Cattle Liver Abscess Welfare in Feedlots

Liver abscesses are a significant welfare problem in feedlot cattle linked to high-concentrate diets causing subacute rumen acidosis.

Key Facts

Liver abscesses form when bacteria breach a damaged rumen wall following subacute acidosis
Prevalence in feedlot cattle can reach 30-40% without diet management
Affected cattle show reduced feed intake and production but rarely obvious clinical signs
Rumination time monitoring detects subacute acidosis before liver damage develops
Dietary transition management reduces acidosis risk and liver abscess prevalence

Welfare Considerations

Liver abscesses represent chronic subclinical welfare harm affecting large proportions of feedlot cattle. The subclinical nature means welfare compromise goes unrecognised. Dietary management preventing subacute acidosis prevents this welfare harm as well as production loss.

What You Can Do

Advocate for feedlot dietary management standards that prevent subacute rumen acidosis
Support research into welfare monitoring in feedlot systems including liver abscess prevalence measurement
Ask beef producers about their feedlot dietary management and rumen health protocols
