Rumen Acidosis in Dairy Cattle — Causes and Prevention
Updated 08 Jul 2026 • By Falah Nutrition Desk, Animal Nutrition Advisor
Rumen acidosis happens when rapidly-fermenting feed drops rumen pH too low for the rumen's normal microbes to function well. Sub-acute (mild, ongoing) acidosis is especially common and easy to miss, quietly reducing milk yield, fat percentage and hoof health over time.
Common Signs
- Reduced or inconsistent feed intake
- Loose, frothy or inconsistent dung
- Drop in milk fat percentage
- Reduced rumination (cud chewing) time
- Associated lameness or laminitis over time in chronic cases
Possible Causes
- Too much rapidly-fermentable concentrate relative to fibre in the ration
- Large single concentrate meals instead of split feeding
- Sudden feed changes without a gradual transition
- Insufficient effective fibre (long-stem dry fodder) in the overall diet
- Over-processed or very finely ground concentrate feed
What the Farmer Should Check
- Is concentrate feed split into 2-3 meals a day, or fed as one large portion?
- Is there enough dry fodder or straw in the ration relative to concentrate?
- Was a recent feed change made gradually, or all at once?
- Is the animal ruminating (chewing cud) normally between meals?
Feed Guidance
Prevention centers on feeding pattern as much as feed choice: split concentrate into at least 2, ideally 3, feeds through the day rather than one large portion, which keeps rumen pH more stable. Maintain adequate dry fodder or straw in the ration — fibre supports normal chewing and saliva production, which naturally buffers rumen pH. Make any feed or brand change gradually over 7-10 days rather than switching abruptly. GOKA feeds are formulated for balanced fermentation when fed correctly at the right split quantities — most acidosis problems trace back to feeding pattern rather than the feed itself. Persistent signs despite correct feeding pattern warrant veterinary consultation.

When to Contact a Veterinary Doctor
For serious symptoms, consult a qualified veterinary doctor. Feed support can help overall nutrition and recovery but should not replace veterinary treatment.
