Farm Animal Welfare

Cattle Subacute Ruminal Acidosis Monitoring

SARA is a widespread subclinical welfare condition in high-producing dairy cows that often goes unrecognized. Monitoring enables earlier intervention.

Key Facts

SARA is defined as rumen pH below 5.8 for more than 3 hours per day
Wireless rumen boluses can monitor pH continuously
Behavioral signs (reduced feeding time, sorting) precede clinical disease
SARA causes laminitis, liver abscess, and reduced immune function
Dietary fiber management is the primary prevention strategy

Welfare Considerations

Cows with SARA experience persistent rumen acidosis causing subclinical pain and predisposing to serious secondary conditions. The subclinical nature means animals suffer without obvious signs detectable through conventional observation. Monitoring technologies that reveal SARA at herd level enable dietary adjustments that prevent cumulative suffering.
