is critical for improving the management and survival of weak calves.

Methods

Twenty-six neonatal calves, aged 1-5 days, that were unable to stand or suckle were analysed for electrolytes, blood gases, serum biochemistry and protein electrophoresis. The prognostic utility of these variables was then evaluated using receiver operating characteristic analysis.

Results

Twenty calves survived, while six died-four on the first day, one on the fourth day and one on the seventh day. Surviving calves lived for at least 90 days. Hypothermia occurred in 16 calves, elevated pCO₂
