Rumen Acidosis in Cattle: Welfare and Dietary Management

Preventing and managing rumen acidosis to protect cattle welfare in intensive systems.

Key Facts

Acidosis occurs when rumen pH drops due to excess rapidly fermentable carbohydrate
Acute acidosis can cause death — subacute acidosis causes chronic welfare compromise
Laminitis, liver abscesses, and reduced immunity are linked to subacute acidosis
Dietary transition management and adequate effective fibre prevent most cases

Welfare Considerations

Rumen acidosis causes significant welfare harm ranging from chronic discomfort and laminitis to acute metabolic crisis and death. Welfare-focused nutrition manages transition from forage to concentrate diets carefully, ensures adequate physically effective fibre, and avoids competitive feeding that causes rapid high-starch ingestion by subordinate animals.

What You Can Do

Implement stepwise concentrate introduction over 3-4 weeks at housing
Ensure adequate roughage in diet and regular feed space to reduce competition
Monitor dung consistency as an early indicator of subacute rumen acidosis
